Holden Commodore VS














A very special car and practically unbeatable when raced in the UK

Imported from Australia where it was sucessfully campaigned by the Wynn's Racing/Gibson Motorsport team driven by Darren Hossack and Darren Pate in the 1997/8 Shell Australian Touring Car Championship.


It also competed in the world famous 1000km Bathurst race - pictured left descending from Paramount Mountain (also with David Parsons and Simon Wills driving)

The car is powered by a 6.7 litre V8 730 bhp General Motors engine which is specially modified by Ric Wood. Power is transferred by a Holinger 6 gearbox to a heavy rear axle. Fuel is supplied from a 120 litre bag tank via electronic fuel injection. Ignition will also be computer mapped. All aspects of engine build, tuning, injection and ignition are set up by Ric Wood himself.

With twice the power of the average 2 litre British Touring Race Car, suspension and brakes have to be top notch. Suspension is heavily modified over the standard road car with McPherson struts and Penske dampers up front and coil-over shocks and watts linkages at the rear.

There are driver adjustable anti roll bars on front and rear. Brakes are vented discs operated by 6 piston AP racing calipers. Brake bias is also driver adjustable. The car runs on 17x11inch "Technomagnesio" cast magenesium alloy racing wheels running 280/40x17in Dunlop tyres. Race weight is set to 1300 Kg giving a power to weight ratio of 561 bhp/tonne.
