Tasmania's Dodge Viper ace Jason White continued to bound away from the field in search of a successful defence of his Targa High Country crown.
Showing no mercy in changeable conditions, White and his co-driver uncle John White surged to a one minute 42 second lead in the race for outright and GT2 honours.
The Burnie team has topped 13 of the 15 stages that have been run across the first two days of competition.
Second outright is held by Paul Stokell and Kate Catford in their Lotus Exige 350 while Eddie Maguire and Zak Brakey had a solid day to be just over two minutes from the lead.
"The first stage (TS9 Mirimbah) was interesting and got us to wake up because there wasn't much grip," White said.
"There was just the right amount of moisture during the rest of the day for us and everything panned out well.
"I think there was one stage where another Viper (Maguire) pipped us but we can't complain.
"Our tyres are in good shape and we haven't used our new set for the front as yet so we are looking forward to the last four stages."
With Stokell and Catford putting up a decent fight, the big mover in the field was Matt Close and Cameron Reeves in the brand new Porsche GT3 RS.
Close, a two-time winner at Targa High Country, finished leg two in sixth.
Maguire, who was the only driver outside White to win a stage, is threatening to make it a Dodge Viper quinella.
