9" or 12 bolt???
, spec 3 clutch.....and i need to fix that burning of the oil problem to before i do this....but i KNOW that 10 wont hold that on my M6..lol im surprised it hasnt started to whine yet( oh gah knock on wood)....just wandering what would be better....i heard that the 9" is kinda hard to turn at slow speeds....but on the alternative ive heard people say that they cant even hear their damn radio from the whine in the 12 bolt...so opinions are welcomed
