Just pick up some 15"x10" 5-bolts cheap and cut the 5-bolt centers out to accept your centers. You will have more tire choices with 15" wheel. We've made many sets this way. Why couldn't you use the wheels the center come out of?
stockon only lists one set of prices for everything......there website isnt right.....
I have bout some from Marsh Racing years ago verygood people to deal with.
