    We've installed hundreds of lowering springs on the S550 Mustang cars, and one of the most popular has always been the Eibach Sportline lowering springs! We ultimately find that the majority of the customers purchasing these are looking for a really aggressive drop on their car, while not having to spend the increased costs for something like a coilover, or airlift system. Check out the couple of photos of them installed on various S550 cars that we've done here at Parker Performance - and we can take care of getting you your Eibach Sportlines, too! *Installation available at an additional cost as well!* Details below directly from Eibach: 

    The First Step In Suspension Performance

    Eibach SPORTLINE is the extreme-performance spring set created for the extreme enthusiast—the one who craves a race-car attitude for maximum street performance—with the lowest possible drop, but with the exceptional ride quality you expect from Eibach.

    Engineered with the same care as our PRO-KIT springs, Eibach SPORTLINE springs achieve legendary handling by aggressively lowering your Mustang's center of gravity, using our precision— engineered progressive spring rates.

    By radically lowering your car's center of gravity, our SPORTLINE springs dramatically reduce squat during acceleration, body roll in corners and nosedive under braking. By using our proprietary, progressive spring design, our SPORTLINE springs provide the ultimate balance between high performance, extreme lowering and comfortable ride quality. When combined with today's wild high-performance wheels and tires, the result is a car that handles just as white-hot as it looks.
