NISMO SPORTS CLUTCH DISC FOR SKYLINE ER34 RB25DET 30100-RS252

 

NISMO SPORTS CLUTCH DISC FOR SKYLINE ER34 RB25DET 30100-RS252

**Clutch disc Outer diameter: φ250

**Spline details: φ25×24T

**Friction material and type: Copper mix

Use Clutch Disk: 30100-RS252 as a set with Clutch Cover: 30210-RS255

1. Sports clutch disc and lightweight flywheel are designed and manufactured for the purpose of improving clutch response and corresponding output improvement.

2. The resonance sound "Rattling sound" generated from the transmission and the bearing compared with the genuine Nissan product is easy produced but without any quality issue. 

3. The clutch cover and the clutch disc can not demonstrate their original performance unless they are properly combined. Make sure to use clutch disc and clutch cover made by NISMO as a set.

4. It is not necessary to process the flywheel or the transmission.

5. Please make sure that the transmission and flywheel etc. of the vehicle to be installed are not processed or modified. (It may not be suitable for vehicles that have been processed or changed.)

6. Bearings and sleeves etc. can be used as they are, except when there is a note, but we recommend that you replace them with new ones.

7. When exchanging the clutch release fork release pivot Operating cylinder Pilot bush etc etc.

8. Please be sure to check for wear and breakage etc. Also in the case of a car with a large mileage, please change in advance.

9. Clutch disc clutch cover If the friction surface of the flywheel is scratched, worn out, thermal deformation or the like, replace it with a new one.

10. The enhanced clutch increases the clutch pedal effort compared to standard products and requires accustoming to clutch meet.

11. For Ceramic Metal type clutch discs, metallic sounds and judder beat sounds may appear.

12. The reinforced clutch has an increased crimping force and pedal effort on the cover, so the clutch pedal bracket release fork etc. may bend depending on how it is used, or the life of the operating cylinder may be shortened.

13. Because the torque transmission capacity of the reinforced clutch is up, the transmission and the differential may be damaged or the life may be shortened depending on usage.

14. After installation, be sure to check and adjust the treading margin of the clutch pedal and the break connection according to the maintenance instructions.

NISMO SUPER COPPERMIX TWIN CLUTCH FOR SKYLINE R32 R33 RB20DET RB25DET 3002A-RS594

 

NISMO SUPER COPPERMIX TWIN CLUTCH FOR SKYLINE R32 R33 RB20DET RB25DET 3002A-RS594

1. This is a super-strong clutch that combines; an ease of operation with an output ceiling of more than 600ps. The development concept by NISMO that launched the SUPER COPPERMIX TWIN.

2. NISMO first floated this concept as a carbon twin product. Two years into its development, it was decided that the low μ of carbon facings could not match the performance that COPPERMIX promised. 

3. NISMO spent 1.5 years developing twin discs using COPPERMIX. This makes the SUPER COPPERMIX TWIN in total of another 3.5 years of testing and development. 

4. This is an ultimate model in the NISMO multi-plate clutch series.

Features:

5. Allowable dynamic friction torque measured at 84 kgf・m (static friction: 143 kgf・m). 

6. Can handle an estimated power of 670 ps.

7. Using a center hub increases the engagement surface between the clutch disc and the serrated section of the transmission's input shaft. 

8. This lowers the overall pressure on individual splines. 

9. It reduces wear to the input shaft and prevents disengagement problems. 

10. Having a center hub also makes installation easier than for single clutches by eliminating the risk of damaging the splines or misaligning the 2 discs during clutch assembly.

11. The ideal weight for maximum torque was obtained by using a lightweight flywheel manufactured from specially crafted chromemolybdenum high carbon steel.

12. The flywheel is provided with a special aluminum cover with exceptional heat-radiating properties.

13. The center plate is equipped with a strap function*1 that also prevents any problems with disengagement. 

14. This mechanism leverages the reaction force accumulated by the strap plate to cause the pressure plate to constantly move away from the disc. 

15. It is employed as a standard part in manual transmissions and is installed in all production vehicles.
