FIGURED OUT THE OFFSETS! :0)
Thanks for any help...
I have a set of 18" Racing Hart M5 wheels, I have no idea what offsets they are. They came on a supra I bought a while back and I changed out the wheels, never got around to selling them. But before I do, I am trying to figure out the offsets... They fit the supra perfectly. Also, one of the wheels has a crack (probably from a pot hole) on the inner portion of the rim, so the lip isn't the damaged portion. I pulled them off right when I got the car and didn't notice any issues driving, only to find the crack after removing the tires... Is this repairable? How much do you think it would cost? I am wondering if I should just sell as is, or get them fixed and then sell them...
they are:
18x8.5
18x10
here are some pics.

It should tell you the offset on the inside of the spokes on the reverse side.

Thanks guys, I figured out the offsets, wish I wasn't in oklahoma. I just have no idea what reputable shop I can take it to for wheel repair like I did in TX.

I'd take it to a local wheel repair shop and have them take a close look at it. A crack like that probably means the rest of the wheel took a pretty good shot. A good wheel shop that knows what it's doing will spin the wheel up and have a dial indicator set up to measure run-out. Depending on the results, that wheel may or may not be repairable.
One thing is sure: a wheel failure at speed can result in a big accident; potentially taking out the entire car. Don't skimp on the assessment or pawn this off on some unsuspecting buyer who doesn't know any better!
