Swapping 1 way LSD for factory, S5 car with an S4 tranny which diff will fit?
Currently have a 1 way mazdaspeed LSD which seems unrealistic for daily driving on turns so I'm planning on putting a factory diff. This is a 1991 S5 car which has an S4 T2 tranny... do I need an S4 or an S5 rear diff? or either will fit?
