BMW M3 1987

To homologate their car for Group A racing, BMW were required to build 5,000 road-going versions of their M3. The car appeared with a 192bhp (143kW) four-cylinder and was a success. The independent suspension layout is the same as the regular 3 Series, with MacPherson struts and a semi-trailing arm rear design, but the springs, shocks and bushes were uprated, along with the anti-roll bars, while up front the castor was increased to improve high-speed stability. The vented disc brakes were also increased in size and finally a limited slip differential was added. The engine had a forged steel crank, all-new alloy head with four valves per cylinder, and with short stroke/ large bore design, it could rev beyond 7,000 rpm. Side blister helped cover the wider wheels, but what isn't so obvious is the re-angled rear screen and fatter pillars, which gave a stiffer bodyshell.
