Need help to lower my diff ratio

Homer · 11-14-2013, 01:36 PM

I'm running a 54 plate rx8 with a turbo Diesel engine in it about 300bhp but the revs are to high

So I'm after getting a lower diff been told that the rx7 automatic crown wheel and pinion will fit ?? Then it be 3.909 I think

I'm running standard diff which is 40 teeth crown and 9 on the pinion think it's a 4.444

Hope this is a better add second time lucky
