The turbo RWDs were keeping up quite well with the R's. Must be the 150kg or so weight of the AWD system counteracting any AWD benefits on very tight tracks. I have to say I was impressed also by the red stock M3. When he rocked up I was like, who the hell is this guy lol. Kept up very well on the twisties.
For those thinking of getting a CB radio for the next cruise, I really would suggest getting at least a 3W one (like the Digitech posted in the group buy), or even better a 5W one, like the $90 delivered-to-your door 5watt FD-450A or FD-460A off eBay. JamesK and I are extremely satisfied with these, and the price is around 1/3 of what you will pay in Melbourne. It was really obvious on the GOR cruise that the lower power handsets eg., 0.5 or 1w ones were inadequate. I would say something, then would only get static in response due to poor transmission power from the person replying.
