Hello, I’m new to this forum, I have a C5 corvette that’s I track and am looking to upgrade my brake calipers to the C6 Z06 calipers, I have a set of calipers however they are missing the threaded inserts that allow them to be bolted up to my C5. Does anyone know where I can purchase reproduction ones or have an alternative mounting solution. The picture below are my calipers and what the inserts look like for reference.
I’m wondering if you might get more responses in the C6 forum? As an interested bystander I’ve done a couple of searches and come up with no references to the threaded inserts — which does not happen often.
If you track the car, throw those in the trash and get real calipers. It doesnt have to be AP. Wilwoods go for just a little more than C6Z stuff and work WAY better. More consistent pedal, less taper, less headaches.

If I had the 5K plus to purchase new calipers I wouldn’t really be bothering in this thread. Im well aware a new big brake kit would be better performance. I’m 22 working on a tight budget trying to chase my dreams. Everything on this car is used off market lol. The only reason I’m even upgrading to begin with is my c5 calipers seized at Sebring in October.
your saying the 6 piston front and 4 piston rears off a c6 z06 are a just looks upgrade over the 2 piston front and 1 piston rear off the c5?
Yeah, the number of pistons doesnt matter. Its the same total piston volume. The C6 Z caliper have their own issues and are more difficult to work on. C6Z calipers still flex and twist and make the pedal mushy. They are a weak body design. They are bulky and retain heat. The pads still taper. The 1 piece pads help a little but still not worth the change. I would have rather put that $650 into a Wilwood kit or something else the car needed, but that is a pretty decent price compared to what they go for.
For reference, when I put Wilwood Aero 6 on my car it didnt change the peak G's under braking at all from the stock C5 calipers. Same exact numbers. I was consistently braking around 1.4-1.6G with each setup. But the pedal feel was way better, pads lasted longer, and my confidence in the pedal was there each time. I still use the stock rear C5 calipers in my setup.

lol yes maybe I should have clarified more I’m not looking to be able to brake later or have more peak brake pressure I’m aware that just a swap of calipers isn’t going to change that alone. My issues is heat, after 2 days at Sebring my oem calipers failed and after inspection from some of the TT guys there they think it’s because the calipers are getting too hot. My budget solution was to get the c6 Z06 calipers, from what I understand they will disperse heat better than the oem ones and the larger rotors as well should help, they bolt directly up to the OEM mounting location. I was previously running Motul 660, I’ll be switching to Castrol SRF and adding better air vents to both the front and rear brakes. I’ll also be upgrading my master cylinder and brake booster to the post 2009 corvette model to try and help my peddle dropping mid corner. I don’t use abs or traction control but I’ve heard that the seals in the master cylinder wear and can cause peddle drop so hopefully the new master should help that.
I’m not an expert by any means but I have experience racing formula cars so I don’t believe the issue to be my brake references or braking technique.
Are the C6 calipers not even less bad? They are a non floating caliper, I'd think there'd be some sort of advantage there. I will say going from C5 calipers to a fixed Stoptech with 2 piece rotor was an absolute game changer for my 4th gen Camaro. Same peak braking force, but finally a consistent pedal that I could trust every single time. Ironically I still have my PB on the C5 brakes, but that doesn't mean I'd ever think about going back to them.

I spoke to a few of the guys at the track and they all seemed to be of the opinion that overall it was an upgrade over the oem c5 calipers. Not perfect but between the two options the c6 Z06 were better…
