CHAZ Mostert will shift into Walkinshaw TWG Racing’s spare chassis following the heavy crash that took him out of the Bathurst 1000.

Mostert’s Mobil 1 Optus Supra suffered considerable damage when it crunched the wall at Forrest’s Elbow on Lap 156 on Sunday.

With a short turnaround to the Gold Coast 500 on October 23-25, Toyota’s homologation team has elected to deploy its spare rig for the Supercars finals series opener.

It’s a move which reunites Mostert with WR 029. He started 2025 in that chassis – then assembled as a Ford Mustang – before reverting to WR 028 mid-season while ‘029’ was sidelined in preparation to be converted.

Gold Coast will be WR 029’s first race meeting in Supra form. It won’t be the only ‘Frankenstein’ chassis in the field, with BJR 018 driven by Macauley Jones having been transformed from Chevrolet to Toyota last summer.

Mostert’s teammate Ryan Wood also endured two crashes at Mount Panorama, but his WR 030 is good to go for Surfers Paradise.

Mostert and Wood are the eighth and ninth seeds for the opening round of the playoffs, after which the title race will be trimmed from 10 contenders to seven.
