I'd take it to your nearest race shop and have them check/straighten it

rotor to rotor, front, rear, top and bottom

The problem I see with checking wheels or brake rotors is that they have to be straight and not have any run out. But for checking it at home it's the easiest way to do it. I like to check from the hub face using a carpenters sqaure. The best way is to use "lazers" but those setup tools are expensive.

I have tried many of the measurement methods and while they do work I find that it is easiest to look straight through the axle tube and see how straight it looks by eyeball. When I straighten a rear end I use this method because if you look from each direction you can get a good idea of where the bend is at. The third member, snout seals, and inner axle seals need to be removed in order to use the eyeball technique accurately. I can usually get them within a 1/16" by eyeball.

Usually a measurement is easiest to determine if it's bent while everything is still together. If you have to start straightening it then the eyeball technique will save you a ton of time.

For what's its worth, if the axle slides in easy with your finger only, it's straight enough to race. Or at least that what I do.
