Suspension update coming for Porsche 963

The Porsche 963’s front suspension looks set to be updated ahead of the 2025 FIA WEC and IMSA seasons, according to Urs Kuratle, Porsche’s factory LMDh racing boss. If given the green light by the rule-makers, this will be the car’s second “Joker” …

The Porsche 963’s front suspension looks set to be updated ahead of the 2025 FIA WEC and IMSA seasons, according to Urs Kuratle, Porsche’s factory LMDh racing boss. If given the green light by the rule-makers, this will be the car’s second “Joker” evolution after the German marque debuted sensor updates ahead of the 2024 Rolex At Daytona back in January.

“We have wishes, we handed in our wishes to the governing bodies — IMSA and the ACO — and once we get approved we will introduce the changes to the front-suspension parts for the [IMSA] test at Daytona at the end of the month,” Kuratle told RACER.

The updates to the suspension, Kuratle believes, should have an impact at a variety of circuits next year, by providing 963 teams more flexibility with setup.

“This is an area that the engineers and drivers gave feedback on [and] we thought it was a route to explore,” he said. “It will give us more adjustments to the suspension. Throughout the year it will help us, it will make the 963 a more equal car at every track.

“Testing [at France’s Paul Ricard circuit and on the dyno] with it has been positive, and once we were sure we handed in the paperwork. We are just waiting for it to be approved so we can start producing parts and distributing them. We need to be ready for the race at Daytona (next January), getting the cars equipped and with relevant spares.

“We have to be careful because you only have so many ‘Jokers’ you can make. It has to make sense, and it has to make sense in the rules. But we are confident it’ll make the car better.”

This news comes after Porsche previously shelved its plans to update the 963 with a new 90-degree crankshaft earlier in the year to counteract vibration issues with the car.

“It’s [about saving] tokens but to be really honest, it’s even more the money,” Kuratle told RACER back in June Le Mans week when asked why its plans to shift to the new crank were being scrapped. “If we would have to change the crankshaft for a good reason it will cost us a lot of money because we will have to update the customer cars as well. But the reliability of the 963 has improved a lot and it (vibrations) doesn’t seem to be an issue anymore.”

Vettel to test a Porsche 963

Four-time Formula 1 world champion Sebastian Vettel is entering new territory as he prepares to test a Porsche 963 in a 36-hour test conducted by Porsche Penske Motorsports at Motorland Aragon in Spain. “I’m looking forward to testing the Porsche …

Four-time Formula 1 world champion Sebastian Vettel is entering new territory as he prepares to test a Porsche 963 in a 36-hour test conducted by Porsche Penske Motorsports at Motorland Aragon in Spain.

“I’m looking forward to testing the Porsche 963” said Vettel. “I’ve always followed other racing series and my curiosity for endurance events encouraged me to just give it a shot. Now I’m excited about the long run in Aragon and I’m looking forward to my time behind the wheel. It’ll definitely take an adjustment and some getting used to, but everyone in the team is very open and helps me.

“This will be a new experience for me. We will then see what happens next in this respect — at the moment there are no further plans for the future.”

The German driver has already prepared extensively for the test, having met the operations crew at the Porsche Penske Motorsport facility in Mannheim and completing an extended simulator session at Porsche Motorsport. He had a brief taste of the 963 on the in-house test track at the Weissach R&D Center. It proved to be an unusual experience for the 36-year old; after 299 F1 starts, it had been some time since Vettel had driven a racing car with a roof – previously only at the Race of Champions or turning demo laps.

Joining Vettel for the test next week at Aragon are Porsche factory drivers Matt Campbell, Michael Christensen, Frédéric Makowiecki, Kévin Estre, André Lotterer and Laurens Vanthoor. The endurance test serves as preparation for the 24 Hours of Le Mans, where Porsche is aiming for a 20th overall victory.

“We’re delighted that Sebastian Vettel is interested in our Porsche 963,” said Thomas Laudenbach, Vice President Porsche Motorsport. “There was no question for us that we’d be thrilled to support his request for an opportunity to test and provide him with extensive preparation and plenty of time to drive our hybrid prototype — there’s no doubt we’ll learn a lot from his valuable feedback. Our 36-hour long run with Porsche Penske Motorsport and our works drivers at Motorland Aragón offers a perfect environment for this.”

