This Spec clutch is designed to be used with their billet single-mass aluminium flywheel. This reduces the rotational mass and offers higher RPM capability and greater clamp load levels. The Spec clutches still offer great drivability and an almost OEM pedal feel. (weight/difficulty to deperess the clutch pedal)
Fitting a single mass flywheel will increase audible ‘chatter’ of the clutch at idle.
Your end goal & power figure should be factored in when choosing which stage clutch kit to go with.
- The stage 2+ is rated for 738 Nm on the flywheel.
- The stage 3+ is rated for 909 Nm on the flywheel.
- The stage 5 is rated for 1111 Nm on the flywheel.
