IIRC you had the koni and H&R set up?
if you do, i say give it one more year with em. (even though i love and want the KW3s)
i'm sort of in the same boat as you. i need coilovers and a racing seat for the same reasons, bad driving habits! bracing myself against the passenger seat, adjusting myself in the seat mid Chicago box!
so what i did was went out and got a racing seat! my point of view alone will help me be faster. i feel so much more secure, i can see the tenths coming off now.
