i've got the gr-2s with the eibach pro-kit.it has a firm ride the way i like it.tire size plays a big difference in ride quality also.my car rode better when i had 245/45/17 all the aound compared to my current setup of 255/40 and 275/40 combo.the shocks are good buy for the money but there are better ones,it just depends on what you want from your ride.
