IRWIN Racing's Lee Holdsworth will mark his 100th race weekend start at the biggest race of the season, the Supercheap Auto Bathurst 1000. Holdsworth was given an extra special surprise to mark his 100th start with co-driver Craig Baird giving him a special pie in the face. Holdsworth will be one of the busiest drivers on Thursday driving the IRWIN Ford in the V8 Supercar practice sessions, before jumping aboard the prototype Ford Car of The Future during the dedicated co-drivers and Dunlop Series sessions. Holdsworth is driving the 2013 spec car as part of tyre testing at the Mount Panorama Circuit.
