Quaife ATB Helical LSD differential for 2002-2010 Gen 1 & Gen 2 MINI Cooper S equipped with a Getrag 285 6 speed manual transmission. This unit is a direct replacement for the standard MINI open differential. Installation of a Quaife ATB Helical LSD differential transforms your car’s performance.
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.
This differential has many benefits over a standard open differential, including maximizing traction and minimizing wheel spin, 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.
Quaife differentials are 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.
The Quaife ATB Helical LSD differential is second to none and is proven performance "must-have" for serious track day, autocross and time attack MINIs. Accept no imitations! Quaife ATB Helical LSD differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment.
