 Early models had them on all wheels, but Bristol thought the car was over-braked and they were thus restricted to the front wheels on later 403s.The 403 was the last Bristol to feature a BMW-style radiator grille.It is also noteworthy for having two extra headlamps at the side, almost pre-dating the adoption of the four-headlamp layout in larger cars (Bristol themselves adopted it with the 411 in the late 1960s).