The 963 and Porsche Penske Motorsport have had an excellent start to the 2024 season, winning both the opening round of the World Endurance Championship in Qatar as well as the season opener for the IMSA WeatherTech SportsCar Championship, the Rolex 24 At Daytona. PPM will enter three 963s at Le Mans, in addition to entries from privateer teams Hertz Team JOTA and Proton Competition.

Button joins JDC-Miller Porsche GTP team for Petit Le Mans

Jenson Button is joining JDC-Miller Motorsports’ Porsche GTP lineup for October’s Motul Petit Le Mans at Michelin Raceway Road Atlanta, the team has announced. In making his IMSA WeatherTech SportsCar Championship debut, Button – the 2009 Formula 1 …

Jenson Button is joining JDC-Miller Motorsports’ Porsche GTP lineup for October’s Motul Petit Le Mans at Michelin Raceway Road Atlanta, the team has announced. In making his IMSA WeatherTech SportsCar Championship debut, Button — the 2009 Formula 1 world champion — will reunite with NASCAR Garage 56 co-driver Mike Rockenfeller and Tijmen van der Helm in the No. 5 Porsche 963.

British driver Button, who now lives in Los Angeles, teamed earlier this year with Rockenfeller and seven-time NASCAR Cup Series champion Jimmie Johnson to race the NASCAR Garage 56 Chevrolet Camaro at the 24 Hours of Le Mans. More recently, Button has become a part-time competitor in the NASCAR Cup Series, with a best finish of 18th place in three road course races for Rick Ware Racing.

“While I’m having a lot of fun cutting my teeth in the NASCAR Cup Series this year, a prototype with high downforce is definitely more in my comfort zone,” Button said. “That said, the Porsche 963, the IMSA WeatherTech SportsCar Championship and Road Atlanta are all brand-new to me, so I can’t wait to tackle all three with my teammates for the weekend.

“I partnered with Rocky at Le Mans this year and he will be invaluable as he’s fantastic at car/team development. He is also incredibly quick, which always helps! I’ll also have the pleasure of working with rookie Tijmen van der Helm, who seems to really be gaining speed and confidence through the season so we should have a lot of fun.”

[lawrence-auto-related count=3 category=1406]

The No. 5 Porsche 963 has shown steady progress since its mid-season debut at WeatherTech Raceway Laguna Seca, where JDC-Miller became IMSA’s first customer team to field a 963. In the last three races, Rockenfeller and van der Helm have delivered two fourth-place finishes and a fifth-place result.

“Having Jenson join JDC-Miller MotorSports is a testimony to the program John Church, John Miller and the entire team has assembled,” said Volker Holzmeyer, president and CEO of Porsche Motorsport North America. “It also speaks to the high level of competition and interest in the IMSA GTP class. Rocky and Tijmen have proven how successful a privateer can be with the Porsche 963. The addition of Jenson should bring even greater success.”

The 26th annual Motul Petit Le Mans is set for Oct. 11-14 at Michelin Raceway Road Atlanta.

Proton WeatherTech 963 to make IMSA debut at Road America

Proton Competition has revealed the livery and driver lineup for its Porsche 963 that will debut at Monza before attentions turn to the U.S. for a trio of IMSA WeatherTech SportsCar Championship races beginning at Road America in August.

Carrying the colors of series sponsor WeatherTech — Proton Competition currently runs the Mercedes AMG for GTD PRO team WeatherTech Racing — the Porsche will be driven by Gianmaria Bruni and Harry Tincknell, with Neel Jani on board for Monza. It also carries a throwback FAT International logo that was a familiar sight on Porsche race cars of the past, although now an automotive lifestyle and promotions company rather than the logistics company it was then.

For both Tincknell and Bruni, Road America will mark a return to the IMSA paddock. Tincknell most recently competed with AO Racing in its GTD-class Porsche 911 GT3R at Daytona, but his last full-season appearance came with Mazda in its DPi program in 2020-21. Prior to that he was with Chip Ganassi Racing and Ford in its GT GTLM efforts, and has recently been working with Ford to develop the new Mustang GT3. The last couple of years he has raced with Proton and Dempsey-Proton in WEC and at Le Mans.

