P516 TOURING CAR GEARBOX
The P516 gearbox is a high performance front wheel drive touring car gearbox that was designed specifically for the World Touring Car Championship.
The P516 makes use of reduced center distance F1 derived gear ratios to minimise the size and weight of the gearbox and to minimize inertia. The gearchange system incorporates the latest polynomial barrel track design and low inertia gearchange rack to improve gearchange response and driver feel.
The low positioning of the gear cluster enables easy removal from the car under the chassis rail, and lowers the centre of gravity. The gear cluster is fully exposed when removed from the gearbox allowing quick inspection, and easy access for ratio changes.
