Default Question about C-6 Wheels

I put C-6 Z51 brake package on a C-5 and then I found out that the C-5 wheels would no longer fit. So now I’ve put stock C-6 wheels with BF-Goodrich tires.(Front) 245/40ZR 18 (Rear) 285/35ZR 19. I then wound up putting a ¼ inch spacer to correct the offset on the front and a ¾ inch adapter to correct the rear. They look really great now they set real close to the out side of the finder wells. I also had to change the wheel studs on the rear from 1 ½ inches to 2 ½ inches. However wheels are now one inch taller. Does anyone know if there is an easy fix that can be done at home for the speedometer difference? Or does anyone know how much the speedometer difference might be? It also has HUD, I don’t know if that makes any difference or not.
Thanks

If your tire diameter is different you will need a computer adjustment to get the correct speed.

Here is a tire size calculator that converts to MPH differences.

Kindly provide information regarding the stock c6/Z06 wheels. Will they fit on a 2007 C6 or do I have to go aftermarket?
What is the widest tires that can be installed on a stock C6 front and back without it overlapping the fenders using the Z06 style rims? What company sells aftermarket Z06 wheels? Mahalo for your assistance.

Check out the Corvette Garage, they have the applications you need and their website lists the tire sizes and offsets...

Give Nate a call, he is great to work with...

Thanks for the feed back, I checked it out and the milage is so minor that it's not even worth bothering with.
Thanks again Chuck
