184mm Clutch Kit for Renault R5 GTT | single and twin-disc

RENAULT R5 GTT 184MM SINGLE AND TWIN-DISC CLUTCH KITS 

APPLICATIONS: 

This clutch kit was specifically developed for the Renault R5 GTT and includes: 

• 184mm (7.25”) Lightweight Flywheel (3.05 kg)

Clutch options:

• Single-disc clutch → Capable of handling over 400 hp and 450 Nm, depending on the configuration. Weight: 2.80 kg 

• Twin-disc clutch → Supports over 1,000 hp and 1,200 Nm of torque, depending on the configuration. Weight: 4.20 kg 

Clutch disc

• Custom Aluminum Spacer → Included in the single-disc clutch kit, this spacer sits behind the OE HRB. Combined with the Stick-up Adapter, it ensures the same working travel as the OE HRB 
  
  

Improved Pedal Feel & Modulation →  

• The spacer ensures the correct throw-out bearing travel 

• The stick-up adapter allows proper seating of the release bearing against the diaphragm fingers, improving clutch pedal feedback 

• The OE hydraulic release bearing’s flat fulcrum point often struggles to align with the flat diaphragm of racing clutch covers, leading to poor pedal feedback. Our Stick-up Adapter with a round fulcrum point significantly enhances pedal feel and modulation, which is crucial for a smooth launch on the starting line  

Note: 
 

The spacer is not required for the twin-disc version 

COMPONENT FEATURES 

Flywheel 
 
✔ Weight: Just 3.05 kg 

✔ Material: Forged CrMo steel, nitriding heat-treated
✔ Hardness: Achieves HRC 58~62, twice as hard as standard flywheels, preventing excessive wear (especially on the starter ring gear) in high-compression engines 
✔ Longevity: The higher the HRC value, the more resistant the flywheel, leading to longer service life & reliability 

Clutch Cover
 
✔ Material: Forged 6061-T6 aluminum, treated with hard anodizing for increased strength, durability, and scratch resistance 
✔ Construction: Steel-riveted legs for near-lifetime durability. Hardened steel thrust buttons/rivets offer a smooth and durable surface for the clutch cover legs, pressure, and floater plates.

The tightening torque for the cover-to-flywheel bolts (M8x1.25, grade 12.9) is 41 Nm.

 
Top/Pressure & Floating Plates 
 
✔ Material: Forged chromoly steel, cryogenically treated in some applications for superior strength and longevity 
 
Clutch Discs 
 
✔ Material: Sintered, with multiple design options 
✔ Standard version: Features three large pads 
✔ Customization: Custom splines available upon request 
 
Aluminum Spacer & Stick-up Adapter 
 
✔ Spacer: 6061-T6 aluminum, red hard-anodized finish 
✔ Stick-up Adapter: Hardened steel with a 50-55 HRC rating for minimal wear and long-lasting performance

KEY FEATURES & BENEFITS 

✔ Single disc supports over 400 hp and 450 Nm and over 1,000 hp and 1,200 Nm of torque for the Twin disc version (depending on clutch disc & diaphragm specs) 
✔ Huge weight reduction compared to the OEM flywheel & clutch kit, resulting in: 

✔ Enhanced gear shifting at high RPMs 
✔ Extended lifespan of friction components with low replacement cost 
✔ Full Plug & Play system → No modifications required