[lawrence-auto-related count=3 category=1406]

Bruni has been tied with Porsche since 2017, although he was a Ferrari driver prior to that. He was part of the winning LMP2 squad for Proton Competition at this year’s Rolex 24 At Daytona, and was competing with WeatherTech Racing at Daytona last year.

The Proton car marks the second customer Porsche 963 in the WeatherTech Championship, JDC-Miller Motorsports having brought theirs to the party beginning at Laguna Seca in May.

First GTP customer team JDC-Miller on steep learning curve at Laguna

JDC-Miller Motorsports are thrilled to have their shiny, new and very yellow Porsche 963 make its debut in this weekend’s IMSA WeatherTech SportsCar Championship Motul Course de Monterey. Becoming the first customer team in a field of factory …

JDC-Miller Motorsports are thrilled to have their shiny, new and very yellow Porsche 963 make its debut in this weekend’s IMSA WeatherTech SportsCar Championship Motul Course de Monterey. Becoming the first customer team in a field of factory efforts is an honor. But at the same time, they arrived at WeatherTech Raceway Laguna Seca with no testing, and no experience with the car other than the crew putting it together with the Porsche engineers in Weissach. Just finishing the race will be an achievement.

“For me, (being the first customer team is) a big accomplishment,” said team principal John Church. “It’s nice to get back to the top class here. Sure, this weekend, we’ll be running around at the back, but use it as a test session, learn how everything works, learn how the tires work, learn how we work with the drivers, the communication…everything is an unknown at this point. I keep saying you’ve got to start somewhere, and we’re starting here at Laguna.”

The team found its first issues early, making only a handful of laps in the first practice session on Friday. Tijmen van der Helm only had his first laps in the car on Saturday morning, but pace kept improving, and in qualifying van der Helm put in a time that — although two seconds off the GTP pace — was in the ballpark of where the other teams had started Friday afternoon in Practice 1. Not bad for being “thrown under the bus,” as the other half of the driving team, Mike Rockenfeller, put it.

“With the experience I have, I have seen a lot of things in my life and racing, for sure. But still, at the end, every project is unique. And it’s definitely not an easy one without any testing. You know, I think if we had two, three days, you feel kind of prepared. Now it’s a bit…we’re a bit thrown under the bus, all of us, but I think we are in the same boat. I try to stay calm and just do it step by step, don’t expect too much. But then we all know once the race comes, the flag drops, you want to do as good as you can. But I see it as a test here for everybody, and then get our hands around this thing,” said Rockenfeller.

Urs Kuratle, Porsche’s director of Factory Racing, LMDh, says Porsche Motorsports will do everything possible to help JDC-Miller get up to speed, even as they try to catch up to their own internal struggles to produce cars and spares amid ongoing supply chain issues.

[lawrence-auto-related count=3 category=1406]

“We do whatever we can, and we do whatever is necessary,” declared Kuratle. “Obviously, this is still a prototype, it’s still, even for the works team, a new thing. And we are learning a lot every lap we are out there. We transfer all the information straightaway to all of our customers as we do with Jota Sport in WEC, and we will with JDC-Miller motorsports here in the IMSA Series. And we have to communicate very good because we already have two works teams. Now we have two customers, and to bring all the information together, it’s a big effort. But so far, so good. We are really happy (with) how it works so far, and we try to support as much as we can.”

The name of Porsche’s prototype is designed to evoke the 962, the race car of choice for many customer teams in the original era of GTP. IMSA President John Doonan is happy to see a customer car in the series, and says both the car and the team are appropriate.

“You look back at the history of GTP, in its heyday, if you will, the customer teams were really the lifeblood of the series, the category itself, and the growth of the championship,” Doonan said. “For me, this is a perfect model of that. And I think the fact that it’s JDC…I’ve had relationships with John Church and John Miller for some time. They’re a race-winning and, in several divisions, championship-winning team, so they’re not rookies at this. Obviously, these cars are highly technologically advanced compared to other cars in the world, and to have them be the first one, I think it’s pretty fitting for me, personally. But the other part of it is, IMSA’s foundational values are about customer racing and that’s a very stable and sustainable way that we will grow as a series. So to have these guys be the first one is, for me, special, but I think for us as a championship, it’s also quite special.”

