It works from 1% throttle basically, as soon as you touch it. Because it doesn't "engage" as such.

It transmits torque from a spinning wheel, to a wheel with grip, so you always get power going to the outside wheel when cornernering, helping you turn in.

Sounds great right.

Problem is, in a straight line, it can only multiply the torque from a spinning wheel, I.e of you get a wheel on the grass / kerb where there is very little grip, it multiplies by (for arguments sake) 0. 0 x anything is always zero.

A diff which can fully "lockup" gives you effectively a solid (or getting towards anyway) axle. This means, no matter what grip the spinning wheel has, or hasn't got, the other one will always have torque on it.

Its horses for courses really. Dont get me wrong, I love my ATB, the way it just finds grip mid corner and actually tugs you into the bends is amazing.... I just can't help thinking if I had gone for a locking diff, it would have been even better on track.

That said, many many laps of the nurburgring, no wheel spin, and no rebuilds ever required
