Larry Perkins hangs up helmet as Whincup signed.

Talented 21-year-old Jamie Whincup has been signed to drive a Castrol Commodore in this year's V8 Supercar endurance races at Sandown and Bathurst, which means that Bathurst legend Larry Perkins won't be driving.

Whincup was delighted to have received the call-up from team boss Larry Perkins.

"This is a huge opportunity for me. Larry's cars have a record second to none at Bathurst and I am looking forward to repaying the faith Larry has shown in my ability with a good result at the mountain," Whincup said.

Winner of the Australian Formula Ford Championship in 2002, Whincup drove a Holden Commodore for Garry Rogers Motorsport in last year's V8 Supercar Series.

The appointment now fills all Castrol seats and confirms that Perkins himself will not participate at Bathurst this October. Drivers include father and son, Jim and Steven Richards, rookie Alex Davison, Paul Dumbrell and veteran Tony Longhurst.

"Last year was my last Bathurst race. I said it at the time, but probably no one believed me," Perkins said. "There are other priorities on the agenda and its time to stand back and give the younger blokes a go."

Perkins boasts a spectacular 26 year record at Mount Panorama including being the most successful Holden Commodore driver with six victories, equal most wins in succession (three) and equal most number of podium finishes (12) with a highest 46 per cent podium finishing ratio.

"I'll have plenty on my plate at Mt. Panorama this year keeping an eye on the Castrol team and our customer cars," Perkins added.
