So, I’m the proud owner of a new griz and I have ordered a set of Outlaws. 28×9.5-12 for the front and 28×12.5-12 for the rear. 1.25" lug. I have a shim kit coming that has 2x 1mm, a .5mm and a .2mm. Being as my bday is coming up, my bro ordered an EPI mudder clutch kit (0-3000′, 28-29.5" tires), and my girlfriend ordered the EHS Big 3 kit for the ’14+ grizzly’s.

Now for my question. I run medium mud/muskeg and pretty fast trails with lots of hills. What size shims would be a good starting point to try at first? Will I likely over rev on the flat parts of the trail?

Any info would be great, thanks.
