A wild rollover for Aaron Cameron has brought an early end to the day’s sole ECB SuperUtes Series practice session at Queensland Raceway.

Cameron squirmed in the Turn 1 brake zone before hitting the gravel trap sideways in his Peters Motorsport Mazda BT-50 and flipping.

Car #95 rolled three times before coming to rest on its wheels, after which Cameron exited of his own accord from the passenger door.

The accident appeared to be precipitated by a mechanical issue with smoke coming from the bottom of the Mazda as the 18-year-old began to slow at the end of Dick Johnson Straight.

The final five minutes of the 20-minute session were lost, leaving Cameron second to team-mate Ryal Harris.

Harris was fastest after the first timed laps and improved twice more to take his BT-50 around the Ipswich circuit in a best time of 1:31.4523s, 0.3656s quicker than Cameron’s fastest.

Tom Alexander (Ross Stone Racing Holden Colorado) had not long moved to third-fastest, just 0.0269s slower again, before the red flag.

Craig Woods (Western Sydney Motorsport Toyota Hilux) and Tomas Gasperak (Team 18 Colorado) rounded out the top five.

Sieders Racing Team’s two new Mitsubishi Triton drivers Cameron Crick and Mick Sieders were sixth and eighth respectively, split by team-mate Matt MacKelden in a Hilux.

Ninth went to Christopher Formosa (Ranger Racing Ford Ranger) and 10th to Steve Wilson (Steve Wilson Racing Isuzu D-Max).

Ben Walsh was last of the 11 entries after his WSM Hilux broke its diff.

The SuperUtes are back for Practice 2 tomorrow at 0945 local time/AEST, before Armor All Qualifying and Race 1 later in the day.

Results: Practice 1
