Stage 1 – Ultra light Flywheel and Clutch

The Premier Power Ultra Lightweight Flywheel & Clutch is an entry level upgrade that gives a very noticeable driveability improvement.  It will give the driver a slightly heavier clutch pedal but the throttle response increase and improvement in engine braking is very noticeable.  For those interested in improving the performance of their Sigma but that don’t initially want the expense of an engine upgrade, this is the perfect product for you.  It makes driving the car a completely different driving experience.  With the engine being far more responsive, it’s a lot easier to flick the car through the gears, making the car feel like a sports car.  The sprung loaded centre plate also helps to protect the gearbox.  This kit is not to be confused with Caterhams lightweight flywheel, this assembly is 3kgs lighter than Caterhams own version.

This product can either be fitted to a standard Caterham Sigma engine or a Premier Power modified engine.  Once purchased this clutch is suitable for any of the Premier Power engine upgrades and does not require uprating for any of our upgrades.

The kit does include a new master cylinder as well as uprated flywheel bolts.  We do recommend on cars over three years old replacing the clutch slave cylinder / release bearing while the engine is removed from the car.

Price on application

“With the ultralight flywheel and uprated clutch my ex academy car is quicker to accelerate. Gear changes are quicker too. The car feels more nimble, which is incredible from a few kilograms off the flywheel. 

I dropped the car off at their premises near Leamington Spa. Stuart took some time to explain the change in components. I returned a few days later, when it was ready, and was kindly met at the train station and given a lift to the workshop. 

I’m very pleased with the work done on the car”
