Flywheel is here from SPEC. 18.85 lbs.
The flywheel isn’t cheap but with the replaceable steel friction disc it should be infinitely rebuildable, never need to buy another one again.
And the clutch! This combo is SC361R-2-H. It’s a part number that doesn’t really exist on their site, Stage 1 clutch, organic full face disc, rigid hub, upgraded with higher clamp load option, brings the torque rating up to 470 ft-lbs. In other words, lots of headroom now and room to go crazy later…
Came in at even less weight than I had expected, likely in part due to the rigid hub. 12.35 lbs.
Combined weight with flywheel comes to 31.20 lbs, ~20 lbs lighter than factory clutch and flywheel combo.
There’s no pilot bearing in the Camaro setup, so a sprung hub will self-destruct in short time. Because it is a rigid hub, the friendly organic solid disc was chosen so that it’s still (hopefully) relatively easy to drive. A pucked disc with rigid hub would be a light switch, and with an est. 470 ft-lbs of capacity in the above setup, there’s no need for a more aggressive disc anyways.
