im curently building my own g/box using low millage gears and a 3.82 lsd
for my 242bhp rst ive had the casing machined to accept the ib5 bearing and its been pressed on to a non machined pinion shaft.basically im not sure this will hold as my old unit sheared of the pinion in 2k of running.
cts etc etc are way to expensive
just want to no wot boxes sum of you run or no a way
as scs tell me anything over 17psi you will come across probs with them so surely we are all in the same boat thanks
