Got the car Dyno tuned yesterday and was finally able to do some hard pulls on the road. At about 50- 60mph under full throttle the car develops a SEVERE side to side wobble from the rear. It is an open G96-01 transaxle. I checked the rear toe and its about 1/64 toe in. Everything is tight and show no signs of wear. The car has 900 miles on it. Has anyone else experienced this? Rear bump steer on hard accel? Suggestions?
