z51 drilled rotors
yes, i believe the 06 model c6 with z51 option was the first year for factory drilled rotors. the c5 never came with drilled rotors, however , three years ago i replaced my rotors and because the rear rotor was so small looking , i went with 07 z51 drilled rotors, which are larger in diameter. they bolt wright up as long as you use the longer caliper bracket. looks great, feels out the wheel. my front rotors are stock size but drilled. ordered all the rotors from brake performance, no complaints here and it looks as if it could have come from the factory. i'm running factory polished thin spoke wheels . these rotors along with led tail lights are among the only mods i've done . i'm pretty much a purest ..............hope this has been helpful to you.

Drilled rotors were never offered on the C5 from the factory as 8VETTE7 mentioned. They were offered on the C6 Z51 models.

[QUOTE=yanmar;1589733779], i went with 07 z51 drilled rotors, which are larger in diameter. they bolt wright up as long as you use the longer caliper bracket. /QUOTE]
I assume by longer caliper bracket, you mean the bracket that would be on the 07 Z51 that the rotors were for? BTW, how much larger are they?

answer for jackthelad
the caliper bracket needed for the larger 07 z51 rotor would be the stock caliper bracket that comes with 07 z51 caliper/rotor. retain your c5 caliper but otherwise the parts ,for rear, are stock c6 z51 parts. as for the diameter difference , half or one inch, i don't recall , but noticeable even from a distance. if you are in the market for new rotors this is a good mod. if you go the aftermarket two piece rotors you're looking at a substantial investment in money. hope this has answered your questions but if not i'll be glad to help.

Here you go: The factory C5 and C6 "Base" model brakes are the same (Calipers, brackets and rotors) so this kit upgrades both the C5 and C6 Base brakes to the C6 Z51 brakes (rotors and Brackets) you will use your "STOCK" Calipers

Little info on sizing:
Corvette Museum website says the non-Z51 front rotors are 12.8 in. in dia. and are 1.26 in. thick, while the rear rotors are 12.0 in. in dia. and 1.0 in. thick.
The Z51 front rotors are 13.4 in. in dia. and are 1.26 in. thick, while the rear rotors are 13.0 in. in dia. and 1.0 in. thick.
Thanks,Matt
