Limited Slip Differential 987.1 Cayman S / Boxster S - 6 Speed - Quaife ATB Helical LSD - 20-80%

The Quaife Automatic Torque Biasing Helical Limited Slip Differential allows your car to accelerate quicker and corner faster by providing consistent power to both drive wheels. It is a direct replacement for the standard open differential, and unlike the standard open-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 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 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.

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 250 applications - the Quaife ATB Helical LSD differential is the best option to utilize your cars performance. Quaife ATB Helical LSD differentials are used by many large manufacturers as original equipment.
