I don't care for comfort...prefer strength.I have a solid rear center bush, factory bolt and all other bushes stock, yet broke a inner LHS CV changing into 2nd with MT's.BA or BFBF has rubbish front bushes. Definitely change the front bushes to solid. Change the rear bolt to the highest grade you can, at least 12.9. This will increase the fatigue resistance. The diff bolt is a lever, if only it was supported on the other side.CVs can be an issue. Some people have luck and some dont. Obviously they work best when exactly horizontal. The cage is cast, billet is the go. Our Nizro car has billet CVs. I think people have also snapped half shafts, but I am not sure where the weak point is.

I think people have also snapped half shafts, but I am not sure where the weak point is.Can't comment on the nizzer billet cv's but stock units are strongest the the axle shafts is pointing downwards towards the hub slightly. Having them horizontal puts pressure on the cages and forces the ball to run outside the correct track. Having the axle angled downwards shortens the axle slightly due tonthe geometry in the rear end. Link to comment Share on other sites More sharing options...

I'd be too embarrassed to show that if it was mine.I never met the guy I got that off but it certainly takes a special kind of guy to get it to that point.
