Due to an upgrade, I have a lightweight flywheel and clutch plate for a 1.6 Sigma engine available for sale.
Both are in very good condition, having had approx 4,000 miles of mostly road use over the 2 years since the car was bought new from Caterham (in 2017).
Weighing 4.48kg, the lightweight flywheel offers a 2.72kg weight saving over the standard Sigma TA flywheel and retails new for £492.96 (including VAT) on Caterham's website. It also offers faster throttle response and a more sporty feel to the engine.
Happy to sell together or separately, depending on demand.
I am based in Kingston Upon Thames (SW London). DM me if you are interested.
