OSV kit: not yet in production. Currently in the "pre-order" stage. they're looking for money from buyers to actually produce it.
*** Kit: IMO, it's the nicest looking kit so far, but plenty of people have had fitment and customer service issues with this choice. (The customer service issues and grudges being the main reason "***" is censored. Public conversation of these issues are generally frowned upon) PM anybody that's been here a while to find out more info. (hint: members page, then sort by "Join Date")
Andy's Autosport's Kombat kit: JUST started production withing the last couple of months. Only 2 people on the boards here have it (SkiBoarder311 is the only one with it installed, and his pic is on the website

Razzi kit is a ground effects kit. From what I understand, it replaces the rockers, but not the bumper covers. It is so popular because it is the least expensive. It has minor fitment issues, namely the front bumper piece...sticks out a little by the wheels, but not by much. But if you're willing to spend a little more money by molding it on, it makes it look much nicer.
