The Exedy Stage 1 Organic Clutch Kits use only premium friction materials that are resistant to slippage and burst. This clutch will have a slightly stiffer pedal than stock and will handle lightly modified builds. Great for a daily driver under 450 HP that might see a few passes at the track.

Vehicle Fitment:
• 2004-2020 Subaru STi

What's the difference with the HD?
The HD has the "Heavy Duty" pressure plate with a little more clamping force and slightly heavier pedal feel. The HD can handle 472 TQ vs the standard version at 332 TQ.

Features:
• Street / Race
• Driveability is similar to the stock clutch
• Pedal efforts will be slightly higher because of the higher clamp loads
• Spring center dampers to reduce drivetrain shock

Includes:
• Pressure Plate
• Clutch Disc
• Throw Out Bearing
