Aussie Racing Cars
Kel Treseder executed a clinical final lap pass before hanging on to win Race 1 of Aussie Racing Cars on the Gold Coast by 0.0556s.
Joel Heinrich skipped almost a second clear from pole position before the top three of him, Justin Ruggier, and Treseder began to tighten up.
When Ruggier made a slow run off the Beach Chicane on Lap 6, Treseder was able to pull alongside and make a straightforward pass as they turned onto Breaker Street.
Heinrich had been able to re-establish his one-second lead as they battled but Treseder caught up again and the 2018 series winner found himself having to defend at Turn 11 on the final lap.
Treseder used the criss-cross on exit to pick off Heinrich up the road at Turn 12 and while the pole-sitter got a slipstream on the run to the finish line, he came up just short.
Series leader Ruggier drifted nearly six seconds adrift but retained third position, ahead of Josh Anderson and Kody Garland.
The next two races of Round 6 take place tomorrow at 0830 and 1250 local time.
