Brown was particularly closely associated with a DJR switch at the mid-way point of the entire year.
Any lingering doubt over that has been put to rest last Saturday when Erebus announced new two-year deals for both Brown and Kostecki, locking the pair in at the Holden/GM squad before end of 2024.
An announcement on Davison’s future with DJR could come when the lead-up to the Sandown SuperSprint later this month.
When quizzed on the Erebus news, and what this means for his job security, Davison told Motorsport.com: “I haven’t been stressed at all, all year.
“There has been lots of talk, but we’ve just been focussed on our jobs.
“Most of us go along well, we’re getting results. There’s been plenty of talk, but I am getting on with my business.
“I’m touching individuals that know and individuals that count, and we’ll leave it at that for as soon as. There’s very little more to state.
“We’re pretty laid back, we keep all that stuff to ourselves.”
Davison has been around impressive form this season, currently leading teammate Anton De Pasquale within their qualifying head-to-head 12 to 11.
Both drivers have a win each and sit third and fourth in the standings, De Pasquale with the narrow edge on overall points.
