ive got a quaffe mate, difficult subject really, i went for a quaffe because it comes with life time warrente, with any bhp!! but the quaffe part is only the lsd , it gets rid of the week planet gears on the standard diff which are 90% of the time what breaks, even with a quaffe there is still a slight chance that could break the pinion gear or smash the casing.. but if that happens i will just break up one of my other 4 broken diff and swap them over!!
The crown and pinion gears and casing are worth less, as nearly every 2wd cossie owner will own a couple of blown diffs at the back of the garage they dont want!! lol
