Our advantages

IT IS HERE! Built for performance! Built for you!!

The Audi S1 Sequential gearbox is the product that Audi quattro drivers have been waiting for all these years! With a torque rating over 800NM, there is no product close to matching the craftsmanship that Kotouc Gearboxes can deliver. 

The original Audi 01E gearbox is replaced with the beefed up Subaru STI 6 speed gearbox. Installed into the STI casing is the Kotouc Gearboxes R4 sequential gearbox kit, and additionally supplied is the engine flange, axle CV joints as well as the rear output flange so that the original components can assemble. Specialist drop gears are also suppled with a new ratio.

To suit the Audi clutch, supplied is an uprated input shaft that is produced in 2 pieces which aids installation.

Kotouc Gearboxes has also produced a holder for the Tilton hydraulic clutch release bearing which is quite a common upgrade amongst the Audi community. 

Many thanks to Rene, Klaus and Karl.

All parts are ISOTROPIC SUPERFINISHED!
