The MSR deal is a lifeline for Percat who has battled through a tough season and a half with Walkinshaw Andretti United.
He was long expected to part ways with the team at the end of his current deal, which was recently confirmed, and was known to be part of a group of experienced drivers in the frame for the MSR seat along with Scott Pye.
The 34-year-old has won out in the fight for the MSR seat, which could be the final full-time vacancy on the grid next season, should James Courtney and Aaron Love form an expanded Blanchard Racing Team line-up as expected.
Percat has history of success at family-run teams, having picked up race wins at both LD Motorsport and Brad Jones Racing, the latter proving to be a particularly happy home between 2017 and 2021.
The 2011 Bathurst 1000 winner will partner the recently re-signed rookie Cam Hill at MSR next season, taking over what has been a race-winning seat in Le Brocq's hands this season.
“I’m really excited to be joining MSR for the 2024 and 2025 Supercars seasons,” said Percat, whose last of his four Supercars race wins came in 2020.
“I really like the way Matt runs his team and the family feel and culture he’s got going on there. It only took a few minutes to realise I was keen to join the team when I met with him at the workshop and saw the team for myself.
“It’s really positive and I can’t wait, but also for me personally, it’s cool to be back aligned with the GM family. Obviously it’s a big part of my family’s history and my love of road cars started thanks to Holden, so it’s very cool to be driving back under that banner.
