Australian motor racing greats are urging the New South Wales government to boost Sydney's Eastern Creek Raceway.
Yesterday the government committed up to $35 million over five years for the Sydney 400, a V8 Supercars street race through Homebush to run for the first time in Dcember next year.
Critics of the Sydney 400 say it would be cheaper and less environmentally damaging to stage the race at nearby Eastern Creek.
Four-time Australian Touring Car champions Allan Moffat and Bob Jane are among the signatories on a petition calling for greater investment at Eastern Creek.
Other signatories include former touring car champions Colin Bond, John Bowe and Glenn Seaton, as well as Bathurst 1000 winners John French, John Harvey, Barry Seaton and Bob Holden.
The petition says expanded facilities at Eastern Creek are essential for the future development of Australian motor sport and road safety.
