"LA CLUTCH TWIN", which is twin plate clutch with the concept of LA CLUTCH, has been released for FD3S.
Maximum torque 73kgf-m, horsepower 700ps. With big capacity as metal clutches, easy clutch operation as stock. High total balance clutch system.

 

 

1 Lightweight cover and diaphragm spring with optimized characteristic

Large capacity clutch systems usually require heavy pedal pressure. With the diaphragm spring, which has optimized characteristic, it requires only proper pedal pressure. Although it has stiff pedal feeling, it is incredibly easy and stress less operation from street to circuit during. Cover is made of forged aluminum, which is stiff and low inertia.


2 "Pivot Ring" for advanced controllability

Pivot Ring that is low stiffness spring on pressure plate increases clutch engagement zone. It eases clutch engagement operation and it is as easy as stock clutch.

 

3 8.5 inch "MG Composite Disc" with damper

In order to increase capacity, new 8.5 inch disc was developed. Damper of the disc eliminates gear noise during operation and protects transmission from shock torque. Because of the stable friction coefficient, clutch operation is easy and prevents uncomfortable vibration during clutch engagement. Independent type enables lightweight and stiff structure with smooth shift feeling and precise operation of disengagement.

4 "Lifting Plate" for fixing wear balance of disc

By repellent of lifting plate on both sides of center plate, position of center plate will be always centered during disengagement. It improves life of disc and reduces mechanical noise of multi plate clutch.


5 "Lightweight flywheel" for quick response

Weight of flywheel is properly reduced for each vehicle type for better response and smooth driving as too less weight cause driving difficulty.
Round drive boss enables optimized inertia performance.
Total weight of clutch kit is also lighter than stock.

 

 

■ Safety Precautions
  • Acceptable Range is the range of engine torque that the clutch can be used for except intentional overheating of clutch.
  • Acceptable range by condition is the range that the clutch might slide by rough operation, kick back from tire and distortion of parts etc.
  • Over the limitation is the range that the clutch might slide during clutch engagement at high rpm.
  • Mechanical limitation is the point that sliding starts when accelerated during driving.
