Holden teams chasing splitter solutions

Holden teams will this week renew work to improve the front splitters and mounting systems on their ZB Commodores after a series of failures at Phillip Island.

The underside of the splitter protrudes further from the front of the new-for-2018 Holden than it did on the VF, which has caused headaches for teams in recent months.

Problems caused by the flex arose during pre-season running at Phillip Island, Queensland Raceway and Sydney Motorsport Park, prompting work to add extra bracing.

Splitters were relatively off the radar during the first three events, save for Jack Le Brocq’s breakage at Symmons Plains caused by contact with another car. 

They returned at Phillip Island, the second-fastest average speed circuit on the Supercars calendar boasting long corners and a high reliance on aerodynamics.

The ZBs of Nick Percat for Brad Jones Racing and Lee Holdsworth for Preston Hire Racing were the hardest hit, breaking two and three bars respectively and sustaining mounting damage.

, getting the bracing where it needs to be.

“It is quite a different design to the VF and at a high-speed circuit I think all of the Holden teams, from what I hear, have had some sort of issue over the weekend.

“Collectively, everyone’s got some work to do. Everyone’s got their own solutions, either working for themselves or working with GRM as the supplier for the Victorian teams, obviously Triple Eight do their own thing with their supplies.

“We’ll get back and sort it out.”
