Quaife Engineering's automatic torque-biasing limited slip differential for the front axle of the 2009+ Nissan R35 GT-R.
Instead of waiting for wheelspin like a clutch-type LSD, the Quaife ATB continuously biases torque to the front wheel with the most grip. The result is stronger corner exit, less understeer, and no wear items to service.
Pairs naturally with the Boost Logic billet front differential case for cars putting serious power through the front axle.
