The British Touring Car Championship's supporting series always provide plenty of intrigue and another exciting and unpredictable year is seemingly in store.
Among the headlines is a quality line-up in the Porsche Carrera Cup GB, where a trio of BTCC race winners have returned to for 2024, while the ever-exciting Deagen Fairclough is among the favourites for British Formula 4 glory, and Dan Zelos will be seeking an unprecedented third Mini Challenge JCW title.
A raft of club categories will also be making guest appearances again this year - with the Legends Cars Elite Cup and Radical Cup UK on duty at Donington Park this weekend - while a heavily upgraded Cayman will feature in the fourth of the regular supports, the Porsche Sprint Challenge GB, when it roars into action at Snetterton next month.
