Hey 76, check out Weld Wheels in the in RT-S Series. They have a wheel called the S71,,,has tons of width and backspacing options. Pricing in 15" is excellent, 17" $$$ is so so and 18" gets pricey. I bought a set 15x10.25" wih a 29/12.5 for my minitubbed Demon, very happy with them. Section width on my Sportsman pros is 13.5" fills the well up nicely. I had to go with lots of back spacing because of stock axle width. I was also limited in space where the quarter meets the wheel well. My build is in progress but later I plan to buy big wheel/low profile rubber as another cruising option to make more use of my corner carving Bill Reilly Suspension. I love Pro street and Pro Touring looks.
Your build and skills are Awesome!!
