Seems a little close. Vans states 1/2" clearance. Can't tell if you have that with the heat shielding off. I'd probably ditch the heat shielding since if there's rubbing, it'll wear through quickly anyway.
Another concern is that there's no flange on the aft/inboard corner to bolt through the 3.5" spacer Vans calls for. Also, there should be 2 long bolts through the aft/outboard flange and spacers.
