I was going to go with Illumina's and eibachs to replace my stock suspension. I cant find any eibachs for sale, so I'm considering the Tanabe springs. They offer two different sets. One that is just a little stiffer, and lowers the car less than an inch. A second set is 20-30% stiffer and lowers the car just over an inch.

I dont drive my car much. I autocross it a couple of times a year with non-r tires. The main reason for changing is that the car feels "floaty" to me at higher speeds, and I dont like how much the front end lifts when I accelerate. I dont want to drop the car too much, and I dont want it real stiff. MY car is a 94 FD with a little over 300 rwhp, and stock suspension.

Any thoughts on the tanabe springs, or a suitable substitute?

Might look into H&Rs also. I ran them for years and liked them. Now running Tein H-Techs on Konis set at the middle perch. Got them from autoRND.

 

I have riding on Tanabe GF210's for the last year, or so. I like the progressive feeling when taking winding freeway on and off ramps, as well as tight turns on canyon roads. Eibach Sportlines are good springs too, but will lower your FD more then what you want.
