well i tried that tune out and used the gt world championship for testing
i thought the rh adjustment was interesting and a good solve for the 49/51 weight distro which was probably causing a lot of that snap oversteer. i felt that it was a bit much though so i set it at 65/60. the transitions into and out of corners was a bit odd too so i increased the front camber and i also did a bit of playing with the dampers. the brake setting is spot on, for me.
anyway i tweaked a few other things and got it to really run well. the way i have it set now its REALLY fast and tremendously quick in every part of a track, but it is a bit tricky in the high speed stuff when you suddenly come on boost with the high rpm turbo. the best solution i have for that is either more traction control (not the best idea) or longer gearing, and i think gearing is the answer, but it has to be some specific tuning of the 3-4-5 gears. that would be a set up specific to max power on this car
so yeah no one probably read that because i'm a huge nerd.
here's my final settings for it (for now), super fast, a little bit demanding but nothing like the insanity of the stock settings
suspension
65/60
16.5/18.2
4/5
4/5
5/5
1.4/0.5
0.02/0.15
brakes: 4/1
trans: auto set to 255 mph
lsd no tweaks (could def be turned up)
max aero
i think there's a fair amount to be got out of the dampers and roll bar settings as well as the lsd and some fine tuning of the gearing, at least for max power set ups. this car can be REALLY REALLY REALLY fast if someone takes the time to really go through it. the game is still pretty new to me though and so many cars i haven't played with yet, so i'm not gonna fine tune this for a bit.
hopefully someone else runs with it because this car is really potent, it just seems they've bottled up the potential a bit.
