Fo sho no flares, just roll and slam, looks mean. As for roof, for some reason I wanna say go red.
Also what size are those wheels and what they cost ya? (if ya dont mind me asking)
If you have rolled the lip in already, you may have to roll it back out, or just massage the guard out? Is amazing how far you can pull them out just by rolling and forcing them out, that should work on the rear, its the front that looks like it will be the mission, may have to flip lip out and shape/bog/paint.
