Turbo GT Weissach doing what it was built for

[Batattack]

I race in the Time Attack EV class and am probably one of the few people doing so with this car. I’m planning to install a 6-point harness and am currently looking into how to mount the two anti-submarine belts that attach beneath the seat.

For the 911 platform there seem to be ready-made mounting solutions available, but I haven’t been able to find anything similar for the Taycan. I thought I’d ask here on the forum if anyone knows how to properly install a 6-point harness in a Taycan Turbo GT, or knows a company or person with experience doing it.

I’m also building my own version of the Manthey kit for the car, and the plan is to compete at the Nürburgring this October in the European Time Attack Masters event. The official Manthey package for the Turbo GT has been a great source of inspiration for the project.

If anyone is interested in following the car, the races, and the development throughout the season, you can find me on Instagram at @batattackgt

This is great!

How have your results been for the car on the track? Any feedback?

Unfortunately in the US, we only get the 18way seats, not the bucket seats


Here are some more Manthey details

The car is excellent on track for such a heavy vehicle. Its biggest challenge has been understeer and front-end grip. Those have improved with the addition of a front splitter and more effective air extraction from the front wheel wells, but there is still room for improvement.

The car is significantly faster than the Taycan Turbo S (2020–2024), which I also used to drive on track before this one.

I assume the Manthey aero addresses the front end grip issue?

Batattack,
Could you make an adapter plate that picks up the seat attachment bolts and use that ? How does Manthey do it?

 

[Mad Matter]

I'm assuming you have already adjusted your alignment, Maybe also lower the front a bit or raise the rear to get better front end traction. This can be done with adjustable front end links or software. And/or upsize contact patch of the front tires or downsize the rear.

 

[Batattack]

I don’t know exactly how Manthey did it, but I’m sure it also has multi-point racing harnesses, since at least the prototype/test cars were equipped with a roll cage as well.

I think I’ve found a ready-made harness bar for it.

 

[Batattack]

Thank you for the tips! We’ve already looked into many of these aspects and found that rear alignment adjustments are possible, but front camber cannot be adjusted using OEM components.

Are you aware of any proven suspension components for this car that would allow additional adjustment? I have to be careful with aftermarket parts, as a 2.3-ton car puts enormous loads on suspension components at the limit. In Time Attack, every corner is driven at 100% in pursuit of the fastest possible lap time.

I won’t be reducing the rear tire width. In fact, I’ve done the opposite, just like Manthey, increasing it to 335 mm. I’ll be testing both 21-inch and 20-inch wheel setups.

How can the ride height be lowered through software?

Just by lowering the car you will add front camber. I adjusted my rear camber with a special tool and the front was -1.7 after lowering. You will need it to be more aggressive.

I haven’t touched the alignment yet. What would be the best way to approach it? The Taycan doesn’t have any factory camber adjustment on the front axle.


Are there any aftermarket suspension components available for the Taycan that would allow for proper alignment adjustments? If so, could you share some links?


I also have a set of 305/30R20 semi-slick tires coming for testing on the front axle.

Disclaimer... My wagon is my "dad car" kid hauler so I have not tracked this car and cannot give out specific settings but I do have experience setting up other cars for the track.

From a general perspective, a little more toe out in the front and toe in the rear will help loosen it up and help overcome understeer.

while the caster or camber is not adjustable on our cars, only able to be shifted.
uou add adjustable end links or adjust the height with PIWIS this can help shift the weight balance towards the front by lowering the front and raising the rear to induce less rear grip and add more front end bite. This also has the added benefit that as you lower the ride height, negative camber increases so this will help add grip at the front.

you can also achieve front end grip by reducing tire pressure at the front and/or increasing pressure in the rear to reduce rear end grip.

Sorry I dont have any actual data on tire temps to know what is exactly going with the tires. so I cannot say you will or will not overheat your tires doing any of this.

How are you dealing with thermal limits?

 

[Batattack]

Thanks for the information. I’ll have to try adjustable sway bar end links and ask my Porsche dealer if they would be willing to lower the suspension below the OEM ride height. I only have VCDS available, not PIWIS.


Do you mean the battery’s thermal limits? It seems to start limiting power at around 55°C. The cooling system is good, but when the ambient temperature is above 25°C, it can’t keep the battery cool enough for more than 2–3 hot laps. By that point, my front tires are already approaching 100°C, so it’s not really possible to continue pushing hard for much longer. Even so, it’s still in a class of its own compared to other EVs.


In 15–20°C ambient conditions, I completed 11 fast laps at roughly 89–100% pace at Kinnekulle Ring in Sweden without any issues.

 

[Mad Matter]

I think I misspoke, I meant lowering links for the air ride suspension not sway bar end links. I dont believe they sell adjustable sway bar end links for the Taycan.
