IAG and Exedy have partnered to create the IAG Spec Exedy Triple Disc Clutch, engineered for high-powered 2004–2021 Subaru STIs equipped with modified 6-speed (T56 / 26 spline) manual transmissions. Designed for street and track use, this clutch handles an impressive 923 ft-lbs of torque—over 150 ft-lbs more than the standard Exedy FM023SB—providing the ultimate balance of drivability and performance.
Features:
- For Modified Transmissions Only: Compatible with 6-speed T56 / 26 spline transmissions. Not compatible with OEM 24-spline input shafts.
- Triple Disc Design: Increases torque capacity and heat distribution for reliable power transfer under extreme conditions. Some rattling is normal when the clutch is depressed or in neutral.
- Cerametallic Clutch Discs: Designed for high-heat, high-performance driving, ideal for racing or repeated aggressive engagement.
- Pull-Type Throwout Bearing: Uses the OEM STI pull-type bearing and slave cylinder—no conversion to push-type required. Includes throwout and pilot bearings.
- Rigorously Tested: Proven in record-setting VA chassis STI drag cars, capable of repeated 8-second passes with a smooth, linear pedal feel.
- Transmission Compatibility: Works with upgraded T56 / 26 spline input shafts; pairs well with the PPG V2 1st–4th Drag Gear Set for enhanced durability.
Included:
- (x3) Cerametallic Clutch Discs
- (x1) Anodized Aluminum Pressure Plate
- (x1) 4140 Steel Lightweight Flywheel
