9" diff,how bloody much.Well that's out the window then.I'm looking for something to cope with 500bhp probably 450lbs/ft torque at least.I was contemplating just getting my standard diff rebuilt as the car won't be tracked,launched or driven that hard on the road.The planet gears shouldn't break if it's not launched should it?
So u think I should contact MIKE R then to see wht he has for a 7.5" diff?Like I say I don't wasnt it noisy and clonkey like a grippa diff.What size are the Quaife diffs and Grippa diffs anyway are they still standard 7.5" size?

Thanks.Lee.
