They do pick-up and drop-off, but don't know what the min. qty you'll need to have for this privilege.
Comment: Used them before for straightening out 3 sets of 18" TSW's and they did a great job. I have no experience with them on cracks wheels.

Comment: Used them to respray two wheels and they did a great job. We also use them to prep and paint our prototype parts. They also reapair and refinish a fair amount of OEM Porsche, Subaru, etc. wheels.
