Topic: Looking for soild info on medium case (188mm) bmw differential
Ive been looking for info on changing ring gears and this is what I found. 3.07 and numerically lower numbers are all interchangeable and 315 and numerically higher gears are all interchangeable. From what I read, you can cross this threshold by adding or removing shims.(between the ring rear and the carrier) What I am trying to do is go from a 346 down to a 279, does anyone know if this would require adding or removing said shims??
Thank you, Dave
