Yeah that's what I thought. When I built my brackets I went one size up to the "heavy duty" Z51 brakes. Not all the way to the ZO6 since I have 17's and that would have been a tight fit.
I looked on the site for the other sizes, and they didn't show anything for even the ZO6, much less the Z51 option. Oh well.
C5, C5 Z06 and C6 base brakes are all the same setup. I run 17's with this setup, I think they are 12.8 rotors.
The Z51 is considered "Heavy Duty" option on that and most sites.
