Popular Frenchman Alex Premat will join Scott McLaughlin and Volvo Polestar Racing for another crack at the Pirtek Enduro Cup in 2015.
However, the decision on who will share with David Wall in the #34 Wilson Security-backed S60 is yet to be made, with current incumbent Greg Ritter one of a number of potential starters.
Premat, 32, drove full-time for the Garry Rogers Motorsport team in 2012-13 in a privateer VF Holden Commodores. He earned a reputation as fast but crash-prone and was replaced for the 2014 transition to a factory Volvo squad by Swedish Polestar favourite Robert Dahlgren.
Premat, who was a factory Audi sports car and DTM racer before his stint in Australia, drove GT cars in 2014.
McLaughlin and Premat's 2014 Pirtek Enduro Cup was highlighted by a second-place finish in the second race at the Castrol EDGE Gold Coast 600.
Premat's performance will be crucial if McLaughlin is to step up from the fifth he earned in the driver's championship in 2014, and fight for the title this year.
"I have a done deal with Premat, he is in with Scott and that won't change," confirmed Wilson Security Racing GRM team owner Garry Rogers.
"Alex did a very good job last year.He came to the enduros and it was unfortunate what happened at Bathurst but he did a very good job for us, so there was no hesitation asking him to come back.
"When he was first here he crashed and burned and wrecked and whatever, but the fact was he was always very fast.
"The boys were always fixing his car but they never sooked about it because they knew he was quick enough and when they are quick enough people respond."
On the situation with #34, Rogers said: "We are still looking at what our options are.
"Greg (Ritter) is one of the options. Several people are options.
"We are just looking at maybe we could do something else, maybe we couldn't. We are just chewing that around as a team to see what we think can give us the best result."
Premat's signing fills another piece of the complex enduro co-driver puzzle.
So far publicly confirmed for 2015 are:
- Jack Perkins in with James Courtney at HRT to replace TV-bound Greg Murphy
- Tony D'Alberto to share with Tim Slade in the Supercheap Auto Commodore for a second year in a row
- Paul Dumbrell to continue his pairing with Jamie Whincup at Red Bull Racing Australia
- Steven Richards also to continue in a Red Bull Commodore with Craig Lowndes.
A handful of co-drivers hopped back in their 2014 cars at the pre-season test -Jonathon Webb in the TEKNO Autosports Commodore, Alex Davison in the Erebus Mercedes, and Taz Douglas and Dean Fiore in the Nissan Altimas -though they are not officially confirmed for 2015.
Macauley Jones spent some time in Dale Wood's BJR Commodore, but team boss Brad Jones told v8supercars.com.au it was not yet decided whether his son would contest the Pirtek Enduro Cup.
