Has anybody ran Billet Specialties on the Mazdog>?

Billet Specialties only have 18x7 with the biggest offset being 4in. Which i believe won't fit on a Mazda. But i swear I've seen them before on a Mazda.

you can oreder them custom made with almost whatever backspacing you want ... 18x7 needs a 5.75 bs to tuck on a bd mazda

i called and emailed billet specialties. They say they use a different drum then other billet company's. and the biggest offset they can give me is 4iches. But i swear I've seen billet specialties on Mazda's before.

i have 18x7 billet specialties on my isuzu they have a 5.375 back space.

Ok I looked and its only the GTP series that has a max offset of 4 inches. Wonder why they can't make that series with a bigger offset?
