There's nothing fake about steel, but yes, the fronts are of the light alloy kind and the first pair of smoothie stealth types from Centerline right after they announced their availability. I can't remember the official name of them. I got 'em at SEMA years back and painted them gloss black as soon as I landed at JFK. LOL. Were lighter than the steelies by about 10 Lbs each IIRC.
The rears are regular Centerline Auto Drags with a custom punched aluminum hubcap to hide the rivets. Painted black and they were ready to fool the masses.
