Report Aftermarket wheels/tires for Avanti in 1963-64 Avanti Posted September 1, 2014 I updated the links to the original photos.... Nice to see this forum is active again. I have been busy building a resto-mod 1978 Camaro for my wife. Here is an extra shot left over from the Cover photos I took before the final was picked. You can see the 13" rotor and 2 piston PBR caliper nicely in this shot. Tom Tom, Those are definitely some nice looking 2003 Cobra wheels on your Avanti... Can you answer a few questions for me: 1. What size tires (F and R) did you end up with? I think you stated 245/45-17. Is that correct? 2. What size wheels (F and R) did you end up with? I think you stated 17x8, but maybe you are using 17x9. Would the 17x8 size result in less front fender clearance problems? 3. What are the wheel offset dimensions for your front and rear wheels? 4. If you used any spacers on the front and rear, what are the spacer dimensions and where did you get the spacers from? 5. Which lug nuts did you end up using and who supplies them? 6. Would the Cobra wheels work with the stock 63 Avanti front disk brake calipers and stock 63 Avanti rear drum brakes? 7. Do you still sell the machined disk brake mounting adapters for the brake assemblies that you are using with these 2003 Cobra wheels? I am pretty sure you have previously answered at least some of my questions in various threads, but I thought it would be good to be certain and to have all of the answers in one place. Sorry for the extra work I am putting you through, but I am getting pretty serious about upgrading my 63 wheels (and perhaps brakes). Thanks!
