They've finally arrived. BBS SR in Himalaya Grey. 17x7.5 +27 rear, with 16x7 +24 front double stagger, offsets include 18mm 5 lug adapters.
Narrowly avoided a backorder from Germany by a minor compromise in lower offsets. Tire sizes are locked in for maximum width comparable to my goals for suspension (stock for the moment). Overall, I'm satisfied in choosing something a little different for the Spyder. @bbswheels
