This combo gets you the Kartboy short throw lever PLUS (now you see where the plus comes in) the front and rear 5mt shifter stay bushings for your Subaru.
Be sure to pick the correct lever for your car. All 02-07 Imprezas with the standard shifter need the 02-07 wide-style Kartboy lever. All 02-07 Imprezas with the Factory 5-speed STi Shift kit should choose the 97-01 narrow-style Kartboy lever. Obviously, all 97-01 Imprezas should choose the 97-01 narrow-style Kartboy lever.
