Product Details

The SPEC Stage 4 clutch is designed for race and track use where light weight and a grippy clutch material are paramount to quiet and smooth operation on the street. The Stage 4 is popular in the SpecE30 racing series and for other track cars. It uses a rigid center hub with 6 clutch pucks and no springs instead of a full clutch disc. This makes the whole assembly lighter and simpler (less likely for a failure). The friction material is rated at 425 ft-lbs, more than enough for a naturally-aspirated E30. A heavy-duty pressure plate and throw-out bearing complete the package. If clutch or flywheel woes are keeping you from getting the most from your E30 this is the clutch you should be using.

The stock clutch in the M20 E30 is not terrible but can become quickly overheated and lead to glazing on the flywheel surface and inconsistent engagement. A more robust material is needed to handle the extreme temperatures found at the track. The SPEC Stage 4 clutch consists of a carbon/semi-metallic friction material paired with a heavy-duty pressure plate. The clutch is stronger and grabs harder than the factory clutch. It has a much more robust feel and engagement. And with this specification the clutch will never be a weak point. The clutch is rebuildable to help minimize consumable costs. The SPEC clutch is designed to work with the stock dual mass flywheel or the SPEC single-mass aluminum flywheel. If this is for racing, check your rules to confirm which flywheel can be used.

SPEC Clutch is one of the premier clutch and flywheel suppliers to the tuner market. They are often found on the most highly tuned import and domestic vehicles. They are recent players in the German car community with a special focus on the newer turbo BMW models with high torque output. SPEC has been proven time after time to provide superior performance, drivability, and longevity to the most hardcare enthusiasts around the globe.
