Factory hubs. Small ball joints and UCAs. These calipers are powder coated. I can see corrosion happening in an every day driver/all weather situation but I can't imagine it would be an issue for me. This is a nice day driver that spends 85% of the time in a well-insulated garage. Maybe down the road but hopefully not any time soon. About two years ago I sold and shipped a whole '73-up disc brake set up and it 100 lbs for all the parts, not including rotors which were at least 25lbs each. I never actually weighed the SSBC stuff on a scale but just by handling it, the small stuff doesn't weigh anywhere near that.
