i got c5 wagon wheels that i want to put on my 67 camaro to be able to clear new disk brakes i got for the front. I am pretty sure i will need to run spacers but not sure how much. Wheels are 2 17x8.5" and 2 18x9.5"
Anybody have any idea?

EDIT:
i think i would need 2.5" spacers still not sure tho

I don't know the answer to your question, but a 2.5" wheel spacer sounds like a train wreck waiting to happen. Measure the backspacing, which is from the back edge of the rim to the mounting pad and post back. A 9.5 rim generally likes 5.5 of BS on these cars in the rear and an 8 in rim likes in the area of 4.75 on the fronts

i don't seem to be able to find the backspace specs for the wheels i got. I found that the front wheel got 56mm offset and the back ones got 61mm offset. I was reading the wheel sticky but not still not sure on how to convert those two into backspace numbers.

1.875"-2.0" front; 2" rear - depending on your brakes.

kinda brief, Mike?
Poster is kinda new, may not know you are running these on your 68...
Hey, cut me some slack! I'm up in Seattle, facing a drive south on I5 today through about six mountain passes that may or may not want chains on my '68. I have chains, but I seriously doubt there's room for 275-40-18's and chains on the back end of a '68 Camaro.

Anyway, go here for how to convert offset to backspacing: http://www.skulte.com/adapterfaq.html and this is the basis for my suggestions above:

I just nabbed a really clean set of those for $100.
That's the really nice things about using the C5 wheels: they're cheap, plentiful and easily replaced if needed. I've got one set with Nitto 555's for summer and another set with Michelin Pilot Sport All Season run flat tires for longer trips in possibly dicey weather. Once I wear out the rear Pilot Sports, I'll go with something like a 255/40-18 to have clearance for chains, if needed.

Chains, lol. Why not snow itres in winter (you drive your camaro in the snow??)?
If you're in Seattle in mid-December when a big winter storm is predicted to hit, you need to be back home in SoCal, and there are six mountain passes you have to go through to get to SoCal, yes you drive your Camaro in snow if you have to. I didn't need the chains (other than to satisfy the requirement that you carry chains) and probably would have just parked the car if it came to that.

I take my car on reasonably frequent, moderately long, road trips (2,500 to 3,500 so far), so I like to be prepared for all kinds of weather. My "long haul" tires are Michelin Pilot Sport all season run flats, but even they weren't up the the snow conditions I was facing.

I think your car looks great. I actually have a post about V40's going right now but am interested in the combination you are running. What wheel size front and rear, what tire size front and rear and how much adapter/spacer are you using front and rear. Also, any concerns about the adapter/spacers as I assume you have run them for awhile.

Thanks,

Jeff

The wheels are stock C5 Corvette wheels with the stock Corvette offsets. The fronts are 17" in diameter and 8.5" wide. I run a 1.875" bolt on wheel adapter and 245-45-17 tires. The rears are 18" in diameter and 9.5" wide. I run a 2.0" bolt on wheel adapter and 275-40-18 tires. The adapter sizes may vary a bit based on your brake setup.

I've had no issues with the adapters at all, but many chain tire stores won't work on a car that uses them. That's not an issue for me or most of us who work on our own cars.
