As much as the original "bowtie" wheels are unique and a pleasing design, I wanted to switch to a more sporty period correct wheel. These StilAuto Pentastar wheels fit the
bill perfectly. They're very light magnesium, 6x13. I never considered going to larger wheels because of weight. And over 14" the wheels are out of proportion for the car, IMHO.
Unfortunately the selection of 13" tires is extremely limited, mostly all-season types and no performance tires are available. So I went for a light good looking wheel and sucked it
up for the tires!
