For the ultimate in twin disc performance, the Clutch Masters 850 Series Race Twin Disc Clutch Kit (with Aluminum Flywheel) for the Nissan Skyline R32 R33 RB25DET (Push Style) 06045-TD8R-A stands out as an exceptional choice. Developed from pure racing technology, the FX850 system features an 8.5” (216mm) Twin Disc clutch designed to hold tremendous horsepower and torque while maintaining reasonable pedal pressure. Initially created for engines and transmissions with smaller bell-housings, the FX850 is ideal for both high-performance street applications and track use. By increasing the clamping force of the pressure plate and expanding the square inches of usable disc area, the FX850 significantly boosts clamping rates with an average of a 50% increase in pedal pressure depending on the application.

The cover assembly of the FX850 is machined from billet aluminum and then Type 3 hard anodized, giving it roughly 25% more tensile strength than competitors' cast units. By eliminating flex in the cover, which can reach up to .030” in cast or stamped units, our billet covers exhibit only .003” of flex. This rigidity ensures that all movement applied to the diaphragm of the clutch from the throwout bearing is used solely to engage and disengage the clutch, enhancing driver control and consistency. The result is greater clamping force over the same area compared to cast or stamped covers, ensuring all the engine's power is effectively utilized.

The FX850 Twin Disc can be upgraded to the DLX series. In the DLX series, both discs are inherently dampened by directly connecting a rigid disc to the disc with the sprung hub, allowing any shock load to transfer through to the dampened hub. This setup works exceptionally well for daily-driven cars with high horsepower and race cars needing extra protection from drivetrain shock.

A unique feature of Clutch Masters' FX725 and FX850 Multi-Disc Kits is the QR System (Quick Release Pressure Plate). This innovative system incorporates three spring-loaded bolts that allow the pressure plate to engage and disengage evenly and smoothly, significantly reducing internal clutch noise and chatter by up to 50%. The QR System offers quiet and smooth operation for street users while delivering the robust performance required by a race clutch.

Our aluminum flywheels are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA, and NASA. These flywheels are Type 3 hard coat anodized to ensure durability and performance longevity. Each aluminum flywheel includes a replaceable insert.
