im fitting a different gearbox and rear diff this coming saturday as 3rd is startin to crunch a bit is there anything else im going to need to change at the time im going from a uk box to a wrx i know it will have less top end

 

yes the rear diff will need to changed to suit the box your fitted and depends on what year box maybe the rear drive shafts also
