C7 Z06 front brakes for $1,150 + pads! (and rear for another $1040)
Using a similar approach to Dropspeed's cheap CTS-V/ZL1 brakes thread, after a thorough search, I found all the parts I need to get J56 brakes for my Z51 for much cheaper than what the kit is sold!
Front rotors:
Z51: 345x30 mm (13.6x1.18") 20.2 lbs.
Z06: 371x33 mm (14.6x1.3") 23.8 lbs.
(Z06 front caliper is about 1lbs heavier loaded; 14 lbs vs. 13 lbs)
Rear rotors:
Z51 rear rotors: 338x23 mm (13.3x0.90") 18.1 lbs.
Z06 rear rotors: 365x25 mm (14.4x1.0") 24.8 lbs.
Girodisc Z06 rear rotors: 16.7 lbs(!!!).
IMPORTANT:
Remarks:
If you'd like matching rear Z06 brakes with their awesome 2-piece rotors (pads are same for all C7s):
Front rotors:
Z51: 345x30 mm (13.6x1.18") 20.2 lbs.
Z06: 371x33 mm (14.6x1.3") 23.8 lbs.
(Z06 front caliper is about 1lbs heavier loaded; 14 lbs vs. 13 lbs)
Rear rotors:
Z51 rear rotors: 338x23 mm (13.3x0.90") 18.1 lbs.
Z06 rear rotors: 365x25 mm (14.4x1.0") 24.8 lbs.
Girodisc Z06 rear rotors: 16.7 lbs(!!!).
IMPORTANT:
- Amazon uses algorithms to change price depending on demand (this very thread increases prices; imagine a world with Amazon being the only seller!). If the actual prices at Amazon are much higher than listed here (it oscillates a bit), search elsewhere.
- When I had to buy a replacement part (damaged one of my rear calipers), the best price I found was actually at an online dealer (23198739).
- Calipers:
- Black left: $273
- Black right: $262
- Rotors: $253 x 2
- Hoses (for J56):
- Driver side hose: $22
- Passenger side hose: $39 (shipped)
- Front brakes pin kit(18K2108X): ACDelco $18
- Query at online dealer (cheapest I found on 8/24/2018) for alternative pricing is here.
Remarks:
- I picked black calipers since Z51 comes with those. You can pretty much order any color; pricing may vary a little bit per color chosen.
- I did not include stock pads since I will buy track pads for my use (Raybestos ST47s). If you want the stock pads, I believe its part number is 25940447, costs $235.
- Amazon is currently low on stock. This happened last year for those who wanted to buy CTS-V components as well, but people got their parts in a week or two, even though the automated estimator states 1-2 months. Nevertheless, if you're in a hurry, this option might not be for you. I just ordered my kit tonight, so we'll see how long it will take.
- I could not find the pin kit number from C7 online parts dealer sites, but since I know that the calipers are identical to CTS-V/ZL1 units besides pistons, I used their part number. It must be the right part, but wanted to mention since I looked up different catalogs to find it.
- WARNING: GM says these brakes don't fit stock base/Z51 wheels; you might need to run a small spacer (just a few millimeters) for the required clearance. I intend to run a wide wheel set for track, but will definitely try them on stock wheels, too.
If you'd like matching rear Z06 brakes with their awesome 2-piece rotors (pads are same for all C7s):
- Rotor: x 2 = $300.25 x 2 = $600.50
- Calipers (black): , = $219.31 x 2 = $438.62
- Total: $1039.12

I too am very interested in the results. It looks like a great option for track days. I am hoping your stock Z51 wheels will fit without issue.
Thanks for posting this!

I'm also going to order track wheels, so this is not an issue for me. I'm leaning on CCW's TS12 monoblock wheels, and CCW said they should clear the Z06 brakes. They're very secretive on their offsets until the payment, but my calculations show that the following should fit well:
18x10 ET56
19x11 ET73
We'll see!

Thought that was true for the CCB's only?
GM is kitting this up and selling it themselves for Z51 owners and I do not think it includes any tune changes.

The instruction sheet says lists these kits for off road use only. May on a street car, they may be fine but on a track car with good pads and a set of sticky DOT tires, they will not. It's not a tune change, per se, but a different calibration for the ebcm

In other words, the brake balance is always a moving target at all times, and it keeps changing per traction and as the heat builds up on the pads. Even if the car is bone stock, it will keep changing since the fronts will heat up much faster than rear brakes at a road course track, and their friction co-efficient will move. Rest assured, your EBCM can adapt to all that with no issues. If it were an issue, GM would never offer it as a kit.
Keep in mind, brake upgrade packages like this is offered by many manufacturers. GM also offers the very same C7 Z06 brakes in ZL1 branding to the regular Camaro SS owners; it works great with no issues. When it comes to Camaro V6 owners, though, you need to change the brake master cylinder for correct brake pressures.

Not to start a pissing match, but my information came directly from a GM brake design engineer and also from Brembo. Again, it may work fine for most all street applications & most drivers, but in a road race situation with good pads and say, Hoosier A6's or A7's, the cal is incorrect. I can't vouch for Camaro applications, but with the Global A architecture of C7's, flashing a Z06 or Z07 cal in a Z51 vin can't be done.

In short, GM is using these brakes on Z51s for a race series. There are differences in programming, but they are insignificant until the car comes with a much better tire (like Z07). As such, you need not worry. Gm certainly doesn't : )

So this so called ebcm change and ice mode. Why wouldn't this happen when a wilwood or AP front kit goes on a z51 car with slicks? A few people have done it with great stopping power on Hoosiers,pirellis and other sticky tires. I'm certain the AP kit is stronger than the oem z06 kit as well.
