The solid rear discs (253mm dia) come from a UK Ford Sierra as do the hubs and calipers and are more than capable of stopping a lightweight car. They are bolted to the Banks fabricated uprights which I bought together with the front and rear tubular wishbones. One can upgrade to aftermarket higher spec items, but probably you'd end up with too much bias towards the rear. Used in conjunction with the AP fronts, the car slightly nose dips when the brake pedal is applied. Also shown are the US Carrera shocks and springs.
