Laser Tools Racing’s Ash Sutton doubled up with his second British Touring Car Championship victory of the day at Knockhill, again fending off standings leader Colin Turkington to take the win.
The 2017 champion led the field away from pole position, with Turkington enjoying a good launch as race one podium finisher Jake Hill was forced to defend from Rory Butcher, allowing Tom Ingram’s Toyota to swoop around the outside at Duffus Dip on lap one.
With the weight in the leading duo of cars switched for the second contest, Turkington immediately pressurised Sutton on the opening lap before a safety car was called to retrieve Josh Cook’s car from the gravel trap at McIntyre.
Having sustained heavy damage in the opening race, BTC Racing managed to get Cook’s Honda Civic Type R onto the grid for race two but his race was cut short after suffering contact after going three wide with Jack Butel and Mike Bushell.
When the race restarted Turkington was again on the offensive, with the pair’s battle bringing Ingram and then Dan Cammish into the lead battle as Hill fell back, struggling with 48 kg of success ballast in his FK2 Honda Civic Type R.
That lead battle continued until lap 13 when Andy Neate’s Motorbase Ford ended up in the gravel trap in the same position as Cook’s Honda had been, necessitating another safety car period.
When the race went green again the leading pair pulled away from Ingram, who was forced to defend until the end of the race under intense pressure from Dan Cammish, while Sutton placed his Infiniti well to hold off Turkington to the flag.
In doing so, he brought down the standings deficit to Turkington further to just eight points, again securing the bonus point for fastest lap.
His team-mate Aiden Moffat secured his best result of the season on home soil by completing the top five, finishing ahead on the road of Matt Neal who would suffer a ten second time penalty for a start infringement and eventually drop to 15th.
That promoted Team BMW’s Tom Oliphant to sixth position ahead of BTC Racing’s Tom Chilton, while Jake Hill managed to hold on to eighth position after falling back early on.
Excelr8 Motorsport’s Chris Smiley was ninth ahead of Rory Butcher, who dropped positions early in the race after going wide at McIntyre after an unsuccessful attempt at a move on Jake Hill’s Honda.
Senna Proctor – who has been drawn onto reverse grid pole race three – placed 11th in the second contest ahead of Carl Boardley, who enjoyed a strong showing in his BMW 1 Series in 12th.
Ollie Jackson was 13th in the second of the Motorbase Ford Focus ST’s while Oulton Park race three winner Adam Morgan could only manage 14th ahead of Neal in 15th after the latter’s time penalty.
The final British Touring Car Championship race at Knockhill is scheduled to get underway at 16:55 BST.
