I don't think this has run for awhile. I've been busy with work and going up to the Southside meet every fortnight. Not sure if anyone has carried this on most likely it has just died. I'm moving to Brisbane next week so I won't be attending any more.
I run 263/35/18s on my XD9s the same size. You will need to get your guards rolled. I had them without the guards rolled and standard suspension and they used to scrub in the rears. Rolled guards and stiffer suspension has sorted out all my scrubbing issues.
I'm definitely keen to give it a go. I think you volunteered to lead though. I can't be trusted. Lets give it a go this week then and see how late it stays open and how busy it gets. Atm there is only 5 or 6 of us turning up anyway so lets give it a try.
