rotors with or without rivets
Hello, I'm in process of rebuilding my first '77 corvette.
Question - the original rotors are held onto the bearing hub with rivets. A lot of new rotors I see available are only held on with the wheel and lugnuts not with the rivets.
Does it really matter with rotor is used, any advantages or disadvantages with/ without the rivets?
Not trying to be cheap just curious.
Thanks for comments in advance.

Mark the position of the old rotors so that they go back on in the same position if they are still serviceable.

the rivets were to attach them together and then true the rotor on a brake lathe. each rotor and/or hub is a tiny bit different. so we have to shim the rotors when replacing them. you can get the front rotors trued to the hubs at any shop with a brake lathe. but the rears are a different story. they have to be shimmed upon replacement. if removing rotor from hub for any reason other than tossing them out, make sure you match mark them so they go back on the hub the same way. and onto the same hub. you toss them in a box and you don't know which was right or left.
do you need to replace the rotors? because you can have the fronts cut at a shop with a lathe and can clean the rears up in place. rear brakes only do about 30% of your stopping.
