I did this modification a few months ago. My goal was to maintain the lowest stance as possible. I also wanted to maintain factory ride characteristics. This is my second Raptor, had a Gen1 for 4 years before buying my 2018. After these upgrades I have had the opportunity to drive my truck fairly aggressively off-road with zero rubbing or other issues. In fact, I was conservative with my tire choice and wheel offset. There is enough clearance to run a larger 37" tire and more aggressive offset.
In front I'm running Icon's Attitude Adjustment Collars at the 1.5" setting. In the rear I installed Icon's Multi-Rate Leaf Spring set at option 1. I also used SDHQ 1" lowering shackles. This essentially gave me the factory height in the rear and raised the front 1.5". This gave me about a 1.5" rake front to rear. I also installed SVC's adjustable bump system.
Tire choice BFG KO2 37x17x12.5
Wheels ICON Rebound 17x8.5
I'm really happy with all of my choices. This forum was a ton of help, I spent hours researching my decisions. My truck is my daily driver and is used for towing duties (6,000 to 7,000 lbs) as well. I also like playing in the desert and I plan on doing trips to Baja.

After Suspension Mods and Factory Wheels and Tires

With 37's and Bakflip Bed Cover

With Bed Rack, 2 full size spares 10 gallons of fuel and 2 10lbs Power Tanks., settled 1" in back

Prior to modification tire rubbed on fender liner prior to full lock. Now I have at least 1 1/2" of clearance at full lock.
