Brad Jones Racing is on track for another PIRTEK Pit Stop Challenge crown after four rounds of the 2023 Repco Supercars Championship.
BJR is first and second in the standings with its two crews, with Red Bull Ampol Racing and Penrite Racing just behind.
Triple Eight was quickest in the lane in Races 10 and 12 at the NED Whisky Tasmania SuperSprint.
Walkinshaw Andretti United, meanwhile, took home top points with a fast stop for Chaz Mostert in Race 11.
BJR continued to rack up points across both crews, however, setting the second- or third-fastest times in the three races.
The Albury team, which won the last three challenges, helped Heimgartner jump Tickford Racing's Cam Waters in the lane for second in Race 10.
Heading to the betr Darwin Triple Crown, BJR's crew on the Heimgartner and Bryce Fullwood entries leads from the sister Macauley Jones/Jack Smith crew.
With 13 points for a fastest time, however, Triple Eight's crew is within striking distance, just two points behind the second BJR crew and 11 down on the leaders.
Penrite Racing is the first Ford team in the standings in fourth, with teams' championship leaders Erebus Motorsport fifth.
The last seven sprint races across the Albert Park, Perth and Tasmania rounds have all counted towards the challenge, given the absence of the bp Ultimate Safety Car.
Regardless, BJR has finished either first, second or third in all nine sprint races in 2023 so far.
The PIRTEK Pit Stop Challenge will continue when the season resumes at the betr Darwin Triple Crown on June 16-18.
