Well, I do not have any links, but I saw some parts on Wayne Matlocks 700XX at a race this past weekend. He had Laeger long shock arms on the front along with Elka shocks all around. He also had Maxxis Razr's on the rear. (Still had stock wheels though.) I do not know if any of this stuff is out to the public yet, but you could always call the companies and ask. The tires themselves I think are really rare, as Wayne only had one set. Front will not be a problem for wheels and tires.
Also, for those looking for a little more width, Honda front wheel spacers will fit on the rear. Wayne raced with them on his and had no problems. Looks like he was running the Rad Mfg type ones,(Bolt to the hub and then seperate studs for the wheel.) about a extra inch per side.
