Very generally, you will need 4" of bumpstop to clear 37" tires
So you can decide how much lift you want to do based on that.
To put another way, how much compression travel (if any) are you willing to lose to be a little lower. Keeping in mind advertised lift height is just an average, and yours will vary based on options on your rig.
Also know that, most coil packages are designed to level the jeep. That is the actual lift in the front is more than the actual rear lift.
A 4" lift brings all sorts of other issues, such as: camber, exhaust clearance, etc...
Honesty, flat fenders make all this so much easier. But I understand needing to keep mama happy.
