The quest for the "ultimate" in replacement clutches has brought UUC to abandoning all commonly-available aftermarket brands, and instead focusing on a development relationship with the best street and race clutch manufacturer available. The result is a level of quality and performance beyond anything else available.

Note: this clutch disk contains a sprung-hub center (even for applications originally fitted with fixed-hub disks), making it an ideal match for lightweight aftermarket flywheels to reduce gearbox rattle. The advantage of the sprung-hub clutch design is improved resistance (and in many cases, complete elimination) of the residual rattling noise at idle that some lightweight flywheel-equipped cars can experience.

Features:

• 2400psi (or greater) clamping force.
• Torque capacity up to 500lb-ft (varies by application - see application guide.
• Sprung-hub center on all applications ("retrofit" for fixed-hub models improves clutch smoothness).
  
• Complete elimination of problematical SAC (Self Adjusting Clutch) mechanism for applications originally fitted with SAC.
• Performance friction material fully bonded to steel disk backing plate for improved heat dissipation and durability.
• "Massive overkill" drive straps more resistant to breaking under extreme or ultra-high revving custom motors.
• Marcel spring clutch disk "wafer" for enhanced smoothness.
• Pressure plate cover manufactured by Sachs in Germany, performance diaphragm manufactured in USA.
• Genuine Sachs release bearing and alignment tool included.
• All clutches are "direct fit" and require no modifications.  Normal installation procedures apply.
• SFI-certified manufacture.
  

Big news for owners of E46 3-series/M3, E39 5-series/M5, and Z8!

Many owners of these cars have experienced mushy clutch feel, inconsistent engagement, and premature wear of the clutch in their manual-transmission cars.  The reason is quite simple - the original BMW (LUK-manufactured) clutch has a new "SAC" (Self Adjusting Clutch) design.  This new mechanism built into the pressure plate is supposed to keep the clutch pedal engagement point the same as the clutch wears... but in all reality, it's a case of  "an answer to a question that nobody was asking." They have added a layer of complexity and feedback isolation, filling a need that didn't need filling - it is not too often that anybody notices that their clutch engagement point as moved 1/2" over 50K miles.

The SAC mechanism itself causes problems; it over- or under-adjusts the pressure plate and therefore causes the clutch to slip or burn out prematurely. They are also known to shift, causing the pressure plate release fingers to slip off the plate, keeping 1/3 of the pressure plate engaged at all times. Bottom line is that the only fix is a complete clutch job, and your dealer is likely to claim "driver abuse". We have seen it happen too many times.

The SAC mechanism may not give a clean release like a standard clutch. Instead of just two sets of springs, there is an adjuster mechanism that makes engagement feel mushy or slow.

All UUC Performance Clutches for these models use an all-new design pressure plate that does not have the SAC mechanism.  The resulting improvement in feel is immediate - the clutch is easy to modulate and is consistent, regardless of temperature.  Additionally, the reliability and lifespan of the clutch are enhanced.  The UUC clutch eliminates the SAC mechanism and restores traditional clutch feel with predictable and crisp engagement.

All clutches are "direct fit" and require no modifications.  Normal installation procedures apply.
