Off the top of my head I can think of

Tein S-tech
Tein H-tech
Racing Beat
RS*R Down
RS*R Race
Eibach (Discontinued)
Ground control sleeves


I'm looking to get rid of my H-tech springs. I think they pretty much suck since they slam the car on the ground and are more for appearance then any type of actual suspension gain.

I'm interested in finding out what springs have a more aggressive spring rate then stock, but retain a near stock ride height.

My last resort is to use a ground control setup ( I have bilstein struts), however my goal with a daily driven car is to retain the factory rubber upper strut mount to maintain driveability.

Btw I think you can still find Eibach Pro-kit at some shops.

 

I've got some H&R springs I would sell cheap just to get them out of my sight.

 

I think the RSR race springs with Koni Yellows was the best setup I had before I went with a full aftermarket coilover. Im not sure if RSR still manufactures the race spring, as I remember I had to wait and search a while for a used set to pop up when I was looking. They handled my 265/35r18s up front without rubbing during hard cornering.

 

i have Tanabe GF springs, great ride, and excellent ride height

 

i just took off a set of eibach pro-kits for coilovers. if your interested, pm me.
