I just wondered what i needed to mount 28x10.5 outlaws on front and 28x12.5 in the back on c series wheels. Also what lift would be recommended: highlifter or berts dirt works? Berts dirt works is a site that seems to be focussed on polaris but also other brands. Check them out at www.bertsdirtworks.com They also have killer deals on tire/wheel pakages with free shipping. On their lift kits you can choose between a 1.5 or 2in. collar. I noticed on their 700(biggest quad ive ever seen) they have more than one of these collars stacked on top of each other. By the way i plan on going and trading my rincon on a 03 sp600 for 1800.oo difference this week.
