Roman Bilinski was disqualified from the opening Ginetta Junior race at Donington Park.
The In2Racing driver had converted pole to a race win in challenging conditions on Saturday afternoon, but a wheel bearing failed to pass post race scrutineering.
Having challenged Bilinski for the victory right to the flag, championship leader James Hedley was promoted to the race win, with Zak O’Sullivan and Theo Edgerton completing the podium paying positions.
