Quaife ATB helical limited slip differential. Very little use - only one autocross and the rest was boring DD duties.

Purchased from WMW ($965 +shipping) August 2013; professionally installed September 2013; removed January 2014. Selling because I'm selling the MINI.

The bearings are already pressed in, so it's plug-and-play!

$850 shipped.

Info from Quaife's site:

Unlike a conventional plate-style limited slip differential, the Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.

The Quaife ATB Helical LSD differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.

The Quaife ATB Helical LSD differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.

With over 170 applications, the Quaife ATB Helical LSD differential is second to none. Accept no imitations!

 

How much was it to get it installed?

 

PM on the way.

 

Payment Sent!

 

I paid about $1000 to have mine installed. (just another data point)

 

Does Quaife LSD really eliminate torque steer on R56s?
The listing of LSD characteristics by OP does suggest this, and I wonder whether those of you that have the Quaife did actually notice this especially in the R56s as a DD (spirited). Does it reduce torque steer somewhat? Does it eliminate it?
Torque steer is the one thing I really dislike about my new R56s compared to my old R53s.
TIA!

 

Eliminate? No. Reduce it, a little bit.

I find that torque steer is really only a problem when you are trying to haul *** starting off from a stop, or very low speed turns.

There was a bigger reduction when I changed the springs and shocks.
