The pivot points of the split Ford E93A front axle. A Morris Minor steering rack was used. This style of IFS was developed in the UK by Leslie Ballamy circa 1933. He sold conversion kits for small Fords for use in the parent cars as well as in "Specials". Other marques with beam axle front ends, such as Bugatti came in for the Ballamy treatment. The Hot Rod movement in the USA also modified beam axles in the same way but may not have been as clever as the Brits to ensure that the beams were located to give a low roll centre.
Allards also used the same concept as did Austins on the Ulster Seven.. Colin Chapman was a graduate of the "1172 Formula" where Ford E93A (Anglia, Popular and Prefect) components formed the basis of cars for the class of British Club Racers. While the layout tends to endow cars with a fairly strong understeer characteristic the layout was very simple to construct and to incorporate into a chassis design. Far simpler than wishbones and coil over shock absorber layouts for instance.. at least until lightweight production cars became available with these items. The Fiat 500 Topolino, with this layout front and rear was a terrific source of suitable parts and early Cooper Formula 3 cars featured Fiat 500 suspension, suitably modified for the featherweight F3 cars. Stirling Moss and Bernie Ecclestone cut their respective motor racing teeth on these cars..
