Hawk brake pads - worth it?

Do you mean BBP brakes? Back in the day Corvettes had K-H or similar made of aluminum and had serious corrosion issues and stuck pistons. Are you using aftermarket hubs? Ball joints and UCA are the same as what you have? All I'm trying to say is, maybe OEM is not as heavy as you think.

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.
