Erebus Motorsport has announced an all-new driver line-up for 2021, with Brodie Kostecki stepping in beside Will Brown.

The Holden squad was known to have already signed Will Brown on a multi-year deal which would see him positioned to take a main-game seat in 2021.

It has now confirmed that Brodie Kostecki will also graduate from the Super2 Series to the Supercars Championship next season.

“It’s very exciting for me and for the team as well, we are all really looking forward to going racing next year,” he said.

Kostecki is already very familiar with the Erebus family, having driven alongside Anton De Pasquale in this year’s Bathurst 1000.

“I’ve been fortunate enough to be with the team for a while now and I think that’s a great thing going into next year.

“Though my first year in Supercars it will be my second year with the team, and we are all looking forward to making the next step together.”

The six-time Dunlop Super2 race winner, whose motorsport experience includes a stint in the US, will jump into the #99 Commodore.

The arrangement also confirms teammate Brown will move into the team’s #9 entry.

“Will and I will definitely push each other hard as we’re both very hungry and eager to get results,” Kostecki said.

“We are already part of the family and that’s really important; we all have a good time, but we are all still hungry to get results.”

The 23-year old has multiple main game starts under his belt, after also contesting last year’s three Enduro Cup events in his family’s Kostecki Brothers operation.

It was an attention-grabbing drive during this year’s campaign though that convinced Erebus CEO Barry Ryan that Kostecki was the obvious choice.

“Brodie is a hard-arse racer and exactly what we need in our team,” Ryan said.

“His experience in America is something many people don’t understand and as a racer he is no rookie.

“Brodie is more than ready and both he and Will are far beyond where we expect any young driver to be.

“We are really excited to have two young but familiar faces pushing each other and if we can give them the car then they can certainly deliver the results.”

Kostecki and Brown are set for some extra miles with the team looking to use one of their rookie tests in late January ahead of the Official Test at Sydney Motorsport Park.

The pair will line up together for the first time at Mount Panorama, February 26-28.
