B&M Short Shift Clunk

[Stunin_Stud]

Hey so Im happy overall with my short shifter, except it makes a clunk sound like it is hitting something when i shift to the top row or gears ( 1,3,5) and shifts are really hard and stiff. Im thinking this is because its an aftermarket unit and has metal components, but maybe theres a way to make it feel better. The bottom gears go in smooth. anyone have this problem? I tried adjusting the cables but besides making the throws slightly longer it didnt take the clunking out. I was thinking of trying the undercar application. I would appreciate everyones feedback.

thanks
