Re: 1969 z28
We just talked about this on another thread here on camaros.net so you can do a search to pull it up. There is a chart there that lays out the "general sizes" for a 69 and it's 17 x 8 with 4.75" BS on the front and 17 x 9.5 with 5.5" BS on the rear. Tires are 235/45 17's front and 255/40 17's on the rear. That's the ideal size although with coil overs, spacers and different lowering blocks, etc., you can likely make the size mentioned work for you. I wanted a little more sidewall in the rear, so I actually ordered 45's (awaiting delivery next week). Do a search here and on YouTube for pictures of guys running the size wheels/tires you want to see how it will look, although watch out of rubbing on the inside of the rear tires and possibly some up front at full turn when you go with the larger sets.
ps: Welcome to Team Camaro!
ps: Nice car you have there. Got any pictures?
