OS Giken Grand Touring Series Clutch (04-21 STI)
$2,090.00
SKU
osgSB041-BQ6
The Grand Touring Clutch is our latest development to our clutch lineup.
The GT2CD clutch utilizes dampened hub clutch discs for added drivetrain protection for those high horsepower builds. We combine our race technology in addition of our unique floating pressure system to provide a smooth and chatter-free driving experience. This is ideal for those customers looking for a higher capacity clutch for their showcase vehicle to take it to and from their local concourse gatherings.
CLUTCH COVER
Our specially designed clutch cover contains a unique leverage mechanism for the diaphragm spring, resulting in a higher clamping load of the clutch disc(s) while also reducing pedal effort. These diaphragm springs combined with our special OS Giken Release Sleeves provide a much easier to operate clutch.
DISCS
We utilize full face metallic clutch plates to achieve high torque capacity from our clutches. This allows for us to use much softer diaphragm springs to achieve equal or better torque capacity compared to our competitors with substantially less pedal effort.

CLUTCH HOUSING
Integrated ventilation holes reduce heat generated inside the clutch system and allows for friction plate dust to exit outside the clutch system, thus increasing reliability and safety. Both the clutch housing and flywheel are chemically heat treated to handle extreme conditions. Increased power output typically requires more torque capacity(friction) in order to hold. This often leads to more heat being generated
FLYWHEEL
Our hardened steel alloy flywheels provide superior durability and life than aluminum flywheels, which also results in quicker and predictable engine response. We develop our own flywheel design to maximize our design and engineering philosophies into a no-compromise, complete clutch assembly.
Our integrated clutch and flywheel packages increase transmission efficiency and engine response. Our clutches and flywheels are built within strict tolerances and crafted using carefully selected materials to provide the highest quality and durability.
