Agreed... when the physics aren't bugged. Right now the physics engine is riddled with bugs and 9 cars out of 10 want a high ride height even though it makes no logical sense. Like you can't use real world physics and tuning principles in GT7 since something is terribly wrong with the modeling. It is being covered-up with downforce (check any of the 50's roadsters like the Aston DB3S, D-Type, etc to see how broken the physics are since there's no way to add downforce as a band-aid)Hi Pizzicato @Pizzicato1985
Ride height is strictly dependent on the car you are tuning but a general rule of thumb, and extreme oversimplification is that lower ride height gives stability of load transfer, whereas higher ride height gives grip.
This car has issues with load transfer, rather than grip.
Also, the oversteer under heavy braking is very easily fixed. It has nothing to do with spring uniformity, if you try that, you will likely make it worse!
The way you fix that is brake bias and, more crucially, softer rebound on rear. The reason you get heavy braking oversteer is the load transfer to the front, and making front bump stiffer will open a can of worms... so the easiest alternative is softer rear rebound.
Hope this helps your understanding of basic vehicle dynamics!
In the end, there is a reason I have tuned the car that way and I will be quite surprised if any improvements are easily done. Though you or anyone else is more than welcome to try! 🙂
After waiting some time for someone to try it for themselves too, I eventually came to something similair by accident lol not knowing the physics well at all. I just found a softer rear, especially the rebound as you say, helped tremendously. Your tune is perfect though, the car actually drives like a normal vehicle now it’s kind of insane. Tried your tune with higher power too, and it still handled it, although not as well of course. Thank you my friend 🙏Of course.
This is a highly difficult car to tune and I am not surprised no one from the regular tuning "gurus" was capable of taming it.
So I sat down myself, even though I don't really have the time and the result is below.
Drives like a charm, you might forget it's a RR Porsche!
Edit: brake balance is -2 (more on the front).
