Saturday 15 March at 13:18 : Among Super Aguri's troubles in Australia this weekend is a lack of spare parts for its cars, struggling British driver Anthony Davidson says.

The 28-year-old remained dead last in the pecking order by a wide margin following the qualifying session at Albert Park, where he has not coped as well as teammate Takuma Sato with a very limited number of practice laps.

Davidson admits bluntly that the Japanese team's car, after a disrupted winter, is "not very fast", but Super Aguri has also been nervous to collect too much mileage in Melbourne.

"We are on the limit with parts," he is quoted as saying by Press Association.

"Every twitch I've had in the car, every moment you've gone through a rumble strip at the exit of a corner, you know you're risking it because (a crash is) not just going to affect us here but next week as well," Davidson added, referring to the Malaysian grand prix next weekend.

After dropping out in the Q1 cut, the former Honda test driver said he did not enjoy watching the rest of Saturday's qualifying session.

"When I saw the on-board footage of the top guys I felt like crying because it looks so easy. So goddamn easy," he told the Mirror.
