What size tires you gonna run with those 15"? You can cut or trim out the wheel wells. That is your call. I would do 2 compressors faster recovery. I run 2 DC7500 from airbagit.com They run about $320 ea. You could also find a 4x4 with the flared fenders and bed that would also help your tuck on the wheels also. But running 15" wheels you should have plenty of room. I have 16" Chevy trailblazer wheels with 204-45R16 tires on mine and have about a 1" left when layed out. I'm getting ready to flip my front ball joints to get a lower stance. I have dominator II bags on mine.
