Has anyone tested much with the Gear Diff? back to back with the ball? Got my car fairly well set up on my local track (tight technical low, to med grip asphalt, outdoor). I've ordered a Spec R diff, along with some 1000w oil, apart from the lower maintenance, which I'm not overly worried about, any advantages? running Mod/Open. Will have it before my next race meet, but I'm not able to test before hand, just wondering if its worth the punt to just put it in.
Cheers
