I had major tweek issues with my car too when I first got it and so did every other driver at my track.
The problem is that Xray drilled the holes in the top deck so damn large that there is so much room for play. So the top deck would shift. Everytime I would hit something. The car would spin out in one direction. Immediate sign of a tweeked car or major chunks in one of your foams.
The best fix of all was the Team Pickles top deck. NO MORE TWEEK ISSUES..
The top deck is awesome. When you put the screws into the top deck they actually thread into it so there is no slop in the top deck to tweek the car...
