BROCK VK GROUP A

BROCK VK GROUP A

The Brock VK Group A was heavily modified by Holden’s official performance tuner, originally the Holden Dealer Team. The SS Group A existed primarily as a homologation special, created specifically so a racing optimised version of the Commodore could be utilised for Group A touring car motor racing. The regulations set down by the international governing body FISA for Group A motor racing specified that a minimum of 500 cars were to be built to a certain specification prior to said vehicle being allowed to compete. Group A regulations governed many touring car series at the 1980s and 1990s including series in Australia, New Zealand, Great Britain, Japan, Italy, Germany and the European Touring Car Championship as well as the one-off 1987 World Touring Car Championship as well as significant races like the Bathurst 1000, Spa 24 Hours and the RAC Tourist Trophy. The SS Group A model run ran from 1985 until 1992. The four models have since become highly collectible amongst Holden and performance enthusiasts. Between August 1984 and early 1985, the less powerful 5044 cc SS Group Three was built.

As the first model to be produced (March 1985 – February 1986) represented Holden’s increasing efforts in Group A racing. Available only in blue associated with the corporate colours of the Holden Dealer Team’s principle sponsor Mobil, which gave rise to the cars nickname, the “Blue Meanie”. Production began in early 1985, but part supply problems saw the HDT fail to build the required number of 500 and it missed the 1 August deadline for it to be eligible for racing that year. Production still continued and the VK SS Group A was available for motor racing from 1 January 1986. 502 cars were available only through Holden Dealer Team-affiliated Holden dealerships.

Visually the BROCK VK GROUP A had the addition of a rear spoiler, larger front air dam and a more aggressive front grill over the standard VK Commodore. Other changes included a double row timing chain (eliminating the car’s inherent weakness of 1985, a single row chain), as well as stronger conrods and suspension mountings.
