Quaife Limited Slip Differential for Toyota GT86 & Subaru BRZ - Refurbished

Since their introduction in the 1980s, Quaife ATB limited-slip differentials have established themselves as a benchmark thanks to their performance and reliability. Precision engineered and manufactured in England, they are used worldwide in rallying, circuit racing, and Time Attack competition, as well as for everyday road use.

Unlike traditional plate-type limited-slip differentials, Quaife differentials use helical gear technology. This system offers many advantages, including smooth and quiet operation, no harsh engagement, reduced torque steer, and the elimination of differential lock-up effects, all while requiring no specific maintenance.

The operating principle is simple: the Quaife differential automatically transfers torque to the wheel with the greatest traction. On front-wheel-drive or all-wheel-drive vehicles, this helps reduce understeer, while on rear-wheel-drive vehicles, oversteer is minimized for improved traction and stability.
