Abstract: A center section for a crossmember of a vehicle chassis comprises a driveshaft hoop, crossmember attachment areas extending generally from opposing sides thereof, and trailing arm mounts on either side of the driveshaft hoop for attachment of one or more trailing arms to the center section. The crossmember attachment areas have heights that allow attachment of crossmember portions to the center section at offset heights. A method of constructing a crossmember of a vehicle chassis comprises providing a center section having crossmember attachment areas of predetermined heights extending generally from opposite sides of a driveshaft hoop, and attaching crossmember portions within the crossmember attachment areas at heights that are offset from each other.

Abstract: A three-piece roof assembly is provided for racing cars in which the two side members are fixedly supported on the frame of the vehicle and the center member is positionable at a selectable canted angle relative to the side members. The center member is formed with laterally extended flanges that overlap the side members to maintain structural integrity between the center member and the respective side members. The canting of the center member creates a gap that varies in width from front to rear. The process for canting a race car roof is significantly simplified and involves fixing the side members to the frame of the vehicle, then positioning the center member at the desired angular orientation, and fixing the center member relative to the side members. The variable width gap between the center member and the side members can be filled with weld material and painted.
