On a day of largely wet conditions, Maguire aced four of the six stages in his potent 2016 Dodge Viper in a blistering display around the North-West. The Burnie flyer has now forged a two-minute 23 second lead in overall standings.

Angus Kennard and Ian Wheeler have moved into second with Trevor Mcleod and Steve Glenney third.

Maguire also tops the Dutton Garage GTO leaderboard from Kennard and Wheeler with Tony Quinn and Kate Catford third in their 2018 Nissan GT-R.

"We've just been doing our thing and staying consistent," Maguire said.

"The temperature on our tyres came up too much on that stage and we had to nurse them and back off a bit."

Kennard is still pushing hard hoping for a first overall win at Targa Tasmania.

"We haven't given up trying to catch Eddie yet'" Kennard said.