JDC-Miller Motorsports has a long road ahead of it to get close the Porsche Penske Motorsports factory effort. This weekend is merely a small first step, but it’s a crucial one. And, so far, so good.

“We want to make every session and run as many laps as we can,” said Church. “It’s a test weekend, just getting a feel for everything. And like I keep telling the guys — we’re here to learn all the stuff we don’t know. There’s a lot of things we don’t know… So we got gotta go and run and figure it out.”

Porsche’s global GTP program brings parts supply challenges

Supporting customer GTP teams has presented Porsche with markedly different challenges than it’s been accustomed to with traditional GT3 customer outfits. Ongoing work to produce enough cars and spares as its three-car Le Mans effort looms only …

Supporting customer GTP teams has presented Porsche with markedly different challenges than it’s been accustomed to with traditional GT3 customer outfits. Ongoing work to produce enough cars and spares as its three-car Le Mans effort looms only serves to add more complexity.

“It’s certainly a big difference because the car is much more complicated,” Urs Kuratle, Porsche Motorsports’ Director of Factory Racing explained. “As you can see, there is a lot of equipment and especially a lot of software to take care of. The customer support program is much more difficult than in a GT car. Certain things are the same, but to set up the support program and to bring the team up to speed — that’s a big focus.”

JDC-Miller Motorsports — Porsche’s newest partner — is entering this weekend’s IMSA WeatherTech SportsCar Championship round with hardly anything in reserve.

“What I hear is zero (spares),” driver Mike Rockenfeller explained. “Maybe we have a few, but honestly I feel there is not much, and I think Jota was in the same situation at Spa. You have to start going at a certain point, otherwise we wouldn’t be here, and in six months still saying, ‘Oh, there are no parts; we cannot race; we need more time.’ I think we just go and see what happens.”

Incidents in the opening round of the IMSA championship have placed the whole global operation on the back foot.

“As we are racing in both (IMSA and the WEC) in parallel, we have to have spare parts on both sides of the ocean and that’s a big effort. We need a lot, a lot, of spare parts,” Kuratle said. “In the first few races we had quite a lot of contact on track as well, so we lost quite a lot of bodywork and parts there. It’s a big effort for us to have it all up to speed.”

Kuratle told to RACER that the three Porsche 963 chassis that Porsche Penske Motorsports will use at Le Mans will be the two World Endurance Championship chassis combined with one from the IMSA side.

JDC-Miller Porsche GTP set for Laguna with Rockenfeller and van der Helm

Having taken delivery of its Porsche 963 LMDh, JDC-Miller MotorSports is planning its IMSA WeatherTech Championship GTP debut at WeatherTech Raceway Laguna Seca in two weeks with Mike Rockenfeller and Tijmen van der Helm as the drivers. The team’s entry marks the first customer effort in the new GTP category.

“We are very proud to announce the new driver lineup for our 2023 GTP campaign with the Porsche 963,” said team managing partner John Church. “It represents a balance of youth and experience and features a tremendous amount of on-track success. This pairing combined with the Porsche 963 will allow us to compete for wins in IMSA.”

Rockenfeller has a long history in sports car competition, including stints as a factory driver for Porsche, Audi and Corvette. That includes a pair of victories at the 24 Hours of Le Mans, as well as Daytona and Sebring, plus a DTM title. The German will be at Le Mans this year as part of the NASCAR Garage 56 program with Jjmmie Johnson and Jenson Button.

“I am excited to be part of this team and the Porsche 963 project,” said Rockenfeller. “Starting our GTP season at WeatherTech Raceway Laguna Seca for the fourth round of the season is going to be a challenge. I am confident the JDC-Miller MotorSports team is on a very steep learning curve and will compete with the GTP teams very quickly. So very happy to see my name back on a Porsche.”

[lawrence-auto-related count=3 category=1406]

JDC-Miller entered the LMP3 class at Daytona and Sebring in preparation for competing with the 963, with a driver lineup that included van der Helm. In 2022, he competed in the FIA World Endurance Championship and the European Le Mans Series in the LMP2 class, including his first start at Le Mans.

