From what I’ve read, you can go with a wide variety of wheels (eg Apex), most suggest 18” is the way to go but tire sizes are limited in either 18 or 19 for 71Rs or BFG so you kind of need to know your preferred tires too.

I ran 71Rs at ~18 local Autox events last year on stock size 19” rims (I wouldn’t buy stock again ... at the time I couldn’t get confirmation 18” would fit, now I would go 18”). If you want to keep in BStreet class at SCCA, you need 9” and 10” wide, but local clubs other than SCCA may not care too much. 265 or 275 front and 275 rear seem to be a preferred option.

(You probably know this, but as soon as we add camber plates we lose BS class)
Thanks for the feedback! I must have thought that both width and diameter are +/- 1", but of course that's incorrect. I am thinking of going with the same setup as the LBB M2 in the B-street thread. Only thing slowing me down at the moment is the APEX guy saying that it won't work
