Optima 4 Point Clutch Complete Aluminum Black - Presentation:
- New OPTIMA CS400 4-point clutch. An innovative principle, incomparable efficiency!
- Delivered with 0.9 mm springs (original for slippery tracks), 1.0 and 1.1 mm for grippy tracks.
- Screwed pins for easy maintenance.
- 2 black aluminum weights (heavy with little contact surface) for bonding early but not completely, and 2 gold aluminum weights (light with a full contact surface) for bonding later but completely.
- No break-in necessary, because the weights are originally bell-shaped.
- Use of “Standard” dimension bells, internal ø 26.5 mm.
- Holes in the flywheel to unblock the engine during break-in without marking your CS400.
- Springs positioned inside the flyweight to prevent them from heating up and limit wear on the bell.
- On the track, the CS400 provides new sensations of ease and efficiency. Traction is increased, the car is more easily controlled even in extreme conditions, the engine exudes health, and autonomy is greater…!!
