Stuff started coming unglued on my car when I hit the 11's. The motor started yanking the spot welds loose in the shock tower to motor mount bracket area. I also found some sheet metal buckling inside the car around the rear fender wells. I don't have subframe connectors installed(yet). I don't have a cage either. Something else that I have noticed is that the driver side door makes a kathunk sound for a day or 2 after I race.
