DISCLAIMER: THIS IS GENERAL INFORMATION, IF MACKIN DECIDED TO MAKE A NEW MOLD FOR EVERY SINGLE OFFSET THEN WHOOP-DEE-DO, I STAND CORRECTED, BUT THIS IS HOW IT USUALLY TURNS OUT FOR HIGH-VOLUME WHEEL MANUFACTURERS
not necessarily. a wheel manufacturer will usually make molds for only a few faces at each diameter. then they will use those faces for a range of offsets, adjusting the backspacing to fine-tune the offset throughout the range.
basic example: 18" diameter wheel
8.5 width with a HIGH offset gets face 1 (flat)
8.5 width with a LOW offset gets face 2 (barely concave)
9.5 width with a HIGH offset gets face 2
9.5 width with a LOW offset gets face 3 (concave)
and so on...
so an 8.5 wheel with a +40 offset and an 8.5 wheel with a +45 offset would use the same face, they just mill an extra 5mm off the mounting surface to adjust between +40 and +45..
so for your situation, it is doubtful to me that volk would make a completely new face for the 5mm difference between +40 and +45 at the same width.
