I'v looked at the various smoothies, but am reluctant to use something without air holes for the purpose of brake cooling. I don't know if not having those air holes would be a problem. I have been hoping to find someplace that made reversed regular old steel wheels with those air holes. I would like to go to 16 inch at the same time, but if not, I can send my wheels off to Weldcraft and they will reverse and widen or narrow my stock wheels or go to a junk yard and get some old wheels and send them to Weldcraft. Might get pricey though!
