Nick that seem very hard. 400/600 that is. Im running 450/550 which is a stiff street/track setup for the M3s. Some of the hardcore track guys run 550/650 and up. But thats to stiff for the street most of the time. Thats just to give u a slight idea... Ur setup seems really stiff, but ask some of the honda guys what they think (the real honda guys, not the retards suporting 70$ slip ons like they are actually a good product).
