Thundersports was essentially a sports-car version of Formula Libre with cars from Sports 2000, Group 5, Group 6, Can-Am, Group C and various other prototype categories all eligible; a number of hybrid cars appeared in the series.
Thundersports was made up of a category called Future Racers, championed by Peter Brock and Ross Palmer of PROCAR fame it had never taken off and CAMS had refused to sanction the category as it was broadly very similar to the Aussie Racing Cars class.
Peer Racing entered David Kennedy and Martin Birrane in the new Thundersports series, but the pair crashed out of the season opener, held at Brands Hatch.
