Lucas Dumbrell Motorsport will split testing duties in car #3 at Sydney Motorsport Park today between Aaren Russell and Matt Chahda.
Chahda was denied a CAMS Superlicence to race with LDM this year after he was presented as its latest driver at the season launch in Adelaide.
The Superlicence is required by all drivers in Supercars to race in the main series as of 2017, with a mixture of age and results determining whether it is given to drivers.
Team-mate Alex Rullo has been given a provisional licence for 2017 despite also lacking the required results and being under the minimum age of 17.

While the team continues to work behind the scenes on finalising its driver line-up, Chahda previously declared to Supercars.com he is likely to remain with the team in Super2.
Russell is returning to the car after driving for LDM alongside Andre Heimgartner during the 2016 Pirtek Enduro Cup.
The Newcastle-based driver raced the first half of 2016 in an Erebus Motorsport-prepared Holden Commodore and is understood to have continued backing from long-term sponsor, Plus Fitness.
Both LDM Holden are today running in plain black, as they did during a private test at Winton last week.
An LDM spokesperson told Supercars.com the team is yet to confirm the driver of car #3 ahead of the March 2-5 Clipsal 500, but today will be used to help evaluate the two drivers.
Rookie driver Alex Rullo has confirmed his switch to car #62 after he was initially listed in car #3 on the season entry list.
Rullo will be engineered by Tim Newton, who ran Renee Gracie in her Super2 campaign last season.
