1957 The Automobile Manufacturers Association (AMA) banned manufacturers from using race wins in their advertising and giving direct support to race teams,[15] as they felt it led to reckless street racing. This forced manufacturers to become creative in producing race parts to help racers win. Race teams were often caught trying to use factory produced racing parts that were not really available to the public, though many parts passed muster by being labeled as heavy-duty "police" parts. Car manufacturers wanted to appear compliant with the ban, but they also wanted to win.[1]
1952 Jaguar C-Type introduces for the first time disk brakes front and rear.
