Quaife ATB LSD - Anyone fitted one yet?

[longbow]

I'm busy playing around with different differentials on my VR4 Legnum which got me thinking about the BTR one in the Cerb. After doing some research, I've come to the conclusion that this will mostly likely be my next upgrade for the Cerb. It isn't cheap at nearly £850 plus fitting, but it should make the Cerb a far more predictable beast when applying power in the twisties. I've read that a few of the track Cerbs and TVRs have them fitted, with glowing feedback on tractability, but I was wondering if anyone had fitted one in their road going Cerb yet?
