im planning to lowered my car all the way.. but i don't know what kind of spring or coil over im goin to buy... so please help me... [mtv pimp my ride... (joke)]
Progress Group makes coilovers which is what I have on my crx. The aren't adjustable shocks though and a little rough but also very tight and no continued bounce. If I were you I would really consider TEIN. They have complete adjustability in which you can control from inside your car, which is very convenient. Expect to pay around $1000 or more for a nice set of either of these.
if your still looking for springs or coilovers i would have to suggest either the tein s.tech springs. I put them on my girls si and there real nice. For a coilover system i would get the SKUNK2 PRO S FULL COILOVER KIT HONDA CIVIC SI FG 06-07. My friend got it and we just put it on worth the money i think
