Tein are the best no questions asked...your looking at around 1600 to 1800 for that...if you did some modifications to the hood you could also run there Electronic Dampening Unit too around 300 for that
JIC makes some excellent Coilovers I forget what there charging
There could be a good chance Project Mu is doing coilovers for the 2g Eclipse....and I heard some really good stuff about them...but you would probably have to fork over some serious cash for those
There is probably others but if you want REAL coilovers I only suggest the top notch stuff...not the half ass crap people use...invest in the best
