I love my '62 Buick. Sooo much torque and sooo sexy lookin'.
For the longest time I could not get the thing to go 'round the Nurburgring without bouncing all over the track or developing nasty steering wobbles (further and further to each side followed by the inevitable fatal spin out). I upgraded suspension and Dif (though I like to leave it standard with no independent rear suspension and no LSD top maintain that old school feel). I spent much time tweaking the settings and adjusting the weight balance and still had the same problems whatever I did.
The solution came on me almost by accident. I pulled out all the mods (taking the car back to stock except for supercharger/ clutch/ flywheel/ driveshaft), and switched all the ASM and TCS down to 0. The car obviously requires a fair bit of throttle control due to the obscene torque (though I do like to overthrottle and light the rear end up, as the one tyre smoking effect is fun on the replays), but it no longer spins out or bounces around uncontrollably at speed on the bumpy straights.
It seems to me that the ASM applying the brakes, and the TCS slowing the drive wheel was actually CAUSING the car to become radically unstable under these conditions. More fine control is now required, but hey that adds to the fun.
Any thoughts on this?
