Hey all,
My 17' Si was used as a mule car for the new ACT clutch system. Here are some specs:
I cannot talk highly enough on the quality and general drive-ability of the clutch. No clutch chatter. No CEL. There isn't even a noticeable difference in operational noise that seem to plague single-mass flywheels. Revs drop more quickly now with the lightened rotating assembly. I plan on removing the clutch delay valve this weekend as well; I'll update this post once I finish. The car currently has a TSP Stage 1 tune on it. I was experiencing some slippage in 4th gear with the stock clutch. Obviously now with the ACT clutch, slippage has been eliminated. I plan on running a e85 tune in the future (Once the TSP plug-n-play kit comes back into stock).
I also had the opportunity to get a tour of their facility. They make just about everything in-house; able to maintain strict quality control on all their products. All clutch assemblies are balanced to .25 oz-in (Stock systems are usually balanced around .50 oz-in). ACT has historically striven to produce the highest quality options; never rushing to be the first manufacturer to release a product.This specific clutch has been in the works for some time now. I actually had an ACT sprung 6-puck clutch in a previous car (Mazdaspeed6)- my experience with it was great. In previous interactions, their customer service was always top-notch.
If anyone is in the market for a new clutch, I would highly recommend the ACT kit. Although it won't be released until Fall, I believe its worth the wait.
I'll keep this post updated and attempt to answer any questions.
