Westbourne Motorsport’s Dorlin went into the event ahead in the standings but came out of it in third – some 31 points behind new leader Max Coates and 25 adrift of Paul Rivett in second.
After two pole positions in the previous rounds at Oulton Park, this time he could qualify ‘only’ third and ninth fastest.
In race one he recovered from a tangle with Daniel Rowbottom and Lee Pattison to finish in sixth. However he then retired on the opening lap of race two with a puncture – caused when crowding at the opening bend forced his car to clatter over a kerb.
But said Dorlin: “I still got a P6 so some decent points and we can now use that as our dropped score whereas Max still has a 13 to drop.
“Title wise I’m still well and truly in with a shot. I’m not worried at all…”
Asked if he felt Team Pyro’s Coates or WDE Motorsport’s Rivett had suddenly found extra pace over him, he replied: “There’s nothing amiss. I just feel we were a bit unlucky in qualifying at Croft – nearly every fast lap I was on I got blocked.
“We definitely had the pace to be right up there so I don’t feel the others have found anything or we’ve lost anything.
“I expect to be back challenging for more race wins next time out.”
The Clio Cup has now entered a five-week break before its season resumes at Snetterton in Norfolk at the end of July.
