David Brabham is looking forward to this weekend's first V8 Supercar endurance event of the year, having already senses the IRWIN Racing's team's hunger for success.

Brabham, who will co-drive the blue-and-yellow Ford at Phillip Island with series regular Alex Davison, flew into Brisbane last week ahead of this weekend's L&H Phillip Island 500, and is eager to hit the track in his first V8 Supercar appearance for nearly four years.

"It's fantastic to be driving at IRWIN Racing," the sportscar ace said, "I get a real feel that they're very hungry for success. It's great to be in that environment heading to Phillip Island, and I am very excited. I've been away from V8 racing for too long."

The American Le Mans Series pacesetter arrived direct from Toronto, having raced his regular Patron Highcroft HPD prototype at Mosport, and headed straight to Queensland Raceway to test the IRWIN Ford Falcon.

"A V8 Supercar is very different to what I'm used to that's for sure," Brabham admitted, "[The test was] all about remembering what it's like to drive one of these things. I'm not 100 per cent comfortable yet, as there's still quite a bit for me to understand, but we made a big step forward.

"I haven't driven these cars since 2006, so it was good to get back in and feel how different they are. I'm focusing on learning the car and learning the systems that are in place, as these little things can make a big difference."

Full-time driver Alex Davison is also looking forward to this weekend's endurance race, the first of three events that will see him co-drive with Brabham.

"We're really confident, we've set ourselves with realistic and not unattainable goals," Davison said, "At last week's test, David went really well and got better and better as the day progressed. I'm really confident for Phillip Island and especially for Bathurst.

"We're going to the two events as underdogs, and probably won't be high on a lot of people's lists of favourites, but I'm really confident that we are going to surprise a few people."
