Following the success of ThundersportGB’s support races at the British Grand Prix, promotors FG Sport have asked the series to provide support races for Donington’s World Superbike round on September 7.
Series boss Dave Stewart said: "There will be one 30 minute qualifying session on Friday, one 10 lap race on Saturday and one 10 lap race on Sunday. These will be championship rounds for Thundersport GP1 and Thundersport Sound of Thunder. The regular Thundersport 600 competitors are invited to take part as a non-championship event to showcase their talents."
