Jim, I put 'match marks' on my tires and rotors AND hubs. So when I take them apart, they can be put back together exactly as they came apart.
I use a small bottle of touch up paint to put a little red dot on the parts. Just a small dot almost not noticeable by anyone but me.
I also mark the location and weight of the individual wheel weights with one of those little label makers. If it throws a weight I can go and get one and replace it with no big hassle of taking the car in for a rebalance.
The reason for this is I've had a lot of aggravation in the past getting wheels/tires balanced correctly.
When I finally got a set that worked correctly, I matched marked the wheel/rotor/hub.
The Hunter GSP-9700 ? is the ONLY machine to even consider when getting balance done.
Unless you can find one of those on the car balancers. IMHO those are good to solve the problem of out of balance rotors.... then just keep everything matched up .... until you want to rotate your tires then you'd need to start all over again....
Actually all my methods/madness are devised to keep me from having to depend on someone else to do things to my Vette that invariably turn out wrong.
(and run my blood pressure up)
Good luck with getting your's right.
