Just do the math: 35" tire -factory tire 32" you get 3". Divide by 2 and it gives you 1.5" above the wheel in new height. So with 1.5" extended bump stops 35" tires will fit with a 1.5" lift with proper back spaced wheels 4.5" or running an adapter like the spidertrax to push the factory wheels out.
should you use shock exstentions or longer travel shocks other adjustments need to be made (generally bump stop length) to account for the added axle rotation that happens when you droop one wheel the the max and stuff the other.

Same as stock. Which is ok. But I'll be going to full coil system now that I added bumpers and weight my stock springs are sagging a lot
Bump stops will be needed to run 35's, for those I would just go teraflex as they have the cheapest and easiest extentions..
Not needed if running stock wheels and tires

The flashpaq is a tuner and recaibrates the speedo for the offset in tire size, I am currently running the fuel Econ tune and getting 18.5 mpg

I'd definitely recommend the Flashpaq too. It really helped give a little power back with stock gearing (3.73). Plus I get around 18+mpg in the summer. Flex is about the same I'm assuming since I never flexed stock. I just have the shock extensions now but am upgrading shocks in the near future. This picture is with no bump stops either.
