Hoping Dave or someone with a similar set up will chime in with pics and advice. I have a 73Z with stock Z/28 rims. I have Pro-Touring F Body springs front and rear along with the Pro-Touring F Body solid body bushings set on the low setting. My question is..... what is the best tire/size for my set up? I only want to do this once. I have reviewed the tire sticky. Please help.
