Those C6 vette calipers suck. All the track vette guys upgrade from OEM when they get serious. Biggest complaint is flex.

 

Biggest question is do they flex more than our stock calipers though? I'd be surprised if they did. Since they have smaller pistons there is more meat for the caliper body itself. Not only that but they have about 6% less piston area so that would also firm the pedal up a bit. I'm sure the vette guys have plenty of complaints with them but they're also stopping a bigger car with them.

But the biggest point of this is an affordable brake upgrade. Do I want an Alcon/AP/Stoptech brake kit? Hell yea I do, can I justify it, not at all.

 

The C6 Z06 vette weighs less than Evos. Approx 31XXlbs, and way closer to 50/50 f/r than an Evo.

 

 

The C6 Z06 is different than a normal C6. It has an aluminum frame and balsa wood/CF floors. It's something like 150-175lbs lighter than the standard C6. Also dry sump, fixed roof, etc.

I still don't understand how you know those calipers are an upgrade? I've shared some factual real-world experience from people I track with that they are subpar calipers.

 

in my humble opinion it is the discs that need upgrading first not the calipers... they just need more thermal capacity ( as in more mass and heat rejection)

 

 

Okay, so just assumptions based on no real-world feedback. Okay, good luck!

P.S. The C6 Z06 is 12 years old, same as the Evo 9.

 

btw, the C7 Z06/GS calipers are these: and reportedly a much improved version over the C6 calipers

They are massive



The Z51 calipers are much smaller. Both are made by brembo I believe

 

 

What kind of testing are you talking about it? Using them on track or lab testing?

Track testing, yes on the C6 Z06 calipers. The 2nd gen CTSV calipers, no idea as I have yet to see in person anyone to even track one of those 4,300lb boat anchors.

The 3rd gen CTSV use the same calipers as the C7 Z06/GS but different mounting points: https://www.summitracing.com/parts/ado-172-2695

I think you might have a hard time fitting 380mm discs under 18" wheels.

My Trophy's use 355mm and they have been killer with 540whp and 3600lbs.

 

 

*shrug* Do you have videos of your evo calipers flexing?

As another data point, my Evo 10 oem brembo setup was worlds better than my Evo 8 brembo setup. I never got the same flexy feeling with my 10 oem setup but they still weren't up to the task of advanced group and more horsepower. They would start losing braking power very quickly and pull to the side after they had too much heat in them.

Upgraded to Trophys and night and day difference. In fact I am thinking of going down in brake pad compound because they feel like too much now (same ST47 compounds used on both oem brembo and trophy kit)

 

I cannot find a single thing online of people having legitimate problems with the factory C6 Z06 calipers. Once again, this isn't supposed to be a be all end all braking solution, merely an affordable step in the right direction for guys who can't or don't want to fork out $3k+ for a set of brakes.

I don't see such a setup being a step backwards in any measure from stock except for consumable cost which should be on par with anyone who's already running 2 piece rotors.

I appreciate your input and if you have anything else to share I'd love to hear it. Please don't think I'm being dismissive of what you're saying, I just can't find anything that supports what you're saying.

 

For anyone curious, here's what a 380mm disc w/the caddy caliper looks like under an 18" wheel:
