Which springs do you guys think are softer? I already have Bilstein struts and Hotchkis 25.4mm sways and now I just want to compliment them with a MILD drop of about an inch. I was leaning towards the H&Rs because I had them on my S2000 and they weren’t bad, but im not sure if they are the way to go now. With the Bilsteins my car is already pretty firm on stock springs so I don’t want anything a lot stiffer. Thanks for the input...

OOh and if anyone has pics of either drop on a sedan with aftermarket struts please post them.

prokit and tokico hp shocks. very good ride quality. 2 finger gap all around

Id say the Eibach's are going to be the softer spring. When I had them on my coupe, I was actually shocked (no pun intended) at how smooth they were.

15 inch rims, stock tire size (fuzion hri). idk what the deal is with that, people ask me all the time if the rims are 16s and what kind of special tires. lol they are all stock fatty size lmao. nothing to see here folks. and why do people love the way this tire looks? omg, it looks like any other tire i see.

h&r sport, least drop - best rates

i believe the eibachs are softer. Why not just email both manufacturers and ask for the spring rates. It'll be more accurate then going off someone else's butt dyno.

i couldn't find one on 7th gen. found some spring rates on the 6th, but you can probably assume they'll be similar to the 7th gen.

I would email the manufacturers to get concrete numbers but they should give you an idea.

both are progressive springs, they dont have linear spring rates.

 
Rep Power: 320

just because there progressive doesn't mean they dont have spring rates. look at the list half are progressive and have spring rates.

h&r sports are like 350 spring rates, and they still ride very comfortable

96-00 EX - 165F/80R (P/P)

what does the numbers means?

Spring Rate is the amount of weight needed to compress a spring a certain . Springs are rated in LB/in (in metric system kg/mm), or specifically, how many pounds of weight are required to depress the spring by one inch.

With a linear spring, the spring becomes linearlly stiffer as you take the car to its limit.

With a progressive spring the spring becomes expondentially stiffer as you take the car closer to the limit. Benefit to a progressive spring is that you can get away with a softer spring for daily driving but still have the stiffness when at the limit.


The benefit to a more linear spring is that fact its easier to predict how the car will behave.

For example, you'll notice the integra type R has a linear front and a progressive rear stock. When you get serious with suspension you can play with the spring rates, hence why people like buying gc coilovers because you can go with custom spring rates.

hmm maybe go with H tech springs from tein? but its not gonna be very low at all, kinda a waste for less than 1 inch.

ya I want like an inch because the bilsteins made the rear of my car sit a little higher then it was stock lol.
