Jeff: Bought the G2 paint system off Ebay. $34.95 plus shipping and handling. Listed for mustangs of all things.
Bob: Bought them from
www.wheeldynamics.com They have the correct offsets for the Boxster application. Paid $995 for the rims, and he mounted and road-force balanced the PS2's and then shipped them to me for $2,150 total price.
