Clutch kits:
The clutches are able to withstand a substantial increase in power yet remain easy on the foot. The billet aluminum cover saves weight while providing a more direct clutch pedal feel, but still maintains ease of engagement due to the unique leverage mechanism of the diaphragm spring. Available for GTV, GTA, Spider, Berlina, Giulia & Alfetta. Both single and twin plate versions depending on application and engine torque output.

Transmission Short Ratio Gear kits:
A good race car build should start with the proper gear ratios and a strong gearset. Planning this first is often done before the motor build. With the 4cylinder nord engine getting the power to the wheels is always paramount in optimizing your track car. OS Giken has crafted a 5 speed kit for all 105/115 GTV's and for GTA's. High quality forged raw materials are hard shot peened for increased strength and longevity. All gears are helical-cut to maintain a quiet and smooth gearbox, allowing use on the street or the track.

Limited Slip Differential:    
OS Giken uses the plate type system for the best power delivery available to Bertone 105/115 GTV owners. Tested on tracks around the world this is a perfect way to keep the power down in your fast Alfa.
