PRO? Thats going a bit far.
HPI acutally make a nitro drift car so even if you contacted one of the local brisbane shops they should be able to get there drift tyres for you?
What brand car and motor is it? When i ran a RTR car i only ran 5% nitro. In my race cars i run 16% nitro 12% oil and the remaining % methanol, i also mix my own fuel because you dont knkow how long premixed fuels have been sitting on the shelf for.
