Group 3J Improved Production Cars
.
Group 3J Improved Production Cars is an Australian motor racing category for modified road cars.[1]
The category is defined by Motorsport Australia as being for race vehicles derived from registered production automobiles, with limited modifications to improve performance and reliability.[2] Cars must be mass-produced touring cars, the model of which has been:
- homologated by the FIA in Group A or
- commercially available in Australia as a new car through a manufacturer’s dealer network, with at least 200 examples having been registered for road use in Australia or
- otherwise recognised by MA for Group 3J[2]
Modifications to engines, brakes and suspension are permitted and a different engine, from the same manufacturer as the body shell, may be utilised.[1] Cars may be fitted with wheel arch flares, front air dams and rear deck spoilers.[2]
Improved Production Cars compete in one of four of engine capacity classes:
- 0 - 1600 cc
- 1600 - 2000 cc
- 2000 - 3000 cc
- 3000 - 6000 cc[3]
The Improved Production Racing Association of Australia (IPRA) is recognised by MA as the sole entity representing competitors in the category.[2] State championships are conducted in every Australian State and the Northern Territory and the Australian Improved Production Nationals are held annually on a state rotational basis.[3]
The category was formerly known as 3J Club Cars.[1] The name Group 3J Club Cars was used up to the year 2000,[4] and Group 3J Improved Production Cars from 2001.[5]
