Thank ya bbandit & drft.
bbandit, it was pretty easy to use that car for, me at least. it was the first car that i didn't butcher the settings on. that's probably why. haha. i'll have to use the same basic settings with the other cars to see if that's what really happened.
if you want to try my settings, I bought all of the power upgrades, drivetrain, suspension. with the suspension, I left everything normal except the sway bars at 1, the camber at 4 and 3 (or was it 5 and 4), the limited slip I left the same other than the initial torque at 60. and simulation tires of course. I wish there was a stage 4 turbo for that car

it hits full boost at about 3000, but it dies off way too quick.
