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 Eibach Pro-Kit springs, Eibach Sportline springs achieve legendary handling by aggressively lowering the center of gravity of your car, using Eibach precision-engineered progressive spring rates. By radically lowering the center of gravity, Eibach Sportline springs dramatically reduce squat during acceleration, body roll in corners and nose-dive under braking. By using the proprietary from Eibach and progressive spring design, Eibach Sportline springs provide the ultimate balance between high performance, extreme lowering and comfortable ride quality. When combined with the wild 18 inch, 19 inch or 20 inch wheels and tires of today, the result is a car that handles just as white-hot as it looks.
