Holden Commodore SS Group A
The Commodore SS 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 racing, where a minimum 5,000 base model cars were to be built, with a further 500 "Evolution" specials built to a certain specification prior to the 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.
Unique amongst all products produced by both the Holden Dealer Team and Holden Special Vehicles, these cars were referred to as Holdens, rather than as HDTs or HSVs.
