C6 Wheels on a C5

Will it work? I have brand new 2006 Z51 C6 Wheels and tires and I want to put them on a C5. Is it as simple as bolting them up?

RD,this is being discussed greatly on the Forum but it my opinion ,yes they will work. Of course, the sensors will absoutley not work and if you want TPS you will have to install the correct sensors for your year C-5. There have been posts that specifically say they will not work but I do not agree. I can supply you with the math, (comparsion of tire sizes, revs per mile, etc. if you need that info. I am not talking as an expert just giving you an opinion.
The overall dimensions (DIAMETER and CIRCUMFRENCE of the C-5 and C-6 are almost identical. I can give you the figures if it will help. I believe the offsets are close enough that when you caculate the section difference between the two it should work. I am in the process now of putting 18's all around from a C-5 on a C-6.
I don't want a disagreement with anyone who says they will not work. It is my opinion only. I suggest you "bolt them on " and try for yourself.

C5 Z06 17x9.5 front and 18x10.5 rear
C6 18x8.5 front and 19x10 rear
C6 Z06 18x9.5 front 19x12 rear

These are all positive and in mm's
C5 front 58
C5 rear 65
Z06 front 54

A member of our club has C6 wheels on his C5, and the C5 is lowered.

He has had the wheels on for some time.

PM me a phone number and email address and I will have Jay give you a call, or at least an email.

Jay does not frequent this forum, to my knowledge.

Bolt pattern is no problem, front offset is no problem, brake clearance is no problem BUT the C6 rear offset puts the tire and wheel further inboard, should clear but try a test fit if possible.

Had my C6 wheels on my C5 since I brought the C6 home. They fit perfect, no rubbing no problems.

Just stock runflats. The rear is 285/35/19 and I dont remember what the front is? They are also almost the exact same outside diam as the stock size C5 wheels and tires. I weighed them too if you want to know what they weigh.
