I know this may be similar to the "bus load of nuns" fear mongering, but I'm not doing another BMC.....
Having seen, firsthand, how it stops the tire in a head on collision, I appreciate it's function and had altered the method of "chopping" to a straight cut and flat 1/4" steel "cap", to maintain the width of the mount.....which was relayed that it still rubbed PS, locked and stuffed with a ~34" equivalent tire.
Now, having heard of the new directive at local dealership, where they've noted "frame damage" due to BMCs, greater cause for concern, from a resale standpoint, enough do that I may replace mine.
I know some in the LT crowd have detailed alignment specs to keep 35s off the fender well seam, which should work for OE width 80% of the time.
