Lightweight flywheel for TVR Speed 6 engine. This flywheel has been designed by us to be a direct replacement for the standard flywheel and taking the standard AP clutch but offering significant performance advantages due to the decreased weight. This flywheel is fully machined from solid and with integral ring gear and triggering ring for crankshaft sensor. This flywheel weighs approximately 4 kg which is some 2 kg lighter than the original. Lightening the flywheel allows the engine to pick up faster when accelerating and this is very noticeable after this upgrade.
