I like my CenterForce diaphragm Pressure Plate. But I pulled the CF II disc out after a short time; It was just too harsh for street duty, for me.
According to my Eighth-Mile trap speed, my engine is making 430 hp. I am currently using factory 340 discs, but they have a limited lifespan. They like to crack the spring pockets and throw springs out.
And surprise surprise, I swapped out the 340 overcenter spring for a 318 spring, and the CenterForce is happy even past 7200 rpm.
And it shifts sooooooo easy.
what's ACL
