I also just recently installed the Corvette C5 Big Brake Upgrade package (from bigbrakeupgrade.com) for the front brakes. I actually have a '01 C5 as well and the plan is to be able to swap out the 17x8.5/18x9.5 stock C5 wheels and the 17x9.5/18x10.5 Z06 wheels (I just recently purchased) on both vehicles as I want. I have done much research and it seems I need 1.75" hubcentric spacers/adapters for the front wheels, but I am concerned about buying a pair on Ebay and having them not fit. Can anyone direct me somewhere that will have a guaranteed fit for this setup?

I found these on Ebay, but it states they are hubcentric to the hubs only and not to the wheels:

Any help is much appreciated...

 

The ones you have listed will work but are not ideal. You want some that are hub and bore centric. I run 2" spacers on my C5 set up but you can see and feel the difference

 

Thanks for the info. Could you tell me where you purchased them? The main thing I'm worried about is the center bore of the spacers fitting over the hub correctly.

 

I found these as well and they are hubcentric and borecentric but it mentions they may not fit a 92 Camaro due to the hub height:
All of them that I have found like this state that.

Any help or guidance is much appreciated.

 

did you find find out if those types fit? I’m looking for front hub centric 2” and worry if they’ll clear the hubs also.

 

Yes, those fit fine. They were a little tight but definitely fit when everything’s lugged up. Also, I had the big brake upgrade.

 

What size wheels do you have in the rear? 17x9.5 or the 18x10.5? 2" spacer on all four corners?

 

Right now I have the stock C5 wheels on the front and rear. 17x8.5 front and 18x9.5 rear. I set this up where I can swap wheels with my C5, which has the larger Z06 wheels on it.

 

Did you use the supplied lug nuts that came with the spacers?

 

Yes, I used the supplied open ended lug nuts to tighten the spacer to the axle/rotor and my wheel lug nuts to attach the wheel to the spacer.
