Need help fast. What rear brake change do I need to make so my 2006 Z51 will accept 16" wheels? I've been told that I only need to change the Z51 caliber mounting bracket to the std. one. Is this correct?

it will hit the ball joints

WOW! Who told you that? If you installed a standard caliper bracket on a Z51 rotor, you wouldn't even be able to reinstall your caliper because it would locate the caliper to low onto the rotor. The OD of the Z51 rotor is about an inch more than the standard rotor.

you would need the c5 or standard rotor

Thanks Dennis,
It seems like I need the complete std. brake assembly to include the rotor, caliber, & bracket. Is this correct?

There is no bracket on the C6 base brakes. I know for a fact because I just removed and sold mine.

Most 16" wheels still won't fit over the base (aka: non Z51/non F55) either so even switching out the entire assembly likely won't help.
As far as I can tell, only a set of totally custom made/specifically measured 16" rims (CCW, Bogart, Holeshot etc.) can be made to fit over a C6's brakes.

I would tend to agree. I'd give John at CCW a call. If anyone's done it I'm sure he knows the details.

I just received wheels & tires from John. The tires are Hoosier 28x14.2x16 Quicktime Pros. I'll purchase std. calibers & rotors tomorrow to replace my Z51 items. He assumed I had std. brakes. My new running gear will be an LSX 440" with an 88mm turbo, 4L80E trans, and a RPM Z06 3.42 rear. We expect to run @ Fayetteville, N.C. on 11-07-2009.
Thanks guys for your advice.

John is definately the man. You don't need calipers. The base and Z51 front calipers are identical. The only difference in the rears are the Z51 calipers have a slightly smaller piston size. You only need the rotors. Sounds like a bad-*** car. Post up your results.

16" fbody wheels wouldn't fit over the base brakes.

TCW

You WILL need the standard caliper brackets. If you use the Z51 brackets the brake pad/caliper will be placed to high on the non Z51 rotor.

Unless I missed something there are no brackets on the base calipers. Am I that blind that I didn't see them?

San, your picture does not show the caliper brackets.

Here they are. Large ones are front and small ones are rear:


Here's a rear rotor as it fits inside the caliper bracket.


Here's how the caliper flips up off the rotor during a pad change. Look close and you'll see the bracket.

Note how the bracket bolts to the spindle and the caliper bolts to the bracket. FYI this is called a "floating" caliper.

These are non Z51 rotors and calipers.

Thanks Tom. I just pulled off my calipers and sold them and didn't realize there was even a bracket. A picture is worth a thousand words.

I thought the std. C6 has smooth rotors with no holes or slots. The one pictured is the same as my current Z51.

TCW

The pic (bottom) of the Baer Eradia Speed rotor was just to show the location of the caliper mounting bracket. As a matter of fact that is a pic of a C5 I used to have. The C5 bracket and rotor size is the same as a non Z51 C6.

The other pics are parts off a non Z51 C6.

Anyone know if the Camaro bracket will fit a C6?

SgtRod

I didn't see this on the pic. Aftermarked pads don't come with "clips" or hardware. Do you need them???
