Spec Exedy Triple Disc Clutch Kit

The IAG Spec Exedy Triple Disc Clutch Kit represents a collaboration between IAG Performance and Exedy, a leader in clutch technology. This kit is specifically engineered for high-horsepower 2004-2021 Subaru STI models equipped with the OEM 6-speed manual transmission and a 24-spline input shaft. It is designed to offer a balance of streetability and robust performance, capable of managing an impressive 923 ft-lbs of torque, exceeding the standard Exedy FM023SB by over 150 ft-lbs. This makes it an ideal choice for applications involving aggressive street driving, track days, and drag racing. The triple-disc design is crucial for distributing load and heat across three cerametallic clutch discs. This not only dramatically increases grip and torque capacity but also enhances power transfer efficiency and minimizes the risk of clutch slip. The increased surface area helps prevent excessive heat buildup, reducing clutch fade and ensuring consistent performance under demanding conditions. It is important to note that some rattling noise may be present when the clutch is depressed or the vehicle is in neutral, a common characteristic of multi-disc clutches. The use of cerametallic clutch discs offers superior heat resistance compared to traditional organic materials. These discs are built to withstand extreme temperatures generated during repeated engagement and disengagement, making them highly suitable for high-performance driving and racing scenarios where sustained high-load conditions are common. A significant advantage of this kit is its compatibility with the factory OEM Subaru STI pull-type clutch system. Unlike many multi-disc clutch setups that necessitate a conversion to a push-style slave cylinder, the IAG Spec Exedy Triple Disc Clutch retains the factory pull-type throwout bearing and slave cylinder. This simplifies the installation process and maintains OEM-style clutch operation. Furthermore, the kit includes both the throwout bearing and pilot bearing, which are not typically included with the standard Exedy FM023SB clutch. IAG recommends professional installation for this product.
