FORD SIERRA 2.0 RS COSWORTH CLUBMAN

Description

This is a particularly interesting example of the legendary 1986 Ford Sierra RS Cosworth, built to Clubman Group A specification and incorporating a combination of genuine Ford Motorsport components, Group A competition equipment and selected Group N and standard production components.

Chassis, Suspension and Braking

The foundation of this Sierra is its genuine Ford Motorsport Group A bodyshell, featuring extensive seam welding to increase structural rigidity.
Its original Ford Motorsport chassis identification plate remains welded into the correct position, providing an important identifying feature of the competition bodyshell.
The front suspension and suspension control arms retain standard production specifications, while the rear suspension features coilover shock absorbers.

The rear braking system remains standard, while the front brakes have been upgraded with reinforced components, although these are not Group N specification.
The braking system incorporates Group A specification brake master cylinders, a Group A competition pedal box and an adjustable brake balance regulator.
A hydraulic handbrake is also fitted.

An aluminium sump guard provides additional protection to the underside of the engine.
Engine, Transmission and Motorsport Electronics

The Ford Cosworth 2.0 litre turbocharged engine is equipped with an original Ford Motorsport Magneti Marelli ECU.

The original air filter housing remains intact and unmodified, preserving an important element of the period engine installation.

The car also features selectable turbo boost settings. Power is transmitted through a standard five speed manual gearbox with a conventional H pattern gear selection, rather than a dogleg competition gearbox.

A limited slip differential distributes power to the rear wheels.
The electrical installation includes a works specification fuse box, another notable Ford Motorsport component.
