Special Note: RACING ONLY PRODUCT. If you have a Dinan Coil-Over kit and ever thought that your suspension could be stiffer for increased road feel and performance than this is the solution for you. This?pair of front springs are 19% stiffer than the ones included in the base Dinan Coil-Over package and the spring rates are optimized for track use with R-compound tires. The end result is?a suspension system that hugs the road letting you feel the course in front of you with significantly less squat under acceleration and?dive under braking.
