IAG Spec Exedy Triple Disc Clutch for 2004+ Subaru STI 6-Speed


The IAG Spec Exedy Triple Disc Clutch was developed in a collaborative partnership with Exedy, known as the undisputed world leader of performance sports and racing clutches. This specially designed clutch was engineered for high-powered 2004-2021 Subaru STIs with OEM 6 speed (24 spline input shaft) manual transmissions. While this clutch is streetable, it has the ability to handle an impressive 923 ft/lbs of torque, which makes it ideal for track days, drag racing, or just straight-up aggressive driving. This torque rating is over 150 ft/lbs higher than the standard FM023SB Exedy triple disc clutch. The IAG Spec Exedy Triple Disc Clutch is the perfect balance of street functionality, combined with the capacity to stand up to high-power modified engines.


The stock Subaru clutch is equipped with a single disc, which is sufficient to handle the lower power output of an unmodified engine. Engines with significant power upgrades require a more powerful clutch that can take on considerably higher torque and heat levels in comparison to the OEM version. The three-disc design in the IAG Spec Exedy Triple Disc Clutch effectively triples the overall grip and increases power transfer efficiency without slipping. With three discs to share in the torque load and heat distribution, excessive heat issues that can lead to clutch fade and reduced performance are eliminated. Please be aware that some level of “rattling” noise is expected when the clutch is depressed or the vehicle is in neutral.

IAG Spec Exedy Subaru STI Triple Disc Clutch - Cerametallic Discs


The IAG Spec Exedy Triple Disc Clutch features the use of cerametallic clutch discs that are designed to withstand the rigors of performance usage better than organic clutch discs. While organic clutch discs can handle a bit of spirited driving, they will eventually overheat. Cerametallic discs are designed with the ability to absorb more heat, making them ideal for racing situations where repeated engagement and disengagement can boost temperatures.


IAG’S Spec Exedy Triple Disc Clutch incorporates the use of the OEM Subaru STI pull-type throwout bearing and slave cylinder. STI models come equipped with the pull-type slave cylinder from the factory, so upgrading to a multi-disc clutch generally means that you also have to convert to a push-style slave cylinder. The IAG clutch kit does not require converting to a push-style slave cylinder. The clutch kit also includes the throwout bearing and pilot bearing, unlike the standard Exedy FM023SB clutch.

IAG Spec Exedy Triple Disc Clutch for 04+ STI 6-Speed


We have rigorously tested this clutch in our record setting Subaru VA chassis STI drag car. This clutch has lasted an entire season with plenty of life left while supporting multiple 8 second passes. With a linear clutch pedal feel that makes drag launches easy, and the ability to hold significant power, we’re confident that this is the best performance clutch ever offered for the Subaru STI.
