First I will give a small rundown of my car and what is done to it before I describe the problem. I have MM subframes, Pro3I lowers, and 10.5 Bullits with BFG 315 drag radials.
Well my problem started after about 12 hard launches on the streets with the new BFGs, talkin heating them up and then droppin it at about 5 grand, let me tell you these things hook. The last time I dumped it and hit second I heard a loud thump and the car felt like it pulled to the right hard, it repeats itself everytime I do this. It feels like someting is hitting right under my feet.
I have checked everything under the car and cannot find it. Checked the lowers, rear sway bar, even if the exhaust was hitting somewhere. I have tried jacking the motor up to see if one of the mounts is bad, but they all look good, even the crossmember looks fine. Sorry for being so long but I am at a loss, and may have to take it to the dealer. Any help would be appreciated.
