Anodized aluminum Mounting Brackets BBK in winter/salt
 

I am thinking stoptech BBK because of dust boots for winter/salt use. But they have, as all BBKs, Hard Anodized 6061-T6 Billet aluminum Mounting Brackets. Are these corrosion free or is a liability?

Imho from rust rather two piece rotors may suffer. So if mostly road use is considered, yeah, check if calipers have dust boots & one piece disks (heavier though, and possibly more expensive wearables).
IIRC there were few guys that used track BBK kits like Essex even in winter/salty environment, but at very least they cleaned/washed them very often.
