Eibach springs have supported innumerable race and championship winners over the last two decades. In series as different as Formula 1 and NASCAR, the winning factor is often chassis setup and tuning. When everybody has comparable power, the guy who wins is the guy who can put that power to the ground-and maintain his momentum through the corners. The list of Eibach partners reads like "Who's Who" in Motor Sports: AMG, Audi, BMW, Ferrari, Ford, Honda, Lamborghini, Lola, Mazda Speed, Mitsubishi, Nissan, Subaru, Porsche, Renault F-1, Toyota, and many, many more.
