Supercars driver Brodie Kostecki has identified a major problem with the wheels that were used in 2025 that contributed to the controversial grand final incident between Broc Feeney and Ryan Wood. And it’s something Supercars officials are changing for 2026.
Opinion remains heavily divided after Wood spun Feeney around on the opening lap in the final race of the season in Adelaide. Wood tried to get up the inside of Feeney, but was pushed into the wall when Feeney moved over to block him.

When Feeney turned into the corner, Wood’s position sent the Triple Eight driver into a spin and to the back of the pack. Engine issues eventually got the better of Feeney, who lost the championship to Chaz Mostert despite a whopping 14 race wins in 2025 compared to Mostert’s four.
Some have accused Wood and Walkinshaw Andretti United of taking out Feeney deliberately to give teammate Mostert a better chance to win the championship. But Wood and Mostert have rejected that suggestion and stated Wood was simply racing hard and trying to win.

Feeney admitted he was also at fault as he didn’t need to defend Wood as hard as he did because Wood wasn’t even involved in the grand final taking place between the final four drivers in contention. Only Feeney, Mostert, Will Brown and Kai Allen were still alive under the new finals format.
The situation took another twist this week when Ford driver Kostecki identified an issue in the Feeney-Wood incident that’s been largely overlooked. Speaking on the ‘Lucky Dogs’ podcast hosted by Kostecki and Feeney’s teammate Will Brown, Kostecki revealed Feeney and Wood’s wheels interlocked because of a design flaw.
“I think everyone’s looking at the outcome because it was huge, but it’s because the wheels are shit,” Kostecki said. “Broc’s car was airborne from wheel-to-wheel contact.”

Design flaw in wheels that Supercars is changing
Kostecki had aired his concerns over the wheels earlier this year after an incident with Mostert. The Shell V-Power Racing Team driver was alluding to a design feature in the Gen 3 wheels used in Supercars where the spokes protrude beyond the wheel rim. According to V8 Sleuth, the problem was fixed in the initial design for the Gen 3 wheels, but they were later kept the same on review.
Because the spokes stick out further than the wheel rim, the tyres are prone to interlocking with those of other cars. Supercars officials have reportedly commissioned a revised version of the Gen 3 wheels where the spokes don’t protrude as far, and approved them for use.
Unfortunately for Feeney they weren’t rolled out this year. The new design will reportedly need to be shipped in from England, with Supercars awaiting confirmation as to when they’ll be available. V8 Sleuth is reporting that teams will be allowed to use them as soon as they’re available, although it’s believed they’ll be rolled out in phases.
