With the Eibach Pro-Spacer installed, the car looks wider and better, as the wheel fills the arch. That's how the cars look gets its final touch. By increasing the track width, not only the appearance is improved, but you also achieve an optimized driving behavior combined with higher stability, as the roll of the chassis is influenced in a positive manner. Optimize the "sportive touch" to the last detail: wheels, tires, Eibach Suspension Components and Pro-Spacer! You'll achieve optimum looks and enhanced handling by moving your wheels flush with the outer edges of the wheel wells. Simply measure the wheel-well/tire gap, as shown here, and order the corresponding Pro-Spacers to put your wheels and tires out where they belong. Note: Wheel spacers require longer bolts or wheel studs for safety purposes. Always have a local shop inspect your wheel spacers to ensure you are using them properly.
