Will Brown conquers Bathurst with Toyota 86 racing series treble.

Young charger, Will Brown from Toowoomba in Queensland, has made it three-from-three with a flag-to-flag win in the final Toyota 86 Racing Series race at Bathurst.

The third victory finished off a remarkably dominant weekend for Brown who won the first two races after qualifying on pole at the iconic track on Friday.

Brown used outstanding race-craft to hold his lead over six laps, seeing off a determined challenge from invited driver Steven Johnson over the final few corners.

Johnson ultimately finished second, with another experienced racer, David Sieders from Sydney in third.

Racing was tight right through the 37-strong field, with the top six place-getters covered by less than a second at the finish.

Brown was thrilled with his 'three-peat' win, which extends his series points lead.

"It's been exciting, and three from three is great. We're really happy with the weekend," Will said.

"We'll have a pretty handy points lead heading into the last round at Homebush, but anything can happen. We've just got to take it race by race and try and keep it off the walls," he said.

Kiwi visitor Ash Blewett who finished in a fighting eighth place won his spot on the Bathurst grid as part of the prize package for taking out the 2016 New Zealand Toyota 86 Championship, and has thoroughly enjoyed the mountain experience.

"The whole weekend has been brilliant. We've managed to improve lap times by close to three seconds since Thursday, and ultimately push up into the top 10," Ash said.

"It's busy across the top of the mountain, and it's hard to pass, but the work we did on set-up really paid off. It's been great," he said.

Final stop for the Toyota 86 Racing Series in 2016 is the Sydney 500 at Homebush (Dec 2-4), with another entry in excess of 35 competitors expected.
