The results of race one made it mathematically impossible for Plato to win the title, leaving seven protagonists to duke it out in races two and three.
Race two - Turkington triumphs again
Turkington’s Subaru was laden with 75kg of success ballast for the second race, with Austin collecting 66kg and Cook 57kg. Both of the front-row starters opted to use Dunlop’s softer tyre compound for the encounter, as did Plato, qualifying on the outside of the second row in his Levorg with 48kg of ballast on board.
Turkington made another great getaway, while Austin was sluggish off the line and nearly came under serious pressure from a fast-starting Plato as they charged into Paddock Hill Bend. Cook slotted into fourth ahead of Shedden, Neal and Tordoff.
On lap four, Matt Neal slowed when the engine of his Civic Type R cut out due to a suspected electrical issue as he came out of Paddock Hill Bend. Then, as he limped around Druids at a reduced speed, he touched the MG of Ashley Sutton and was catapulted hard into the barriers, necessitating a safety car period.
Upon the restart, Shedden sliced past Cook at Paddock Hill Bend for fourth and set about chasing down the top three.
On lap eight, Plato grabbed second place by overtaking Austin at Surtees. Shedden took advantage of Austin’s lack of momentum out of the corner to steal third place on the ensuing straight.
Plato stormed up to the back of Turkington at an astonishing rate and on lap 12 made a feint down the inside at Paddock Hill Bend. With Plato out of the title running, however, he eventually opted to play spoiler for his Subaru team-mate, protecting Turkington from title rival Shedden and the chasing pack.
On lap 15 Cook barged his way past Austin at Paddock Hill Bend for fourth and Austin fell further back as he took a trip through the gravel and dropped behind Tordoff, Moffat, Jackson, Morgan and Ingram. On the next lap Austin limped into the pits and retirement.
Turkington was overjoyed with his fifth win of the season, with Plato and Shedden joining him on the podium.
The result leaves three drivers in contention for the title ahead of the final race of the season. Tordoff, fifth in race two, still leads the way on 295 points, just two points ahead of Shedden and ten points clear of Turkington.
Neal is mathematically in the hunt despite his accident, but has been ruled out of the showdown due to slight concussion.
Race three - Jackson wins, Shedden storms
The random reversed grid for round 30 handed pole position to Jackson, who had finished seventh in race two in his Ford Focus.
Moffat was alongside him in a Mercedes-Benz A-Class, with points leader Tordoff third ahead of Cook, Plato and Turkington. The Subaru man had a full 75kg of success ballast, with Shedden on 57kg and Tordoff on 39kg.
