Turbo EXEDY Stage 4 Twin Disc Ceramic Clutch Kit for 1986-1991 FC Mazda RX-7.
Exedy Stage 4 Twin Disc Clutch Kit characteristics gathered from HR's personal 'Real-World' testing:
- Use For: Street, Drag Race, Time Attack, Circuit Track, Autocross & Drift.
- Pressure Plate (clutch cover): Billet Aluminum, Increased clamp load over stock. Very Firm feeling but not overly heavy. Will not prematurely wear out clutch hydraulics. A nice positive feel with great feedback.
- Discs: (x2) Full Face Ceramic w/ sprung hubs.
- Engagement: Very Smooth, no chatter, transitions with broad "shippable" friction zone, no grind noise or bucking. Superior alternative to 6 & 4 single puck disc kits.
- This clutch kit is a legend. It is an outright amazing clutch that delivers in all aspects. Engages very smoothly making it perfect for daily street use while holding gobs of power for outright racing. It truly is the very best of both worlds. Perfect for high performance turbo rotary 13B 2 rotor & 20B 3 rotor applications producing up to about 640 WHP or roughly 510 FT/LBS of wheel torque. This is hands down a 5 star clutch.
