OS Giken STR Twin Plate Clutch - Mitsubishi 4G63 Evo 4 - 9SKU: MT031-BJ5
The OS Giken STR Clutch was designed to hold high capacity power while still retaining a relatively light clutch pedal.
This technology was driven from our racer's demand for a lighter clutch during long endurance races in Japan. Heavy clutch pedals lead to driver fatigue during long endurance racing. Matched with a unique clutch cover which allows for factory like clutch pedal feel.
The OS Giken STR series clutches are designed to offer much higher torque capacity than a normal clutch, while retaining drivability very close to standard. By using special new plate and diaphragm designs, OS Giken have achieved ample power handling with just 715kg clamping pressure. This makes the STR series perfect for every-day driving applications, along with most race and drift applications.
The clutches come complete with light-weight chrome-moly flywheel, ruby red-anodised billet aluminium clutch cover and the required bearing/carrier set or pull-push converter kit where required. We do not recommend this series for dedicated drag use. They are suitable for up to 550hp at the engine.
Note: for this model the plates are solid (damper springs shown in photo are not used in this particular model).
