I'm looking for an extra set of 18" rims and want to remain in the M/SS (Showroom Stock) autocross class. I've found a set but the rears have two wheel sizes in the casting. One (my desired size) is 9Jx18-ET52 "B". The other, immediately below is 10Jx18-ET65 "A". Can you explain the contradiction? Thanks!
