FM022HD

The EXEDY Twin Cerametallic Clutch Kit for the 2004-2021 Subaru STi models is a great clutch if you are both a drag racer and drive your car on the street. The pedal is firm and easy to engage making it one of the most recommended street/race clutches out there! The SD version is good to 450 WHP and the HD is designed to handle more launches and good to 550.

What's the difference between the Exedy SD and HD?
The Exedy twin clutch comes with two options - HD or SD. The difference lies in the pressure plates. SD is the "Standard Duty" and can handle up to 450 WHP. HD is the "Heavy Duty" with more clamping force designed for drag racing and launches up to 550 WHP. Both versions have about the same pedal feel.

Why do I need a twin disc clutch?
Multi plate clutch kits (Twin & Triple Disc) simply put have more than one clutch disc. The stock clutch comes with one disc and by having two or three discs, you essentially double or triple the surface area to be clamped. If you are like most STi owners, you have probably doubled or tripled your power... so you need to compensate with a more powerful clutch. There will also be intermediate plates between the discs and especially with the Triple kits, when you push in the clutch pedal, you'll hear those plates rattling around free. That's totally normal and fun to mess with your friends.
