QLD Challenge is a touring road event, with pretty minimal navigation (you need a navigator who also holds a L2) and some great special tests. They use private road sections (no public road closures) in Gatton College, Wivenhoe Dam, as well as some racetracks, autocross tracks, and go-kart tracks, and normally a motorkhana style test as well. It's great fun. Need to be road registered, and carry a 2kg minimum fire extinguisher (I think 2*1kg extinguishers are accepted too). I think its the 24th of July, but I'd have to check that. The highlights are definitely Gatton and Wivenhoe road sections.

Your brakes are interesting. Have you been at QR? How did they hold up?
I've already ordered 14" tyres, so I'm kinda locked-in to that course. I'm planning on going circuit racing next year, and that's the main reason for going up to larger brakes - they need to last 12 laps at QR which is rekowned for being hard on brakes. In a small capacity, light car, I want the brakes to still be at their best on the last couple of laps when some of the bigger, more powerful cars may start to struggle with tyres and brakes.
