The ACT organic street clutch kit requires noticeable more pedal force. It will engage closer to the floor (50% down) and have a less distinct feeling than the stock clutch. This is somewhat annoying to begin with but I soon got used to it and the function is quite OK. There is also a light clutch chatter when making soft launches.
So,it is not a comfort clutch but it gets the work done and I'm perfectly happy with it since it has never slipped. The stock clutch was a PITA when moving to an aggressive and good running V4 map @18+ PSI. I've seen 20+ PSI with the ACT many times without problem and is on 19.5 every day without slippage.
The clutch delay valve was re-installed with the ACT clutch. This contributes to the vague feeling and it will be removed again.
