Biggest Brakes for 17" Rim

[JMitch19]

I'm running 17's up front and 18's in the rear. I want to run 13" rear rotors to fill the opening better. I will be C6 Z51 brakes in the rear. The problem is the C6 Z51 fronts are 13 3/8" and I'm not sure if they will fit under my 17" budniks. If not I will run the 12.8" C5 front. If anyone could tell me for sure if C6 fronts will fit or not it would be a big help.

Thanks
