tried this in the drivetrain...not getting much response...need to order soon

they offer Kevlar, Carbon Fiber or Ceramic

what are the advantages of each? dissadvantages?

i know some tend to chatter more, some hold better...etc..

planning on a Spec 4 and a lightwieght flywheel, need it to hold about 425hp to the wheels N/A...so maybe 500 at the crank.

don't wanna mess with the spec 3 due to all the spring problems i hear about.
