My brother used them once to have a new set of tires/wheels road force balanced and they turned out great. I don't know if they would have the lug-centric adapter, but it's worth a call and they are only about an hour away from you in Wolcott, CT. My 4Runner has lug-centric wheels and a local shop tried to balance my tires twice and both times were horribly out of balance. I ended up taking them to the dealer and they used the adapter tool and road force to get them spot on.
