My CMC widebody came with 18x8" Boyds Junkyard Dogs in a 5-bolt Chevy pattern with 255/35ZR18 meats installed by the previous owner. They fill the wheel wells, and are one of the things I loved about the car when I first saw it. They have adapters which push the wheels outboard about 3/4". The rears rub the fenders lightly when I corner really hard, so one of the things on my to-do list is upgrading the rotors to 5-bolt Chevy pattern, eliminating the spacers.
