What hub bore should I be looking for and is it a big deal that I would be using a ring like its pretty normal for people to have to use a rings?
Yep, get rings and make sure you torque the lug nuts as much as possible with the tire off the ground. I will get roughly 80 lb ft off the ground before letting a small amount of the vehicle's weight on the tire to then finish to the desired torque. This step avoids the possibility of the wheel being fastened slightly off center (not likely with rings but still a step worth taking, critical without rings).
Another step many skip is to clean the hub face on the brake rotors and mounting face on the wheels before mounting new wheels or rotating wheels. This makes sure the wheel is mounted properly avoiding a possible vibration.
