Stage three will not be driver friendly. Will probably chatter a whole lot. Handles 360 Horse Power though. If that is not enough, you can get the Stage 3+ kit.
I am using the SPEC Stage1 and SPEC Billet Flywheel. Very smooth & reliable. Always grabs, never chatters. I am not making any significant horsepower either though.
