My '64 GTO has a set of custom-made steel wheels, powder coated gloss black. The wheels centers were removed from a set of 1956 Chevy 15X5" wheels and welded into new steel rims.
The combo consists of 15X8" rear wheels (3-1/4" backspace) with 275/60-15 Firestone Indy 500 tires, and 15X5" front wheels (3-1/8" backspace) with 205/75-15 Kuhmo touring tires.
The rear end is a Ford 9" that has been narrowed 1-13/16" per side, it measures 56-3/8" wide from drum to drum. The stock rear was 60" wide. The rear wheel wells were not cut or rolled to fit the tires, but the inner wheelhouse was hammered a bit at the very rear inside bottom corner for clearance.
The rear springs are new regular-ride coils that have been cut down by 3/4s of a coil to lower the car, Air-Lift airbags (pumped up to 10 psi) are installed in both springs. Front springs are new 1967 Firebird V8 springs, they lower the front without any mods.
