Starting the second of the weekend’s two races from pole position, Young was in front heading through the first bend, Old Hall.
However, on a tighter line than normal – because he was protecting the inside line challenging Coates to his outside – his MRM car got away from him and spun right, clattering into the barriers at significant speed.
It meant he was immediately out of the race – his first retirement of the season. He was seen hobbling away from the scene but later reported he was fine.
“We’d set the car up too loose at the rear – simple as that really,” said Young.
“I could tell on my out lap it was too loose which is why I had a quick spin then!
“When I got to the grid I told the team but there was no time to make any changes by then – I just had to go with it and obviously it caught me out.”
The 17-year-old from Belfast added: “It’s a shame as I’d been looking forward to a close race again with Max and Jamie (Bond), plus Ben (Colburn) also started to get involved.
“But at least we’ve got time to repair the car – I’ve had worse accidents. I was only limping because I’d banged my knee on the steering column. I’m fine.”
Young had in fact won Saturday’s opening race of the event to turn a 12-point advantage over Coates at the top of the table into a 20-point margin.
But his crash on Sunday means he has fallen six points behind Coates in the standings. He now has to wait until early August for the Clio Cup’s next two rounds before he can try and strike back…
Interestingly, his retirement means he and Coates both now have a zero against their names which they can use as their single dropped score for the season – in other words their points tallies will be true, doing away with having to think about discarding any worst result.
“It’s Snetterton next in just over a month where I made my debut last year so it’ll be something to look forward to,” continued Young.
“I think it’s going to get tighter between us, particularly with Jamie looking good and maybe even Ben and my team mate Brett (Lidsey) having a say in results.
“Thruxton I’ve never been to and Knockhill will be new for all of us – the gap’s only six points so it’s going to hinge on things like getting the bonus points for fastest lap and leading…”
