So I'm sick of these Eibach springs that came on my car when I bought it used. The car is just a bit to low in my opinion, and my buddy who has stock springs seems to handle better.

Im thinking of buying some stock springs or trying to find some stiff springs that are close to stock ride height. Any suggestions?

Are the GSR and MR springs the same?

depends, go with swift springs - gray ones.

 

How low are the Swifts? Im tired of scrapping on the rough roads around here.

I think the Eibachs are 2 inches lower then stock?

So is it the higher the lbs the stiffer the spring?

 

Yup, higher lbs/in means stiffer rate. You'll also sometimes see spring rates listed in kg/mm.

Our GTWORX springs lower the car 20mm front and 15mm rear. That's about .75 inches up front and about .5 inches rear. As far as I know, every other spring out there lowers more.

We chose less of a drop to maintain as much suspension travel as possible. The bigger drop springs mean you are on the bumpstops the majority of the time. Bad for ride quality and bad for handling. The smaller drop also means we maintain better suspension geometry through a turn.

Swift springs are popular and also pretty good. They still drop a bit more than ours at 1.4 inches up front. I would definitely not go any lower.

A 2 inch drop means you are on the bumpstops before you even hit a bump, and the Swifts put you very close to them.

Wow thanks Andrew!

I dont see you guys on the spring rate chart. What are your spring rates?

 

290 lbs/in front
330 lbs/in rear

20mm drop front
15mm drop rear


That's a little firmer than a lot of springs, but you still get good ride quality since you have a lot of travel.

 

Swift or GTWorx depending on the drop you want. Assuming you have the Eibach Prokits, they drop 1.3" all around.

The stock GSR and MR springs are the same, but Swift make specific springs for each.

 

MR or GSR it won't make a difference.... but if you want better performance with compliant ride while not slamming the car you should look into robispec springs. I loved them for the road and the track.

You said your buddy has stock springs and it handles better. This is certainly plausable. Are they sportlines or pro-kit Eibachs? How many miles are on the car? I would think you would want to make sure one or more of the struts are not blown before you spend money on new springs. A stiffer spring will make the ride worse if you have a blown strut/shock.

 

What are the spring rates on the robi springs?

Very good point on the blown struts. I don't think Eibach made a Sportline for the Evo but the Pro Kit lowers it 1" or 25mm. That is only 5mm lower than the GTWorx springs. If it's clearance you're after, you may be better off with the stock springs. Or buy a truck.

 

Eibach's advertised drops are notoriously inaccurate in the real world.
