Try Greg Nolan. He sets up some of the quickest cars in Improved Production, Super TT and the Wakefield 300. He is on the central coast.
Rick Shaw in Sydney, he won the Production Sports championship in the SW20. Build them, set them up and won. He is very good. He is expected at MTC 2015. He will be available for testing and car set up over the two days.
Another guy is Rotor Master in Hornsby. Very switched on, was the quickest and best prepped SW20 at the Bathurst 24 hour 2002. He looks after a number of SW20's around Sydney.
