I was looking into Quaife and Grippers until Tony told me about the Supra ones so I'm going for one of those!!
I want to do it properly first time round, can't be doing with keep breaking and forking out for diffs all the time.
Many people see a replacement standard diff as a cheap option but when they've broken 4 or 5, it would have been far easier and cost effective to go for a proper one in the first place!!
