Greg Keene and Amanda Sparks have dominated the 2007 National Dutton Series results, winning both Driver and Crew titles at the final round in Victoria over the weekend. The South Australian duo put together an impressive list of results, competing in Qld, NSW, WA and Vic.

Greg believes his choice of the dominant DUNLOP DZ03G tyres is the secret of his success. "We have been very happy with our choice of tyres this year" said the jubilant Keene. "the challenge will now be to continue to improve as the opposition attempts to catch up" he added.

DUNLOP tyres have won more events this year than all other brands combined, and fitted more cars in all classes as well.
