C4-C5 brake conversion question
I know this has been asked; however, the search function is not working. How large of a spacer do you need to use C5 brakes with a 88-96 C4 non-ZR1 wheel?
I plan on getting some aftermarket wheels for the street later but for now I plan on using my stock sawblades. Thanks.

Check her performance nut, this was a paint to find, thanks to the search not working.
But it looks like you need 1/8" SPACER to clear. If you are going to use ADAPTERS, I don's know what you would want to use or what the wheel alignment w/body will look like (see page 2 of post for an idea...sort of). But I would asssume you would want as small as you can. Since you only need ~1/8"
AZc4Guy,
If performance nut doesn't want em, I might take them. Are they 1" for sure? Or might they be 0.75"
But by all means, he has first dibs.

The sawblades are for the street, I have a set of Z06 wheels for autocrossing and road courses. Thanks again.

Update
I called VBP today and talked to them about the conversion. Several things I didnt know where explained:
-Different companies made the stock sawblades. This is why some guys dont need any spacers and others need huge adapters to make the stock wheels fit. Is there a way to find out who manufactered the wheels on my car? If so, anyone want to list which manufacturer wheels you have and how big of an adapter/spacer you are using?
-On my application (1991), 1995-96 or C5 SS braided brake lines will work. I asked the difference and was told that if I used C5 SS braided brake lines to check clearances.
-VBP doesnt recommend the bias spring to be installed right away. I asked about the increase in braking ability in the front. I was told that unless I drove it on the track (which I will) and noticed that I indeed needed more rear braking, not to even bother.
-VBP is willing to modify their Corvette Sports rotor package to work with those who installed the C5 conversion. http://www.vbandp.com/detail.aspx?ID=565 They didnt say if their would be a cost difference but they did say you had to order it by phone.
That is about it.

Sweet!
Thanks for the update and I clearly had no clue about the sawblades. I only knew about that discrepancy with the early C4 (84-87) wheels. Where the manufacturer was switched and some can run them some can't.
Perhaps there is confusion here?
Or maybe GM switched again like they did in 84-87. I don't know.

Did they really need three manufacturers to keep up with production demand? Wow.

Ok cancel what I just said.
Dayum!?!? Three?!?!
So I am geussing you will just put the C5s on and then test fit the sawblades you have and if they work great, if not. Spacer time?
What did they recommend if they didn't fit?

VBP didnt recommend anything along the lines of spacers/adapters. The only thing recommended was buying wheels that are known to have sufficient clearance.
