What's your budget?
<$600 Progress CS-II
<$800 Koni/Ground Control
<$1000 Koni race/Ground Control
<$1100 PIC
<$1200 AMR
I have progress and 350/350 is their street/daily setup. It's tolerable for daily driving and stiff enough to promote turn in for autocross. Handled great at SoloAtlantas Novice school :P
I would honest go with koni/Ground control and go with 500F/400R and get a front/rear swaybar to compliment those. I'm running a 22mm rear progress bar with a Function7 subframe brace and no front swaybar. I really need to get a 15-19mm front swaybar. The EM1 swaybar that everyone wants is too big at 26mm. Ex/Lx civics came with a ~16mm front swaybar.
