Do you have big horns in the front? I was thinking of running big horns in the front and a set of 8 paddles in the rear.I run a set of paddles in the rear and it does great. My brother-in-law runs his big horns and makes it up tess just fine, of course I beat him because I have better traction. If I were you buy a set of rear paddles. I'm heading to Gordons next weekend.
I have no first hand experience with this. But, I was watching a video that said for every 1 lbs you reduce in rotational mass, you free up one horsepower. So, if you save 1 lbs on each tire/wheel combo on each corner of your machine, you are saving 4 lbs total and thus freeing up 4 HP. That is a lot of gain on a small machine like the RZR.you guys that run the bighorns really, really need to try out a set of lightweight paddles. skat-trak 8 pdl extremes and front buffs on dwt spun wheels. way, way quicker, accelerates faster, seems like i gained 10hp just bolting on paddles!!! prob 5-8 mph more top end too!
