These are the COBB Tuning Sport Springs. These particular springs will lower your vehicle by 1" in the front, and by 1.1" in the rear. When you lower the center of gravity in your vehicle, then you are improving the handling and the aerodynamics of your vehicle. These are a perfect and cost-effective option for those of you who don't want the inherent harshness of coilovers, but want that lowered pronounced look.
The progressive spring rates will provide the sport feel without being too harsh or bouncy. And if you enjoy the occasional weekend track day then your car will certainly benefit from the improved handling.
Included are a set of 4 springs that will come in a black powder-coated finish for extra protection against the elements. The front spring rates are 154-194 lbs and the rear rates are 171-217 lbs.
