Drifting in the south is dieing fast most practise day locations left are North of brum .To my knowledge your closest would be santa pod for the type of day your looking with pens to learn your craft as such.
@Docrwa might know more dunno if matchams still runs but I belive that was a banger track which you want to avoid anyway and I don't blame you
You've either got full tracks like 3 sisters Pembrey teesside or banger racing dressed up as drifting at Buxton Birmingham wheels etc
Rock outer paddock days were a great learning place as is pod with little to hit but Rockingham is now unlikely to be with us much longer and pod Is well pod
