Hey Eric, and welcome to the site. You do not have to hav other mods to do the clutch kit. On my Renegade, I am running stock SIZE tires, but they are terracrosses, 25 inch.
I noticed a lot of improvement when I put mine on. However, I am now about to really step it up a notch with clutch work. My primary and secondary sheaves are about to be shipped out to have the angles changed, the faces resurfaced for better belt grip and the weighting changed for optimum shiftout and power.
Have you read the Dalton review that I did for the
Renegade and the one that Battlegun did for the
Outlander 800?
The only mod I had done until last night performancewise was a slip on pipe. I will tell you that mine continuously impresses people how much it blows them away on a drag race. The low and mid range improvements are drastic and when the shift out occurs in the mid-range, it is like a missle.
I say go for it and don't look back.
Buster
