Anyone using a Quaife ATB diff?
There have been a few recent threads on the merits of LSD's but I'm interested in experiences of a Quaife ATB in a 7 as the
characteristics would appear to be less detrimental than other types.
Is there much involved in fitting one in a sierra diff with drum brakes?
I believe that Wadders is about to use one.
Cheers,
Colin

Used one in a pug
I have used a Quaife ATB in a peugeot 309. If you did not know the car had the diff in it you would not know it was there. The only difference being
that the front wheel inside does not spin up when applying power mid corner. They are not so snatchy asplate LSD's. Both tyres have to be in
contact with the road for the diff to work, if one wheel is in the air you will loose drive. Both wheels will spin if you apply too much power.
In the Pug you take the existing diff out of the gearbox, take the crown wheel off put it onto the diff. put the diff into the box and set the bearing
preload.
Not quite the info you wanted but maybe of some use.

i seem to recall the catherham boys rate the ATB diff ........... but, IRC they've killed them by going over the curbs repeatidly on the race
track. Something about that wheel going in the air, then landing lots of times causes them to, sort of, fail.
Shouldn't be an issue on the road and the road boys don't seem to complain.

I have one on my Super 6 in a cortina axle (only cost £250 new from tiger  they only had a limited number in ), simple to fit just use a torque
wrench, not a problem.
same as fitting the peugeot one just unbolt crown wheel and bolt into diff.

Hi colin
sadly my 3.14 with ATB is still sat on the bench, so i can't comment on the performance. Still need to sort the drive shafts out, in your case
it should be a simple swap as i guess you already have tripode shafts with a drum set up.

I've fitted one to a mates hotrod race car. I was well impressed with the engineering but we could never get it stop understeering in the
cornerswhen it was wet. It seems that there is a definite locking point (ie it locks solid and want's to push on forward).
He said he'd discussed it with a guy at the autosport show and it does seem to be a problem area (allegedly).
It was a nice bit of kit though and off the line in the dry it was a lot quicker than any of the plate types. I reckon he made up 5 or 6 yards on the
standing start most times.
