On the money once again my friend I had a Quaife style R180 (4.8:1) in the rear of my Group G monster many, many moons ago. It was sourced through a contact in England who I used to get TR8 parts from. Anyway, if you didn't drive with 100% committed acceleration through each corner, the LSD would disengage, and then re-engage, usually quite violently.
This of course meant that if you went into a corner which started tight but opened into a sweeper, as you head in under brakes, LSD not engaged. Line the nose up and hit the loud pedal and BANG LSD engaged. Arse hangs out, hold on to her and hope your steering is quick enough to opposite lock it out of the corner. Great fun until you need to feather the throttle through the sweeper to hold the slide in that gear - once you backed off it would disengage and re-engage. To make a long story short what I am saying is - understeer, oversteer, understeer, oversteer etc etc. This also caused component failure both within the diff, and in the universals of the halfshafts. It was actually really similar to the older detroit lockers. They gave a spectacular, fun drive, but all that fun cost a lot of time. Clutch packs are hard to beat for reliability and predictability.

Apparently they ditched them due to licorice (transverse worm) gear failures. They also changed the handling characteristics (apparently unfavourably?). I notice the R34 GTR's had one as well (also S15 Silvia). For high performance applications they seem to go back to clutch pack diffs again ? Any one on list have any personal use comments???

This is very different from most limited-slip or locker diffs. Here's a report from a guy who put one in his BMW: http://staff.connect.com.au/lheather/318ti/1999-02/msg00573.html I got one from here: Amax Engineering Factory 6/19 Edlermaier St Bayswater Victoria Phone Max: 0418 485 460 [EMAIL PROTECTED] $1450 AUS dollars +GST NOTE: This is old info, price or availability may have changed. Ther are cheaper LSDs available and the price does not include the carrier, pinion and ring gear, just the diff centre. If you do get one tell him Rob from West Australia sent you.
