The quest for the "ultimate" in replacement clutches has brought UUC to abandoning all commonly-available aftermarket brands, and instead focussing 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. Stage1 Performance Organic is ideal for street use and track use. This clutch's engagement characteristics and pedal effort are the same as a BMW OEM clutch, very smooth and easy to modulate.
Note: this clutch contains a sprung-hub center, making it an ideal match for aftermarket flywheels to reduce gearbox rattle.
Big news for 6-speed owners!
Many 6-speed owners 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 in currrent BMWs 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.
The UUC clutch eliminates the SAC mechanism and restores traditional clutch feel with predictable and crisp engagement.
Performance Organic: is ideal for street use and track use. The enhanced 2400psi pressure plate and uprated clutch disk friction material make it ideal for daily-driven cars with power enhancements beyond 50% more than original power level. This clutch's engagement characteristics and pedal effort are virtually the same as a BMW OEM clutch, very smooth and easy to modulate.
Segmented Kevlar: is ideal for street use and track use. The enhanced 2400psi pressure plate and uprated clutch disk friction material make it ideal for daily-driven cars with power enhancements beyond 100% more than original power level. This clutch's engagement characteristics and pedal effort are virtually the same as a BMW OEM clutch, very smooth and easy to modulate. Highly recommended for street-driven turbo applications and cars fitted with SMG transmission.
Multi-Puck Ceramic: is optimized for frequent or dedicated drag-racing, high-powered modified cars, and can still be used for regular street driving. Note that slow clutch egagement-style street driving may result in "abrupt" engagement and minor chatter in the lower gears. The enhanced 2400psi pressure plate and ceramic/metallic disk lining is capable of handling power loads approximately double what the car originally produced.
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.
