The brushed aluminum portions do rise off side of the rims and will scrape curb if given the chance.

I've had inquiries on the calipers.

They are the stock calipers painted with "caliper" paint from local Auto Zone parts store. I did take my time in soaking with simple green, scrubbing, rinsing and drying, masking any and all area not wanting paint, while still mounted. I found using a light sanding primer before applying paint, provides best uniform clean application.
