5)Fork springs may be changed, no other modification of the stock forks is allowed

6)The rear shock may be changed to a commercially available aftermarket unit. The linkage must remain stock
It seems a little strange to limit fork mods so much (which would be pretty hard to enforce), but allow essentially unlimited shock mods. I would suggest saying that any internal mods are allowed, but the stock forks and stock shock must be used. That would keep the cost down (people wouldn't be able to spend $$$ on aftermarket shocks) and would make the rule easy to police via visual inspection.

I'd suggest looking at the AFM production rules as a model -- http://www.afmracing.org/content/view/31/49/
