Reigning British Touring Car champion Gordon Shedden has given himself every opportunity of retaining his 2015 crown after 'digging deep' at Silverstone to slash Sam Tordoff's advantage to just a mere 11-points.

Honda's race day started off in the worst way possible after both Shedden and Matt Neal suffered what could have been title ending punctures during the opening race.

However, Shedden clawed his way back from 23rd to eighth in race two, which later meant the Scotsman would start the final reverse grid race on pole position after his finishing position was picked out in the grid draw.

Shedden didn't waste the opportunity and successfully converted his reverse grid pole position into his fourth win of the season ahead of Rob Collard.

The Honda Civic Type-R driver is remarkably one of eight drivers who can mathematically win the crown.

"We were 40-points off the lead two rounds ago and now we've halved each deficit at both weekends. The problem is I can't just halve it next time, I need to get in front!" said Shedden.

"I didn't expect that, especially after race one. Silverstone isn't the easiest the circuit to pass on. I had a good run in race two. That was a cracking race. Every door that opened or nearly opened, I was in there and got through some other people's moves as well.

"I've made some good moves today. I've been round the outside of Brooklands a couple of times in race two, which really helped. You don't want to throw caution to the wind but race two and three was about digging deep to give myself an opportunity for Brands Hatch."

Shedden initially lost the lead during the final race but the defending champion hit back with immediate venom after making a mesmerising move around the outside of Collard at Maggotts.

"I knew I would have decent grip on the soft tyre and that car felt so hooked up. The BMW was also on the hard tyre, and also a RWD, I knew I needed to take my chance pretty quickly. I had an amazing run through turn one, took a couple of deep breaths and kept it going."

Running the softer compounder, the 37-year old said the balance of his Type-R allowed him to maintain a high cadence without hurting his tyres.

"The car was mega. I was staying off the kerbs and looking at the lap times thinking I needed to slow down but I actually wasn't pushing the car that hard. I could just square it off and look after the tyres.

"We could have quite easily been nowhere. If we didn't have the reverse grid it could have been a different story. One place further back and I wasn't making it."
