Wheel spacer help

Anyone know what with wheel spacers I need to put C5 Z06 wheels on a 85. The rears are 18X10.5 and front 17X9.5 that I kept off my Z06. Also what size tires would work well. Thanks

1.0" wheel adapters on the 8.5" front wheels and 1.6" wheel adapters on the 10" rear wheels.

Edit: the above information is for the base C6 wheels...

Also, the stock C5 ZO6 wheels are 17x9.5 front 54mm offset and 18x10.5 rear 58mm offset.

I just put 11" wide wheels on the rear of my car and the inside of the wheels is REALLY close to the shock mount, so watch for that.

You mention Z06 but the dimensions you mention aren't correct for a C5 Z06. Are these maybe replicas? I'd suggest you find out what you really have "first"! Wheel dimensions are generally cast in the rear of the wheels. Post the information from the back-sides.

Don't do a thing before checking and posting that information. If there's no information on these then it can be also calculated using other dimensions. You might consider posting snapshots of the wheel back-sides.

What offsets did you use to determine these numbers? Very unusual numbers you've mentioned.

These are the wheels that came on my 2002 Z06 which was just destroyed by a concrete Redimix truck delivering concrete to my house for my shop addition. I bought the car new and the factory tires are still on the wheels but the car is totaled, 9900 miles on it, so I plan to use them on a 85 C4 which I am restoring.

My apologies, the figures I gave were for the base C6 wheels!...I edited my post.

To the Op...I'm confused?...You say you have a 2002 C5 ZO6 which was destroyed but, you Bought 17x8.5" and 18x9.5 ZO6 wheels?...The stock C5 ZO6 wheels are 17x9.5 front and 18x10.5 rear. Is this what you have?...

Anyways...this wheel fitment site is really helpful.
