Young was judged to have ‘caused a collision’ as he and Coates disputed the lead – and ultimately the victory – as they braked at high speed into the Club Chicane for the final time.
Coates’ car was sent spinning into a barrier and retired with damage, while Young kept going to cross the line in first place.
Subsequently the championship’s BARC clerk of the course has disqualified Young from the result meaning Hammerton – who finished second on the road – has inherited his first win.
Second and third positions in the amended result go to Team HARD’s Jamie Bond and MRM’s Tyler Lidsey.
Young appealed against the clerk’s decision but this was upheld by the event’s stewards in a separate hearing.
His disqualification also means he loses the two bonus points he had collected for setting the race’s fastest lap – these now instead going to Coates who set the next best lap time.
Coates therefore will go to the next two rounds at Knockhill with a ten-point lead in the standings after Young had brought it down to just three when he won Saturday’s opening race at Thruxton.
Bond is now up to third, 32 points adrift of leader Coates, while Hammerton’s win – his first in the Clio Cup – moves him past Jade Edwards into sixth.
