Reigning British Touring Car Champion Gordon Shedden leaves the Oulton Park event rueing the loss of vital championship points after suffering a late race three retirement, costing him a sure podium finish.

The Honda driver looked set to make his first podium appearance of the weekend, while completing the second half of a dominant Team Dynamics 1-2 behind Matt Neal, but a penultimate lap puncture relegated Shedden down to 23rd and firmly out of the points.

Shedden still remains a fierce threat in the title race - sitting a joint third alongside West Surrey Racing's Rob Collard - but now trails Sam Tordoff by 27-points.

"Sometimes it goes with you and sometimes it doesn't. At the minute we just can't buy any luck but it will change. It was disappointing because it's a load of points thrown away but everyone has got a tale of woe," said Shedden.

"I don't know what caused the puncture. It should have been alright. Whether we've hit some debris, I don't know. Obviously we were close to Cook early on at the inside of Druids, we'll have to wait and see.

"The car was good, especially with the weight. Once we got going it was good. There's no point in the car being good if you're not going to make it to the end."

Though the Honda Civic Type-R took its third win of the season in the hands of Neal, Shedden said a mystifying lack of straight-line speed plagued the Halfords Yuasa Racing squad throughout the weekend.

"We're at the bottom of the speed traps at the minute. I think were 5mph slower than Goff was in a BMW over the finish line. It just becomes difficult. When it's as competitive as it is, if you're that far off you're nowhere," Shedden explained.

"We were fine last year. It's quite easy for everyone to say 'we need more boost' but we need to study whether its temperature related or something else. We certainly haven't been fast through any speed trap regardless of tyre or weight.

"When you look at the speed trap at the top of Clay Hill, we're still 4mph down on the fastest. At some stage you would think you'll get the right tyre, weight and exit ]from the corner] to negate that but it didn't happen."

Moving forward to Croft, though Shedden expects the BMWs to be difficult to beat at the 1 Series stronghold, the reigning champion holds the belief that the momentum will swing back in Honda's favour as the series moves into the second half of the year.

"Croft will be difficult. It's BMW territory. They won all three races last year so we need to find some more performance somehow," the Honda driver continued.

"We'll take advantage when we can but you've still got to look towards the end of the season. There will be tracks that will suit us better."
