The R8’s chassis was stiffened with improvements to the front crossbar and rear engine support, and reinforced front suspension wishbones. Most notably, shorter springs and twin shocks at the rear dramatically improved handling. A more direct steering rack, with 3.25 turns between stops, was another major improvement. The 1966 model was tweaked even further, with stronger wheel arches and other chassis strengthening, while the door and rear numbers were lightened.
