I bought my 177's from Wheels and caps...correct offset and NO hubrings, the wheels are machined to the correct hub size (very Important!). 2 arrived with blems/minor defects. I spoke to the owner and they overnighted 2 new wheels, had them the next day. When I had the tires put on I had them spin the wheels and they were all great as far as balance. Boxes said "Keystone" on them, the tire guy recognised the name and said they've had very good experience w/them. Nice quality wheels, great company to work with and by far the best price. Highly recommended from my experience.
