Thanks again fellas.

SMC seems to be getting a pretty good rep.
I'm currently waiting for a reply back from Promatch, through their website, it seems they don't ship to Australia.

When I went that was on a Wednesday, but it was still a fairly good turnout.

I race at SRS 1-2 times a week. Closest track to me, but I haven't been home lately. I am planning on heading out there Friday for some practice before round #5 of B.I.T.D. I usually head out to W3 once a week.

No, I did not go to Comp., actually I do not think I have ever been to competition. Might make the 1 1/2 hour drive out there for the finals. Track looks nice though.

I have done a fair amount of research on buggy tuning and found this page to be the most comprehensive and easy to read. Scroll down to 5.7 and 5.8 to answer your question directly.

Holy Batman this guide is so readable, down to earth, and in touch with the masses, that if I ever enter the realm of 1/8 I'll seriously consider THE Car above all others first. Thanks for sharing, Cheers.
