GP3 team boss Trevor Carlin is "gutted" by his charge Nick Yelloly's demotion to the back of the grid for race one in Valencia, and believes he would have had the pace to win from P3 on the grid.
Yelloly will start from 26th on the grid after stewards found his car's floor to be too low after qualifying.
Carlin accepted the ruling, and series officials are happy that it wasn't an intentional move to run the car too low but purely a mistake on the team's part.
"I'm gutted," said Carlin. "We tried the test maybe 20 times, but there was one part of the floor that was just too low, the gauge wouldn't go under it.
"Maybe we ran it too close, maybe there was some accident damage, we're not sure. We checked our other cars immediately and they were close but fine.
"I really think that Nick could have won from there. It was his best-ever qualifying performance in the series, and we've looked at the race pace of [main rival teams] ART and Arden and think we're in better shape.
"All we can do now is shoot for eighth place [reversed-grid pole for race two], which is a massive ask around here."
