Currently delving into the Porsche expansion. Doing some experimenting with the GT3 RS 4.0 and i cannot get the front end to stop lifting under power ( particularly bad accelerating out of corners). Any ideas? Stiffen rear suspension perhaps?
I’ve got the same problem, and had the same with the Daytona Prototype (used someone’s tune for that car specifically designed to keep the front down) Also have similar problems, albeit less noticeable with the Ford GT40
i have my suspension set to 700 rear and 600 front and softened the front roll bar and that helped, It could improve more though and I’m still experimenting with it.
Thank god, I thought it was just me. I tried running it on the Nordschleife and got bucked off the track multiple times when I hit small bumps. I even have the adjustable front aero with full downforce.
Had a similar issue. My advice is try tuning at spa. As it’ll happen alot. So if you can get it driveable there then it’s ok most places.
I found softening the front springs and ARBs helped alot along with lowering the front one from its ride height and raising rear one
The RUFs in Forza 5 did this lot as well.
Like most have said here.
Run soft front ARBS and stiff rear ARBS.
You can tune grip in with the springs
Thanks for this tip. Will give it a try.
Well I thought I would try this car out.
- Im not sure if I built up the right one now that I think back on it. Its the one with 970 or something rear downforce
- I wasn’t having much of an issue after throwing a few changes at it. It is by no means a finished tune but I was able to drive this car around spa and prague with no issues and I don’t drive R class ever. This is my first tune up there. If this is the right car then it should at least get you guys close to what your looking for. If not I will build up the right one after work today and post if for your
Open source for the OP (if its the right car lol)

Some of the setting might even be stock as I was more or less worried about front end lift off but I didn’t get any of that just on throttle understeer slightly but that’s normally a Porsche thing so I just waited another .1 of a second before smashing the throttle and problem solved.
Again I hope this is for the right car if not I will get that opened up to you guys later today when I get off of work
They meant the rs 4.0, the turbo seems pretty stable (970 lbs on the back wing!?)
Why not raise the rear, drop the front to transfer more weight over the front, then run a softer rear Spring, boost the bump to stop it squatting so much that it’s lifting the front…
Use the damping on these cars guys. I’ve not had the pleasure due to finances (motorbike comes first).
Use the damping and ride height to transfer the weight and deal with pitch…

So I put this together and it has no wheelie issues. Like the other one the tune is very basic so there is a lot to improve on but this should help you get started on your quest.
Porsches (rear engine cars) need a different driving style then mid and front engine cars.
I’ve only noticed this in the 2012 GT2 RS (that thing is a rocket) doing career (so stock) it’s accelerating so fast the small bumps make the front get light. Very evident on monza. Inbetween chicanes accelerating around the bend. maybe less bump or increase as its to sloppy?
I was destroying AI so I I just lived with it. It wasn’t terrible. Just had to back off 100% throttle at times. But I thought about adding height to the rear, and experimenting with bump and rebound.
I was really just pushing through career so I didn’t really look into it. But I think I wanna come back to that car for accel track experimentation. Something real fun about that car. It had a nice seat of your pants feel.
(I think once you build up and add aero it would go away- but I really don’t know)
