Defending Supercars champ Shane van Gisbergen has more race wins than any driver this season but knows he needs to improve one key area if he is to record back-to-back titles.
The 27-year-old trails teammate Jamie Whincup as well as Shell V-Power rivals Scott McLaughlin and Fabian Coulthard in the championship battle despite winning four of the 10 races so far this season - but admits his starts have been causing him some issues.
He was beaten off the line twice at the last round at Winton and has consistently struggled for parity, let alone making ground on his rivals in the opening couple of corners.
"It has never been my strong point but I've really been working on it and getting better and better," van Gisbergen said. "But then this last round I had a couple of shockers.
"It is something I need to keep working on."
