I am very interested in how this turns out. I'd do it tomorrow if it works.


My stock brakes are shot and I've been holding off for this very reason.

GM sells this as an upgrade for Z51 and base cars; it will work. The only issue is wheel clearance. Since I ordered CCW wheels , I'm OK, but if I understand it correctly, you need 4mm spacers for it to clear Z51 wheels.

X25

Well, it did not take long; I received all the parts!



The caliper is 9.3 lbs empty, and 14 lbs with pads + hardware (dry).




As expected, it only too 1.5 weeks for the parts to arrive (even though it said 1-2 months delay).

I'm not sure this is totally correct. The way the info reads is that you need a minimum 4mm space between the caliper and wheel when installed to guarantee sufficient margin to prevent contact under all conditions. That may translate to a 4mm spacer.... or not. Could be more or less of a spacer needed. You'd have to mount it all up and measure. I wish someone with z51 wheels would have a close look at this and report.

I'm actually yet to receive my car, but I suppose I could test it out when I get it.

By the way, what do you guys think about the brake lines? I ordered both the OEM brake lines and StopTech SS brake lines; I'm not sure which ones I should install to be honest. The OEM lines look very nicely built, and the OEM type rubber usually is more sturdy against rock hits, etc. (but rubber lines are more likely to cause catastrophe when they fail, compared to small leaking of SS lines when those lines fail)

I used the Goodridge SS lines from Tire Rack on my 4th genCamaro and they worked great. Not sure there was all that much improvement over stock but the pedal did feel a little firmer. The stock Z51 brakes feel fine to me as is, though.

On the left, StopTech ST60 pad, on the right, Z06/ZL1/CTS-V pad on the right, C7 rear pad at the bottom.

Just ordered the rear Z06 brakes, too:
Rotor: 20981824 x 2 = $300.25 x 2 = $600.50
Calipers (black): , = $219.31 x 2 = $438.62
Total: $1039.12

The 2-piece rear rotors look amazing!

So you do not have a C7 to put these on yet?


For $1000 I might just gamble and buy it with some spacers.

X25

You're rubbing on my wound : (

I am yet to receive my car, but I ended up ordering everything I think I'd need. The price is indeed very attractive. When the total price for a big brake kit is same as a set of aftermarket rotors, you ought to give it a try : )

Will this work on a C5? This looks very tempting. I've been contemplating going to 6 piston Wilwoods with 14.x" rotors but this looks pretty amazing.

X25

Cars that come with Brembo calipers seem to have same caliper mounts (though sometimes different rotor offsets). That said, Neither C5, nor C6 came with Brembo brakes at any trim, and I'd highly doubt if these brakes would work; sorry! I don't know for a fact, though.

Someone ought to investigate, this seems like a great option. 2 piece rotors and superior modern calipers... straight from GM

Any update on this, especially whether a spacer is needed? I'm getting really sick of brake fade at track events, and if someone is getting fade with Castrol SRF (I use ATE 200), then I hope the Z06 brakes are a valid solution. Brake fade is the Achilles Heel of the Z51, and I'm growing very tired of it (10+ track days on my 2015). I added the Z06 grill to aid in air flow to the brake cooling vents, and that didn't seem to help at NCM this weekend. Current setup is DBA T3 Rotors with Carbotech XP12s up front, 10s in the rear on stock rotors (no real wear on the rear pads or rotors - the fronts take all the abuse).

As for pads, will the stock Z06 pads be comparable to a dedicated track pad? If not, is anyone having better performance than Carbotechs are giving?

I'd just love to be able to 100% rely on the brakes all session (30 min) without worrying when the pedal will go to the floor. My friend's 458 Speciale with Carbon Ceramics can seemingly brake hard all day without nary a hint of fade. I'm sure the Z07's brakes do the same, but I'm not up for that kind of investment. There's got to be a steel solution at this Z06 brake price point!

X25

Yep, I've tried the brakes with stock wheels.

For the fronts, I first used 5mm spacers, and it barely cleared. I would recommend at least 7mm spacer up front.

Rear Z06 brakes

The rear Z06 brakes are cleared by OEM Z51 wheels with no spacer, but barely! I think it would need at least a 2mm spacer for ample/safe space between the caliper and spokes.

Z06 brakes are a major upgrade. The front rotors are unfortunately not curve-vaned, but they should still be OK since they're massive in comparison. You can also get DBA 5000 T3 replacement rings from KNSBrakes at about $300/rotor, which are directional, and should substantially improve cooling.

What tire are you on? The stock ZO6 pads do not compare to the Carbotech pad as far as wear ,bite , modulation and so fourth.

Jedi-Jurist

For now, stock MP SS's, but considering changing wheel sizes for dedicated track tires as well. Will the Z06 brakes clear an 18" wheel up front? If not, how does the car do with 19s square? I think someone who was racing the C7 was running 19 sq with success, but I lost track of that thread.

X25

Stock 18" won't clear Z06 front brakes (but my CCW wheels do). Stock Z51 19"/20" wheels clear the brakes with 6+mm spacer up front and 2+mm spacer at the rear.

By the way, personally, Carbotach pads never really worked for me. They are very soft, and don't give me the confidence for late braking. Their harder compound version are better, but even then, ST43s and ST47s I've used last 3x more, and they are similarly priced. Obviously, your mileage may vary.

Jedi-Jurist

Thanks for the info, have you tracked the setup yet? How did they hold up? I like the CT's street pad, which is compatible with their track pads. Does ST have a similar setup?

X25

I stripped my steering wheel bolt, so had to cancel this weekend's track day, waiting on a $4 bolt. Next one is on 7/25 : )

In their catalogue, ST31 is listed as for street use. You can take a look at their compound comparison charts at the bottom of this page.

I have used ST43s before on my '13 C6 Z06, and they were great! I have used ST47/45s on my C7 Z51 only at the street, and so far they feel pretty good. They do have good bite when cold, too, and are not as corrossive as Hawk pads, so I usually just leave them on for the entire track season (summer and parts of spring/fall).

I will hopefully get to extensively test the brakes on 25th. The open track format will allow me to have 1 hour sessions, so if there is a heat build-up that the system can't shed, I'll know : )
