Why mess about with wimpy 15s and even 17s?
Here's my great old 1979 Arntz sporting 18X8 fronts and 20X10 rears!
You have to hand it to Steve Arntz. Thirty-five years ago he was making cars capable of running 15X12 rear rims. Even with these 20" monsters have a look at the interior room afforded by the Arntz design and the inboard Jaguar brakes.
Actually these wheels live on my son's Chevelle but we thought we'd try them on for size, just for fun. They fit and they're driveable but it makes the old lady look somewhat cartoonish.
Here she is with her usual 15s, 255 at the front and 295 rears. I'm not sure why the fence in the background looks distorted?????
