Comment by Steve Tracy on 'Testing JWT’s Nissan 370Z Ultra Light Flywheel'

I've been really pleased with my JWT FW/Stage 2 Clutch on my V35C's VQ35DE, it really opened up the rev happy on the motor esp now with ECU changes. Mine was an older '04 and was capped at 6850 cutoff, I raised to 7400 and it's smooth to 7200 easily. It's so responsive w/o the boat anchor and minimal chatter at idle.

Curious to see that the dual mass FW for the 370 weighs in a 32 lbs, same as last gen, but the new JWT weighs in at 16, which is heavier by 3-5 lbs than the VQ35 version?

Larger surface area maybe?
