COOPER FORMULA JUNIORS
Overview

Coopers became Formula One Constructor World Champions in 1959 & 1960 not very long after becoming the world’s largest racing car manufacturer.
From their beginnings with the 500cc Formula 3 cars in 1946 they carried the theme through and were responsible for the subsequent rear engine revolution in racing car design. Their chassis design was often described as a collection of suspension brackets kept apart by a few tubes. Cutting edge engineering it might not have been, but good solid practicality it most certainly was.
Their ethos was one of progressive design and this enabled them to rework components previously tried and trusted in other models in other formulae.
Some, later, very influential people in motor sport had their beginnings with an involvement with Coopers. Bernie Ecclestone and Frank Williams raced, whilst Ron Dennis was a works team mechanic.

The Formula Junior cars spanned the years 1960 to 1963 with four models,
In all cases the chassis were round steel tube space frame with independent suspension all round and with rack & pinion steering.
All the models were rear engine design and the first model had aluminium bodywork whilst in the subsequent years fibreglass was used.
The cars constructed by the factory required chassis plates only if exported, whereas home market sales required no formal identification.
