Allen has had close ties to DJR over the past couple of seasons through a development deal of sorts.
That led to a wildcard appearance for DJR at the Bathurst 1000 last year alongside Simona de Silvestro, before Allen was promoted to the ‘primary’ enduro line-up this year.
He was also closely linked to a full-time promotion with DJR next year, given current DJR drivers Anton De Pasquale and Will Davison are both off-contract.
News of the Grove deal has prompted a response from Story who said he is delighted to see the 19-year-old find a home in the main game.
“We’re excited to have Kai join us for the enduros,” said Story.
“He’s had a lot of seat time with us over the past few years so we have gotten to know him well and his potential.
“He’s heading to a great team where they know how to win and he will do a great job there. Very excited and happy for him. Happy to see him in the main game.”
DJR’s 2025 line-up continues to be the subject of speculation, with ongoing talk that Brodie Kostecki could join from Erebus Motorsport.
