Ok I have run into a little problem the stance on my rx7 is al most complete but the rear wheels are sunken in but the front is hella flush.

so I have two choices I could either adjust the camber in the back to make it flush with the body or do wheel spacers.

now the only problem with that that I have is that I know that increasing my rear tire width will cause under steer. and it is already a under steer happy ride. but if I dial in more positive camber will it make my car over steer like crazy. (it would be more controllable) I am just really stuck and don't know which to do to fix the problem
