Rob Collard and Sam Tordoff will remain with the West Surrey Racing team for the 2016 British Touring Car Championship.
It will be Collard's seventh consecutive season with the team, while Tordoff stays there for a second straight year, having joined the squad in 2015 from MG.
Collard took three races victories in the the WSR-run BMW 125i M last year on his way to 10th place in the standings.
Tordoff won twice but finished in a strong fifth in the championship.
"It is great to have both Sam and Rob continue in the Team JCT600 with GardX WSR BMWs this year," said team boss Dick Bennetts.
"Considering that Sam has only done three years in the BTCC and only one in the RWD BMW, I reckon he'll really shine this season.
"Rob really lifted his game in 2015, to the point where three-time World Touring Car Champion Andy Priaulx acknowledged his pace on race day.
"The guys have been working really hard through the winter to move the 125i M Sports on to a new level, as we all know just how competitive the BTCC is!"
The team also unveiled a new livery for its cars for the upcoming season.
