I don't think we can break out each and every item that would go up for sale... but I'll be glad to help you out. If you go to the forum's listing; on the line where it says "Threads in Forum : Parts and Accessories" ... on the right side there should be a 'Search this Forum' button. That'll limit the search to this little section, and if you're looking for wheels, you can just type in 'wheel' and it'll find'em.
I dont think that a seperate wheel section is necessary. The vortex is HUGE, they deal with all years and modes so, they have like a million more people than we do.
I think that if we start seperating the parts section, the sub-sections would post so slowly. I think that if you are the type of person that only gets on the org like once a week or every other week, yeah there's alot of new stuff added to that section, but a good amount of the stuff in there either sits for weeks, or is sold within hours.
