Cant help with a brand but can give you a little insight into what im running.Starting with a seized Crown diff,DB had to press all the spider gears off the shafts cleaned them up then I coated everything with "wettable"coating.My understanding of super diffs is that installing a super diff reduces the oiling which can lead to gears seized onto the shafts or like daimo Pell chewed out axle spades and fulcrum plate(of no concern to you just saying),haven't done many burnouts but getting up near 80,000miles so far.will be changing the diff gears soon so DB will be having a look soon.Craig I probally spent $400 coating all the gearbox internals and every part was 2nd hand,It's the sweetest box.Clutchless downshifts which would be good for circuit racing if you left brake!Come see me for a free demo at the Sydney event.
