Transmission

A gearbox that shifts crisp and fast is noticeable in every gear. In this category, you'll find short shifters, differential parts and gear ratios, flex discs, clutches and flywheels, and stiffer transmission mounts to eliminate slop.

All short shifters are on one page, with models for BMW, Nissan, Toyota, Mazda, Subaru, Honda, Hyundai, Porsche, and more brands. They shorten the throw of the gear lever, and most can be installed without modifying the car. For the differential, you'll find solid bushings and axle kits for many rear-wheel-drive cars.
