Series Manager: Russell.
This series will be raced in the third quarter of 2017 (Q3).

The years of 1976-82 were host to the 4th Generation Group 5 Series. The period rules dictated that the lines of a production car needed to be maintained above the wheel arches, mostly everything else was unrestricted. These turbocharged Monsters with 500+ HP under the hood and no traction control or fancy driving aids demanded every last bit of skill of those who dared tame them.
