Jimmy is the only one I know of in Greenville. I think they have a Hunter alignment rack, but I doubt they have scales for corner balancing. You usually need to find a more race oriented shop for that service. I think the next closest regional NSX expert is Eiffel in Atlanta, but they might not have the equipment for corner balancing either.
I know some people with german cars recommend Protech Motorsports on State Park Rd, but I'm sure they don't have NSX specific experience. They might only be willing to work on german stuff anyway.
There is also a new suspension/alignment shop opening up on Garlington Rd across from GE called Pompeii Motorsports. They are brand new (not sure if they have even opened yet), but I'm hoping that it develops into a reliable shop. Too early to call right now.
