Bilstein racing shocks and struts are specifically set to meet the rigourous demands of driving competition. Their success should be measured by the unprecedented levels of acceptance and use by professional drivers in virtually all major motorsports. Rallye and race units may include such features as spherical bearings, adjustable spring-seats longer or shorter than standard dimensions.
