The last remaining components for the first chassis were the arrangements for attaching the mini rear suspension units. It was known that the hot mini racers were already using modified outer pinion mounting brackets to enable changes to rear wheel camber and toe in/out, to promote less understeer when cornering under power So it was decided to design suspension housings with potentially maximum geometry variability. The basic objective was to start with 4 1/2 inches ground clearance rear suspension arms horizontal, with two occupants and ¾ tank full. The inner mounting plates were welded to the chassis in a 1/8th.. and ¼ plate strutted housing reinforced with square tube, the outer location being in 1/8th plate secure to the ¼ inch outer plate by set screws tapped into it so as to initially produce both zero toe-in and zero camber.
