Jamie and Warren Oldfield both go into the event full of confidence and have form on their side in the quest to be the new Australia #1.
Jamie has been a strong performer in recent national championships.
Back in 2011-12 he was second to American Steve Francis in Sydney.
Last season he led for much of the event in Kingaroy before eventually finishing second to Queenslander Darren Kane.
Jamie is currently second in the Perth Motorplex track championship after four rounds, starting the season off with a win, before taking a second and then another win.
At the Boxing Day Bonanza round he had his worst result of the season with a ninth overall.
Warren is the form local driver heading into the two-night show as he leads the track championship from Jamie, Marc Giancola and Brad Blake. Here this season he has won two events and placed second and third on the two other occasions.
His first visit to the national podium was back in 2006-07 when he was second to Brad Blake.
He was then third to American Steve Francis and Craig Vosbergen in Bunbury in 2012-13.
The Oldfields are just two of nearly 50 drivers who will contest the championship.
Drivers will be locked into qualifying, eight rounds of heats and two preliminary features on Friday night, followed by another round of heats, the C, B and A Finals on Saturday night.
Friday night’s racing will include the Pool Shop Group Speedcars and Alltools Formula 500s while on Saturday night the Formula 500s return along with the Wormall Civil Sprintcars.
