SPEC Stage 2+ Clutch

[CamWeiss]

With the new SPEC now in my car, I thought I'd give an initial review and update the thread periodically.


First a little about the clutch...
400 ft/lb capacity, sprung segmented disc, metallic on one side and kevlar on the other.
Where the fingers meet the clutch body appears to be a bit better built than the ACT I just broke.

Was about $50 cheaper than a new ACT 2100 w/ full disc.


This clutch was installed in combination with a Fidanza aluminum flywheel.

150km
Smooth, not a hint of chatter. The engagement is still a bit abrupt, but that may partially be me learning the new flywheel as well.
Pedal feel is good. Very light! Probably similar to stock.

The manufacturer specifies a 1000km break-in, so I've gotta drive like a white man for a little while.


400km
All is well. Ring and pinion in the trans are noisy.

1000km

Break-in complete.
Went autocrossing, did seven easy launches (3000-4000 rpm). Still smooth. Engagement felt fairly abrupt, but having never launched it wasn't quite sure what to expect. Will learn it eventually.

Transmission (ring & pinion) are still noisy on deceleration.

noisy and abrupt is correct
