In doing so, the specialist company effectively filled the void left by Ferrari's withdrawal from sports car racing to focus completely on Formula 1 at the end of the 1973 season.

The first of the long line of Michelotto prepared Ferraris was the Group 4 rally version of the 308 GTB. This was not created on the behest of the factory but instead was commissioned by several Italian and French privateers. Among the initial customers was French importer Charles Pozzi, who needed a replacement for his ageing Daytona Competiziones and would go on to order no fewer than four Group 4 308 GTBs from Michelotto.

As base for the new rally car served the original, fibreglass bodied version of the 308 GTB, which had already been replaced by a heavier, steel bodied version by this time. This also explains why most of the 308 GTB Group 4s have relatively early chassis numbers. The steel tubular chassis was carried over pretty much unaltered but most body-panels were replaced with identical parts in composite materials like Kevlar. The wider wheel-arches were the only clearly visible changes to the Pininfarina-penned lines.

Michelotto also considerably modified the 308 GTB's all-alloy V8. It was fitted with lighter heads and high compression pistons. This raised the power to over 300 bhp from the 255 bhp available in the road car. The engine was also equipped with a revised dry-sump system and an enlarged oil tank. Optimised for quick acceleration, the Group 4 was also equipped with a close-ratio gearbox and a limited-slip ZF differential that could be adjusted depending on the type of rally stage.
