These are precision CNC machined in the UK from a forged billet of chromoly steel. Made to OEM dimensions retaining OEM timing markers, no modification is required to fit.
The unit comes dynamically balanced with the starter motor ring gear machined into the flywheel for improved high RPM safety. Weight is lightened at 9KG improving engine response through reduced intertia, other weights are available if preferred.The clutch is made by Sachs Race Engineering in Germany. This features a reinforced cover plate and heavy duty sprung hub with a choice of organic or cerametallic friction lining. Organic is recommended for most road use and light track work. The lining is updated with metallic particles for improved thermal holding.
The cerametallic offers a more direct engagement hence usually reserved for track or competition work where thermal input is increased for prolonged periods of time. The sprung hub is a vital part of a road going dual to single mass conversion due to acting as a vibration damper between the engine and gearbox, this is usually incorporated into the dual mass flywheel and allows for a more OEM progressive clutch engagement whilst prolonging gearbox longevity.
The heavy duty friction disc has a larger maximum capacity before hitting the stop position of the locating rivets allowing for a higher transmittable torque before longevity is reduced. The reinforced cover has a larger torque holding which improves resistance to aggressive driving and the lightened flywheel improves response. The combination gives faster, more direct gear changes without the uncomfortable sacrifices of a race clutch.
We can supply an unsprung hub for a more direct drive and higher torque holding if that is preferred. Let us know if you'd like anything other than the standard weight and a sprung organic friction disc. Some stock is carried but the flywheels are usually machined to order and can take 4-6 weeks. On the plus side, this means we can machine custom variants of these with ease, different weights including catering for a full range of competition clutches in 140mm, 184mm, 200mm and 215mm are all available for reduced inertia and improved stiffness.
