Kaaz Diff?!?!?!
Anyone running this in their Focus RS MK1?
As i'm currently sorting a Fast Road/Track Car, whats this diff like on the road?
I've heard it's better than the ATB, doesn't torque steer viciously and is a nice drive. However, I would like to hear opinions from people running them.
Much Appreciated!
Cheers

The kazz will be no different, its just that the gripper unit is uk built so easier for servicing etc.
Ive driven a lot of rwd stuff with 2 way plated diffs and really good to use, just in some cases a little noisy

If you read the Focus MK1 RS development info thread I posted on here, it mentions that It's more the suspension geometry that makes them torque steer rather than the diff alone. I've used Quaife ATB (and Peloquin, the US copy) in 200 ish hp Golfs and they don't suffer the same torque steer.

i didn't have twitching issues with my atb in my old mtx75 box, and i reckoned on over 400bhp with 2BAR through the gt3071r.
kaaz will just be better for straight line, not as forgiving in the corners though.

It's not a case of simply setting up the geometry, it's a design fault from widening the track on FRS from stock Focus.
As the (non-Ford) guy responsible for the RS calibration, the guy who developed the boost controller rework for the EEC and personally did all the boost control calibration, let me say again, the press cars were very close to standard production in this regard. I say 'very close' because from my feeble memory, I think we were still fine tuning the 1st and 2nd gear boost limiter so there may have been some very subtle changes on the final production calibration. I can't be 100% sure. The torque steer problem was, as far as I heard from people who likely weren't being very charitable about it, a geometry stuff up when the track was widened from the standard C170. The guy doing the design apparently held the scrub radius fixed, instead of the king pin offset. I'm not a chassis guy myself, but the kinematics of such a suggestion makes sense, although I'm sure there's always a compromise to be reached in all of this.

So will have everything setup correctly and see how I get on. Can't be too bad if others have set their ones up this way.
