ACT Releases SFI-Certified 240mm Upgrade Performance Clutch Kits for the 2006-2015 Subaru WRX

LANCASTER, CALIF., Apr. 26, 2016 — Advanced Clutch Technology (ACT) has released a new 240mm conversion kit family for the 2006-2015 Subaru WRX. SB11-HDSS

This new upgrade kit has allowed ACT to utilize a 240mm disc instead of the original 230mm included in ACT’s SB5 clutch kits. ACT’s 240mm upgrade kits provide more heat capacity, lower pedal effort, and a more efficient pressure plate design for better overall feel and drivability. By designing a more efficient pressure plate, ACT has also been able to make an Xtreme version for the WRX 5-speed applications. These Xtreme pressure plates offer 21% more torque capacity than ACT’s previous SB5 kits.

The ACT Street clutch kits combine one of the pressure plate choices with a performance organic street disc. The disc features premium organic friction materials able to withstand increased heat and abuse, steel-backed linings for highburst strength and modifications engineered for quicker shifting. The ACT Street clutch kit provides a moderate and consistent pedal feel, smooth engagement and significantly improved durability. These kits meet SFI Spec 1.1 and have increased torque capacity up to 510 ft.-lbs.

The ACT Race clutch kits combine one of the pressure plate choices with a cerametallic Xtreme Race disc, which is available in 6- and 4-pad spring-centered and rigid-hub designs. These discs are highly durable while allowing for quick shifting. The Xtreme Race discs are for high-powered engines and recommended for track use only. The ACT Race clutch kits meet SFI Spec 1.1 and are rated to hold up to 650 ft.-lbs. of torque at the crank.
