The foundation for the front suspension are custom Racecraft A-arms, a Racecraft K-member, and a Strange steering rack. Santhuff struts designed to Racecrafts specifications for the Pro 5.0 chassis are one-off pieces that lower the front with 200 lb/in coilover springs. Over the years, Wilkinson has changed the design parameters of these struts. Past examples Racecraft used were too tall and provided too much travel. The ASSC front struts are 2 inches shorter and allow only 3 inches of travel.
