I do not recomend any lowering springs out there for our cars. All of them are to low and not stiff enough. Once you understand how the spring makers come up with the spring rates, you will understand why. Your rsx has about 5 inches of suspension travel in the front and about 1/2 if a inch of that is bumpstop. When you lower the car by 1.5 inchs, you have reduced upward suspension travel by about 25%. So It would make sence that the spring rates should increase by 25%....but they can't do that cuz that much of a increase would blow the stock dampers in a couple weeks and that would result with all the little superstreet want-a-bees bitching on the interwebs on how those spring blew their shocks.... This is all fine and good.....but....the first rule in suspension tuning is tire grip sets the spring rates, spring rates set the shock damper settings and sways are used for fine tuning the handling.

Look closely.....also look at the springs that have a "-" in their range, those are progressive rates and progessave springs are dumb on Mcstrut cars....the only ones that are close to where they are supose to be are the H&R's.....but they are a 2 inch drop and those spring rates kill the stock dampers quick......a 2 inch drop also means you should up the spring rates by 40-50% to keep the car off the bumps stops ( not taking into account changes in suspension angles that result in the need to up the spring rates even more as your rollcenter goes subsurface)

The only "linear" springs I've seen for the EP3/DC5 chassis are made by Spoon and they provide a 2"+ drop.

But IMO if you're bothering to install lowering springs on stock struts, that's your own dumbass fault for doing a half-assed job to begin with. Don't bash manufacturers when it's user error.
