My car just got fitted with new springs and here is all the info for you guys and gals.
The GF210 coil spring is geared towards maximum performance, without compromising daily driveability. A subtle drop provides an aggressive stance, while the higher spring rates (+20% - 30% over stock) provide excellent handling and vehicle stability characteristics. These springs provide a very noticeable gain in performance when installed.
The GF210 is well mated with a performance shock upgrade to extract the full potential of the coil spring, but will also work with factory equipment.
Each coil spring application is tested for fitment and optimal weight distribution for sportier handling
17mm lower in the front
16mm lower in the rear
Spring rate
10 kg/mm front
7 kg/mm rearSo far so good. I set my setting in comfort mode on the way back home and it was fine. I can feel the difference in the ride and it's more rigid. When track day comes I should know more on how they feel. I would love to try it out this weekend, but the snow is calling me this weekend.