“I am really happy to be a part of JDC-Miller MotorSports Porsche 963 LMDh project,” the 19-year-old Dutch driver said. “To me it does not really matter that we start a bit later in the season. I think we as a team can maximize every opportunity we will get. Going to the Laguna race with a brand-new car will be tough, but I have no doubt that we will be competitive as a team. I look forward to the challenge and opportunity!”

JDC-Miller was announced as the first IMSA customer team for Porsche last July. But supply chain constraints left Porsche without the resources to deliver cars beyond the Porsche Penske Motorsports factory efforts before the start of the season. Both JDC-Miller and WEC team JOTA Sport received their 963s a few days ago.

The stalwart IMSA team, which competed with Cadillac in the final season of DPi competition last year, also runs programs in the VP Racing SportsCar Challenge and the Michelin Pilot Challenge TCR category.

Porsche Hypercar team bolstered by Portimao podium, but realistic about pace

Like its Hypercar revivals at Ferrari, with whom it will share the Monza circuit for a pre-Le Mans test, Porsche Penske Motorsport is feeling more bullish about the prospects for the Porsche 963 following a more successful FIA WEC race in Portimao. …

Like its Hypercar revivals at Ferrari, with whom it will share the Monza circuit for a pre-Le Mans test, Porsche Penske Motorsport is feeling more bullish about the prospects for the Porsche 963 following a more successful FIA WEC race in Portimao. The team netted its first podium finish, with its No. 6 963, driven by Kevin Estre, Laurens Vanthoor and Andre Lotterer, on a weekend which saw the IMSA arm of the program score the 963’s first win globally at Long Beach.

Speaking to RACER after the 6 Hours of Portimao, Estre was generally positive about the team’s progress in extracting more pace out of the 963.

“We were all very down after Sebring — it was a very tough weekend for the whole Porsche Penske motorsport group,” he said. “We worked really hard between then and now to try and improve the car’s reliability and performance.”

However, Estre stressed that there is still a long way to go and a lot of speed to find if it is to challenge Toyota and Ferrari for race wins. At Sebring the Penske team’s cars finished a distant fifth and sixth in the WEC 1000 Miles, four laps off the winning Toyota. In Portugal, Porsche’s lead car was much closer, but the No. 6 crew, still crossed the line off the lead lap.

“(Despite the improvement in form) we proved in the USA that the performance is not where we want to be, in qualifying in both the USA and WEC, on one-lap pace,” Estre admitted.

“I think we did a good job on both sides of the Atlantic on strategy, on tire calls. Pretty much everyone made mistakes in Long Beach and here, and we were closer to everyone else, which I think pushed people into mistakes.

“I think we can improve on our side. We made a small step, but it’s not enough — we are too far from Toyota. There are still some steps to come. If it’s enough or not is another question.

“At the moment we are really far (back) in performance. Even if we execute the race well we are one or two laps down, which is too much. I am not sure if this is all in our hands, we don’t have the data. We have to be confident in the FIA and ACO.

“You have to keep in mind that one Toyota had an issue (at Portimao), and a Ferrari had an issue. Other than that it would have been very hard to beat them. On performance, our position is more fourth and fifth rather than third. I think it’s still Toyota in front of Ferrari, and then us, which was nice because it was Cadillac after them in Sebring.”

[lawrence-auto-related count=3 category=1416]

It must be noted though that the No. 6 Porsche didn’t enjoy an entirely perfect race. The drivers battled power steering issues throughout, which Estre said made the car tough to drive. “It didn’t impact performance, I think, but as drivers, we were happy to only do double stints and not a triple,” he said.

Thankfully the handling issues for Estre and company weren’t as catastrophic an issue as the sister car’s power steering woes, which forced it into the garage for repairs that cost the team a huge chunk of time. The No. 6 also lost time at the end of the race to an additional stop, the car forced to come in for a splash in the closing laps. Estre admitted that “there wasn’t enough fuel in the car” to make it home.

“We were luckily we spotted it early,” he added.

What may help Porsche, and fellow LMDh manufacturer Cadillac at Spa, is a change to the Platform BoP, which can be made every two races (the BoP for individual cars is frozen until after Le Mans to prevent the temptation for teams to hold back performance ahead of the 24 Hours). Whether or not the ACO and FIA decide to give the LMDh cars a significant boost for the race in Belgium remains to be seen.
