The clutch is their organic sprung. 290 ft/lbs is plenty for a 1.6. Last time I couldn’t get much more than 220 ft/lbs at the wheels at 14 psi IIRC. So 290 crank is a plenty wide safety margin. Got it from Supermiata directly
The ACT streetlite flywheel was on sale for Black Friday from ACT directly. Was super cheap. 30% off I think
