Front rim C6 offset is 56mm, tire size is 245/40/18, rim will push out 2mm or .080
Rear rim C6 offset is 79mm, tire size is 285/35/19, a spacer is required I am not sure what size, do some searches on the Forum & you will find that data, or someone will give that answer on your thread.
I am thinking about doing the same. After much searching, I found this post: https://www.corvetteforum.com/forums...els-on-c5.html. Looks like most people go with 1" or 25 mm spacers/adapters depending upon the manufacturer. The wheels that I am planning to purchase have the stock C6 tires: 245/40R18 and 285/35R19. Good luck.

I have a set of nice stock GM rims from a 2008 Coupe. Fronts are 18/8.5 and the rears are 19/10
I own a 1999 C5 with stock Fronts 18/8.5 Offset 58mm and the rears 18/9,5 Offset 65mm.
I would like to put the 2008 rims on my 1999. What do I have to do??? What size Spacers if any? What size Rubber should I use on the 2008 rims?
