Starting at number one are the SVE Lowering Springs! One of the first things you may notice from the factory is that your S550 sits a tad higher in the front than the rear. The easiest way to solve this problem is to go with a set of our SVE progressive springs! Not only will you reduce the center of gravity and body roll of your car, but you’ll enjoy daily driving. When you do lower your S550, it’ll reduce the squat during acceleration and excessive nose-dive during hard braking. This is the perfect suspension kit when driving on the street or the track. These springs will close that wheel gap while also providing a level stance for your Mustang. The progressive rate in these springs will provide an excellent ride quality similar to OEM quality.
