In a clean sweep for TF Sport, Graham Davidson and Jonny Adam came in 5th on the day, doing enough to be crowned the 2019 British GT3 champions in the #47 Aston Martin V8 Vantage GT4. At the last meeting they won at Brands Hatch so were given a 20 point penalty.
This is one of the Championship rules that ensures close racing. There are mandatory pit stops during the race for driver changes and these previous "success" penalties are implemented next time out, keeping the race interesting for the spectator, if a little frustrating for the crews.
