i've had the ACT HD Pressure Plate and 6 puck sprung disc in my car with my fidanza lightweight flywheel for about 3 months now (5,000 mi). i love it; hadn't had any problems with it yet. it revs quickly and has immediate engagement (due to the 6 puck disc).

 

c.tran do you track your car???

sounds good though.

I have an 8.6 lb ACT flywheel, stock everything else. No chatter whatsoever.

 

I have a fidanza flywheel in my integra gsr turbo pushing 428hp and 280tq as a dd and now at 10,000 mile its still going strong. on my s2000 i have a exedy st.1 clutch with f1 flywheel and i love it also. no issue with this set up at all.

 

20+K miles and still good to go.

 

sounds good as!!!

cheers for the feedback!!!
