Sounds a bit useless if this is the case - and from what I've read I know Quaife's aren't useless. I certainly understand clutch type LSDs but I'll have to read up on helical units it appears.

With my open diff there are times when I turn into my steep/sharp driveway & I've got one rear wheel in the air and no traction, even with the e-diff trying to do it's thing. I then have to reverse back and get a run-up. At the track the e-diff thingy has overheated the rear brakes and brought up a dash alarm.

Still looking for a cheapish way to get hold of an LSD for my welded diff type manual 135. Can source from Andrew for ~$4.5k + freight each way + fitting. Can source cheaper from the US but looks like I'd also need a new tailshaft as I'm told the US diff is different from ours. Anybody else with a manual 135 been down this path?
