I am very pleased with the ride. It's definitely more firm than stock, but that's also what I was looking for. Much less body roll around curves and a lot less rebound bounce from the suspension over uneven asphalt.
A skinnier tire should clear no problem. My rub is extremely minimal with the 285/65R18 - like barely scuffing the sway bar enough to notice.
As for the lift, I'm not 100% sure how much I ended up with because I had a Rough Country leveling spacer on before installing these coilovers and don't remember my stock measurements. With the Rough Country spacer I was sitting about 39" from ground to fender in the front and out of the box my Fox coilovers had it sitting at about 40.5". I'm in the process of playing with the preload to find a height I want to stick with, but I'll more than likely end up around 39.5" to 40" in the front once I'm done.
Right now I'm actually sitting a little nose high with my front measurement being 40" and my rear at 39-39.5", but I do also plan on going with an add-a-leaf in the rear to help with sag and keep things level when hauling a load.
