Thanks guys! I like the wheels too and really debated changing them but they have spacers to clear the calipers which just doesn't leave much stud for the lugs to grab hold of. That and 15" tires are becoming more and more difficult to find.
After much debate about leaving it alone, putting on Corvette Rally's or going to a larger wheel I decided to order a set of 17x8 Vintage Wheel Works V40 wheels for the car which will look like this on the car (+ center caps.) So it keeps that classic look but gives the car a bit more modern wheel & tire.
Plus, now I can show off all the new Wilwood 4 piston calipers that should show up later this week
