GRM V8 Supercar team owner Garry Rogers has revealed that crashes to the Holdens of his young guns Lee Holdsworth and Dean Canto at Winton and Pukekohe have left him with a hefty $200,000 repair bill going to Eastern Creek next month.

Rogers' team will repair Holdsworth's VZ Valvoline/Cummins Commodore, which hit a concrete wall backwards at 150kmh at Winton on Sunday, and keep his partially built VE replacement car for completion and debut later in the series.

"We've cut the back end off and got 14 guys working non-stop to fix it," Rogers revealed, "It's been some really expensive damage and money doesn't grow on trees anymore, but we will do it, do it properly and test it before the Sydney race."

If anything, Rogers was more concerned about his young charger, and happy to report that Holdsworth was on the mend.

"Lee's pretty knocked around, but he's okay and fortunate he went in backwards as the seat cushioned him against massive G-forces," he revealed "He's one of the better young drivers around and had a terrific year so far for us. I know he'll come back and perform even better despite this set-back."
