I'd really recommend you put your stock shifter back in or swap in a gsr shifter for kix. DC sports makes crap for parts, and almost everyone I know with short shifters have said something just isn't right.
You could look into a C's short shifter (big recommendations from some folks), but I'd say swap in your stock shifter, and use your polyurethane bushings. That's what I run and I couldn't be any more satisfied.
