Group 3J Improved Production Cars is an Australian motor racing category for modified road cars.[1]

The category is defined by the Confederation of Australian Motor Sport (CAMS) 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 CAMS 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 CAMS 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]
