You can with the correct brackets. If you need everything, Kore3 specializes in retrofitting corvette brakes to gm cars. It's not all that thrifty from them however.

www.kore3.com

Depending on what the usage is, it's still the best economically to go with something like a Right Stuff Detailing kit that uses mostly factory pieces.

If you have a street car only that does not see open track use, where repeated stops take place, the factory stuff is more then up for the task. Especially if you're running on old style 15" wheels and the types of tires available for them.

The smaller c5 setups should fit most 17” wheels. C5’s has 17/18 staggered setup from the factory.

The c6 uses the same calipers but a larger disc.

If you decide to go with a factory type setup, you can also do the Wilwood d52 calipers which have a higher end look to them and are a direct replacement for the factory style single piston calipers.

The Right Stuff has a number of conversion kits depending on your needs for 15"+ or 17"+ wheels and w/ and w/o a 2" drop...

I can get the calipers free! If I user a smaller disc will they fit my 17" rims. Like 11" or 12"?

Mounting wise, the C5 and C6 calipers are the same. The C6 does appear to be a bit stronger because of the redesign of the cooling fins.
All pads are the same D731 for the front, D732 for the rear.
C6 and C6 Z51 are the same caliper, you just need a different caliper mounting bracket- Z51 is taller.
The rotor is larger 13.38 (C6 Z51) vs. 12.75(C5/C6), so a little more brake torque available. The Z51 rotors have the holes in them though- by now, there are some solid rotors available.

If you are going to convert to discs, you’ll need: brackets for either setup, rotors for either, pads for either, and a master cylinder/distribution valve for either.
The factory-style setup will require either machining your drum spindles or replacing them w/ disc spindles.

The Kore3 design for adapting Corvette brakes to your drum spindles will require a hub to mount the rotor. This is easily fabbed by using your front drum hub.
You’ll need to remove the brake drum from the hub, turn down the outside of the hub to fit inside the Corvette rotor, and replace the drum studs with longer ones.
Or they sell aluminum hubs. Either way, you now have slip-on rotor system that doesn’t require repacking bearing every time you surface/change the rotors.
The other benefit of the Kore3 vs. other brackets is Tobin designed his brackets so your wheels aren’t pushed out further.
You’ll need brake hoses that convert from SAE to metric banjo- he sells those at a good price.

I’m going to be doing a video on putting the Kore3 brackets on my 64 Tempest, but it’ll be a bit.
I do have some reference info on the C5/C6Z51 calipers/rotors/abutments on one of my videos.

EDIT* Upon reading further on Kore3's Billet Hub info, they DO move the wheels out .200" each side, so your track width is slightly increased.

I'm installing CPP 13" C5 brake kit on my 69 Firebird. I recommend you buy the ebay spindle but used better quality parts, like corvette C7 Hubs/bearings, brake pads, brake rotors, calipers from C5, C5, Zo6 or Wildwood. Jm2c
