95 Formula: I get a severe body jerk to the left feels like about a foot when trans shifts to 2nd I can hear what sounds like LR. tire hitting body. When I was using the stock 16in. tires they would break loose, I changed to 315-35-17 on back, now they grip instead of spin, I have a hard shifting trans. shifting at 6700 I changed the shift to 6300 trying to stop the jerk to L. I have checked the Panhard and LCA's can't see anything bad. I must find prob., almost put rear of car in other lane yesterday. When I shift at 5500 just puts you back in seat but don't act crazy, am I overpowering chassis or what. My 94Z m6 has much more HP and don't do this with same tires and wheels. Any one know whats wrong. I gotta fix it. Danny Mc
