I had AB Racing Sport Springs on my last car and loved the way the car looked and handled on the road. With my car now I decided to go all the way and get the coilover suspension. From day one when I got them installed it was night and day compared to my cars OEM Sports Suspension. The ability to go faster and harder on turns is amazing. The ride quality is not bad at all. It s not a bone jaring or kidney punching ride. Yes it is stiffer than OEM suspension but it s still a comfortable ride. The ability to dial in the ride height is great because it gives you the liberty to set the car any way you want. I took my car to Willow Springs Raceway to test my new suspension and it performed awesome. I am very impressed and very happy with this product. This coilover setup is the best for both street and track event use. AB Racing is the way to go in my humble opinion.
