Eibach's SPORTLINE KIT is the extreme-performance spring set created for the extreme enthusiast who craves a race-car attitude for maximum street performance, with the lowest possible drop,matched with the exceptional ride quality you expect from Eibach. Engineered with the same care as their PRO-KIT springs, Eibach SPORTLINE springs achieve legendary handling by aggressively lowering your car's center of gravity, using our precision-engineered progressive spring rates. By radically lowering your car's center of gravity, the SPORTLINE springs dramatically reduce squat during acceleration, body roll in corners and nose-dive under braking. By using Eibach's proprietary, progressive spring design, the SPORTLINE springs provide the ultimate balance between high performance, extreme lowering and comfortable ride quality. When combined with today's wild bigger wheels and tires, the result is a car that handles just as satisfactorily as it looks. *Lowering amount varies by application use our application lookup for specific information on lowering for your car, truck or SUV.
