Geelong brothers Jason and Craig Domaschenz took out the Commodore Cup Endurance Challenge while the Formula 3 success was shared, in Round Five of the Shannons Nationals at Winton Motor Raceway. Six categories raced in the Shannons Nationals’ first ever visit to the Victorian circuit, which kicked off the second half of the 2009 season. The Domaschenz brothers won the Menzel Glass Commodore Cup Endurance Challenge and the Ashley Cooper Memorial Trophy.

Steve Owen and Tony Bates led the Domaschenz entry home in Saturday’s first 45-minute leg, contested in wet conditions, after race leader Brett Holdsworth slipped off-track and down to sixth on the final lap.

Bates served a drive-through penalty for jumping the start of Race Two, recovering with Owen to finish fifth.

Jason Domaschenz claimed the lead with roughly 10 minutes remaining and won ahead of Geoff Emery / Ross McGregor and Holdsworth / Ryan McLeod.

The result, along with woes for Nick Parker and co-driver Shane Price, gives Jason Domaschenz the lead of the standings.

Two-time Australian Rally Champion Simon Evans and Jeff Watters had a tough weekend, finishing 12th in Race One and retiring with brake problems in the second.

“We’re rapt with the result, it’s an honour to win the Ashley Cooper Memorial Trophy,” Jason Domaschenz said.

“Our team did a great job all weekend, it was a trouble-free run and Craig did an awesome job behind the wheel as well.

“This was always going to be a crucial round, getting the points lead is a nice bonus.”

British driver Joey Foster and Melbourne’s Tim Macrow continued their battle at the top of the Formula 3 Australian Drivers Championship.

Both drivers had a win and a second place from two, closely-contested races, while New Zealand driver Ben Crighton scored a pair of thirds.

Bonus points for setting the fastest lap in each race saw Foster add another two points to his championship lead, the advantage now 20 points.

“There was nothing between Tim and I on speed all weekend,” Foster said.

“The starts were critical, I wanted to get in front at the start of Race Two and nailed it.

“The championship is very competitive at the moment, every point is valuable and grabbing the extra two for fastest laps could make the difference at the end of the year.”

Making a cameo in the Shannons V8 Touring Car Series, Steve Owen starred early, romping to victory in Race One.

Terry Wyhoon got the lead early in Race Two ahead of Owen, before they both went off on Lap Three - Wyhoon recovered to win with Owen sixth.

Race Three and the round win also went to Wyhoon, ahead of Chris Smerdon, Adam Wallis, Mark Shepherd and Owen.

“I’m proud of our team, they did a good job running three cars this weekend,” Wyhoon, who moves up to second in the standings behind Wallis, said.

“We’ve been quick at the first two rounds but nothing had gone our way, it’s nice to finally get a result on the board.”

Victorian driver Tim Rowse took his Commodore to the Kumho Saloon Car National Series round win, ahead of Tony Evangelou.

Shawn Jamieson suffered gearbox problems in Race One, but bounced back to finish third for the weekend and extend his series lead.

Three different drivers took an Aussie Racing Car race win, with David Lawrence scoring the round win.

Series leader Kyle Clews was second, ahead of fellow race winner Adam Gowans.

Ben Porter scored his third-straight Formula Vee National Series win in style, taking out the second and final round.

Two race wins gave Porter the spoils ahead of Victorian Jack Le Brocq.

This weekend’s racing from Winton will be broadcast next Sunday, 28 June, on SBS’ Speedweek from 1pm.

Round Six of the 2009 Shannons Nationals will be held at Sydney’s Eastern Creek on 18-19 July.
