Removed the mud flap bracket so the 35's don't rub.
Also tied the front side of the wheel well liners back to prevent rubbing.
I now have zero rubbing forward or reverse with 35x12.5's on 20x10 -18 Fuel Mavericks. (with a 6" lift)
I used Air Conditioning Aluminum Foil Duct Tape. I used to be in the A/C business and had some in the garage. You can get it on Amazon or at Home Depot.
It has been on the exhaust for 2,000 miles and holding up well.
Bora are the best quality spacers available and they will make any size you need. I had them make me a custom 8mm thick with 78.1 mm hub x 106 mm bore spacer to fit my Fuel Maverick wheels.
I recommend their Hub Centric/Wheel Centric Spacers for a perfect fit.

Looks good. I ordered my BDS lift yesterday, hoping to have it installed next week.
I went with Fuel Mavericks, 20x10 -18 with 35x12.5 Ridge Grapplers.
I have the Motofab 1.5" level with 20x9 +1 Fuel Mavericks and 305/55R20 Ridge Grapplers.
I did not have to trim or modify the mudflap and have no rubbing so you should have no problem with a +20 offset.
New shoes:
Fuel Maverick 20 x 9 +1 (No Spacer required)
Nitto Ridge Grappler 305/55
The Nittos are a huge improvement over the Duratracs, much smoother and very quiet.
I have only heard the popping sound while washing my truck not while driving. When I spray water on the roof I do sometimes hear a loud "popping" noise.
