Not sure it is only a run flat force balance, but just a road force balance. The tire is balanced running on a roller to simulate it running on a road. That way the balance can correct tire to rim index (minimize runout), sidewall stiffness differences (re-runflats), as well as an out of balance tire. Much better balance for a tire with short sidewalls. If done right you will be a happy camper.

Hunter GSP9700 Wheel vibration Control System solves wheel vibration and tire pull problems that balancers and aligners can't fix

Got to add one more thing and that is a 4 wheel alignment at the same time and not to all of Corvette recommended specs. There is a better alignment to stop the inside edge of the front tires from cupping. I think there were specs posted on here at one time. Change of the camber to as close to zero as possible should negate the inner shoulder wear that is so prevalent. Toe, .05 left and right to help reduce scalloping of the tire edges.

This looks like the machine my favorite tire shop uses. If it is, I can't complain.
I assume most shops are using this sort of balancers. If not, they are probably behind the times.

On my last alignment 7yrs ago when I bought a set up new Kumho ASX tires, I had the front tire camber set to zero (0) and haven't had any inside cupping issues since. I'm just a cruiser and do alot of long road trips and no autoX or any other type of racing. I just replaced those tires after 53K miles. I got my money's worth!!

Well, I've had several balance jobs with the newest Hunter road force balance machines. Some are good others are not. Admittedly, a lot depends on the technician but these machines are designed to be reasonably error proof.

Then I ran into an engineer from Bowling Green who was having his personal Vette fitted with new tires. He told the shop to not do the spin balance but rather to do simply a static balance. His contention was that was the best balance process for a Corvette. He also told them not to use stick-on weights but to use clip-on weights as far out on the circumference of the wheel as possible, like the wheels come from the factory. I've never tried this but the engineer swore that it was the way to go. Just FYI.
