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.

koni yellow ang gc are a good setup but if you do a little research you will find that, thats what most people use,

yeah. looking around i've noticed that alot of people go with the koni/gc. a buddy of mine has that setup. but he has a higher spring rate in the rear. like a 450 in the rear and 350 or 375 in front. and that damn thing handles amazingly. but i've noticed that most people put a higher rate in the front. whats the reasoning for the higher rate in the front or rear?

the setup on my hatch is koni/ground controls. Much stiffer in the back though. IIRC, it's 600/800. Mostly DD, although it has been tracked a few times. Not bad on the street in all honesty.

people typically do the higher rate in the front cause there is more weight, especially if you have a b-series. also watch out for getting to stiff in the rear because its libel to slide out more, kinda sketchy if you ask me since your going fwd

never had a problem with it, it feels right no me. Helps the rear rotate a little more but has never kicked out.

yeah. my buddy that i mentioned said that is what his does. in a turn if he eases out on the throttle it will kinda slide a lil helping him around the turn and it straightens out as he gets back into the throttle.

To avoid bottoming out if you're ~2.5" lowered in the front you need ~400+ rates. For the rear 350+ starts to make good turn in.

Rear spring rate often plays a larger role in ride comfort, so people tend to get a big rear swaybar and keep the rear rates modest. I have 350/350 on progress and it's very tolerable for daily driving. I'm a tad low for 250lb front rates, but progress only had the 250, 350, and 500lb springs available.

I never have any rubbing except on large dips in the road. Here's me in the car at SoloAtlanta's novice school from April
