They are a dealer for VTO wheels, which makes some old school Panasport and 4 spoke classic wheels. The good news, they custom drill for nearly any size. They are also stud centric with a steel sleeve that is not clearcoated to prevent marring or the wheel loosening (think retorqueing the wheels all the time, don't have to worry here).
I am thinking about getting the Classic 8 in 15x7 5x114.3 for the Cosmo. Black with the polished lip.
From what I have found online, the 15x6's are 14lbs. Not bad.
