I put the coils to the test today. Hauled a load of flat rock and cut stone. I'd guess there is probably about 2,500lb of stone on the trailer and a healthy portion of it on the tongue. This will be as much as I plan on towing or hauling with it. The rear compressed about 2.5" with the load on it. The coils handled the load much better than the stock coils would have.

No issues with unmodified stock flares with the 35s before the lift?

Didn't get to completely stuff the tires to full bump before I put the body lift on, but I did get them to rub a little with just the 18/60 coils. Lift alone won't increase tire clearance. It was fine for mild offroad and flex, but extended bump stops, flat flares, or a body lift is needed to prevent the 35's from rubbing at complete bump.

I want to keep my bump stops to a minimum and plan to relocate my upper shock mounts, so I leaned toward a body lift first. The body lift also increases clears in both the front and the rear where flat flares mainly provide clearance for the front.

A good read on bump stops, flat flares, and a body lift and how they effect tire clearance and the amount of bump stop/lift needed.

Building a capable off road Jeep is easy...building a street legal one that you can drive two hours away to wheel and then drive to work the following morning is the challenge.
