Kurt Kostecki will carry an updated livery on his Walkinshaw Andretti United wildcard entry when he returns in Sydney.
Kostecki and Tickford Racing's Thomas Randle will make their third wildcard appearances at the Sydney SuperNight on November 6.
It will mark Kostecki and Randle's first competitive running since June's Merlin Darwin Triple Crown.
SP Tools will take a major branding position down both sides of Kostecki's #27 Commodore.
Kostecki ran with prominent Mobil 1 branding in Tailem Bend and Darwin, with the 23-year-old scoring a top 10 at the latter event.
The #27 Commodore will continue to be supported by Mobil 1, Appliances Online and Middy’s Electrical.
The new-look car will appear at Winton Motor Raceway on Tuesday, with Kostecki to complete a rookie test day.
"It’s awesome to have SP Tools back involved in our team, we’ve shared some great times together previously, and car 27 looks fantastic," WAU Team Principal Bruce Stewart said.
"Kurt has definitely impressed us over the first two wildcard entries this season at The Bend and Darwin.
"We are looking forward to having him back with us for the Sydney SuperNight alongside Chaz and Bryce.
"I’m sure the test day tomorrow will be very valuable after being out of the car since Darwin.

"Equally we will all be working hard to ensure he is as comfortable as possible for the start of the event in Sydney so he can have the best weekend possible."
