Every Eibach Pro Kit is designed specifically for your vehicle to ensure the lowering springs are a perfect match.  The spring rate and amount of lowering are designed to close some fender gap, but also to ensure your car is balanced and agile without sacrificing safety or ride quality.  These springs will work with the factory shocks, but could accelerate wear on old shocks. Eibach Pro Kit is designed so well, that Eibach gives your springs a one million mile warranty. Eibach Pro Kits from Redline360 include all 4 springs - front springs and rear springs.
