80 Regal with notched frame. the 10's stick out a little with the 5" backspace but a 9 with 5" backspaced would be perfect. I currently run 255-60 MT Drag Radials on 15x8. A nine and I could go wider. The phoot shows a 15x8 with 275-50
They can custom make any width and backspace you need. Also I believe Steve Caruso from Carusoperformance.com can make any width or backspace. Just takes money Stockton quoted me $300 per wheel for 15x10s
