Southlander Brendon Leitch is returning for fifth TRS campaign this summer and he believes working with the other drivers in his team will be key for getting the best out of his car.
"A teammate is one of the most important pieces of the puzzle," he told The Herald.
"The more you can work together with your teammate and push each other along I think that is where a lot of the time is.
"There is not a lot to change in the set up – the cars are what they are – apart from a few little pieces here and there."
Leitch is driving for the Victory Motor Racing outfit and will have American Cameron Das as a teammate this season.
"It is most important to have a very good teammate and I think I have at least one very good teammate this year," Leitch said.
