Default Just bought a C6Z with AP Racing Brakes, need advice...

I just picked up a 2011 Z06 and it has AP racing brakes on all 4 corners. 6 piston fronts, 4 rear and rotors are 32mm and 28mm with the "j hook" slots in them. Originally, I wanted to keep them on since I intend to road race and autocross this car. But now I'm tossing around the idea of taking them off, cleaning them up and selling them to fund a set of Wilwood Aeros or a set of ZR1 calipers with iron discs. I plan on taking them off to clean them up and turn the rotors anyway, so it's just a matter of putting them back on or selling them. I contacted Essex to get them properly identified and I was told they are CP5260 and CP5200. But he said I would need to do further research to get 100% identification by measuring rotors. Left me pretty confused since their website is difficult to navigate.

My question is, are they worth keeping? Or would I be better off selling them to fund a set of wilwood or ZR1s? Any input is appreciated. I attached a pic of the fronts and rears. Apologies for the bad quality, but the car is still in the shop getting ready.

agreed. as much as i dont care for APs prices.... if you got them for "free" with the car. ANY other brake package would be a down grade.

I had the ZR1 brake package with steel rotors. They were HEAVY, and after 1 track day I could notice a drastic difference in the feel of the car, mostly due to the huge increase in unsprung weight. And i didn’t get the stopping power I was looking after. I have tried C6 z06 brakes will all kinds of pads, stoptech st60 with a vast selection of pads, ZR1 brakes full carbon set up and steel rotors with carbotech pads. The AP kit you have with Colbalt xr1 pads, and finally the AP pro kit with Colbalt xr1 pads. I didn’t notice much of a difference between the two AP kits but they were vastly better than all the others.

Those are world class brakes, keep them. The reason their site is confusing is because AP is constantly pushing the envelope and upgrading parts. The Essex guys will help you determine the exact rotors and pads you need. Their pad is common, and whatever you favorite friction material is should be available. I run g-loc on my AP setup

All good info, thanks guys. I will probably end up keeping them once I figure out exactly what I have.

Keep the APs. Measure the rotor thickness and diameter so Essex can help you choose any rotor ring replacements. Based on their web page it looks like your calipers may have been discontinued but that doesn't mean you can't get service parts, pads or rotor rings.

https://www.apracing.com/product_det...10mm_ctrs.aspx ;

https://www.apracing.com/product_det...available.aspx

I wouldn't bother turning the rotors. I didn't see anything wrong with the two in your pictures. The front rotor is a little abused from what looks like some track duty but if it isn't cracked then keep it but don't try and turn it. May not be all that successful trying to do that with the slots in the surface.

Sounds like I did. I guess i was put off initially because i was unfamiliar with them. Once i get some answers from Essex on pads and possibly replacement rings I'll be set.

There's a reason the championship winning Corvette Racing team uses AP components on their vehicles. Clean them puppies up, flush the fluid, and get some fresh pads then forget about em' for the foreseeable future.

Also NEVER turn or cut the rotors on this type of brake setup. You gain nothing but reducing the heat capability of racing rotors. .

AP's should beat all your other options by far.

You got the hottest most expensive stuff , cool thing is that probably means previous owner didnt cut corners.

The car is pretty much stock. The only thing he added was a Ron Davis radiator, oil and trans coolers, and sway bars. I'm taking it over from there and I dont intend to cut corners. Doing a solid engine build along with coilovers and a few other goodies.

We will help you out over the next few days when we are back in the office (at Essex). Please get the precise part numbers off the calipers (full part number near the brake line inlet port), disc rings (on the outer radius of the disc), disc hats (potentially laser etched) and caliper brackets (possibly laser etched. Without verifying the part numbers, itís very difficult for us to help. AP Racing has a long list of caliper variants that all look identical from the outside.
I believe that is our original endurance kit that has won many races and championships. As noted by others, you arenít going to do much better than that setup!
Donít worry, we will get you sorted.

Also, the discs looks fine. Get us some better pictures of them, and we can determine if they even need replacement. The rear certainly donít look like it!

Please see this article on disc replacement:

Thanks a lot. I'll get some better pictures once the brakes come off this week. Should I send you a message here or contact through the website?

Keep the APís !
Ran them on my C6 GS, nothing better on the market that I am aware of.

Currently tracking a 17Z , M7. I miss the APís every track day.

Don't ever turn the rotors. There should never be a reason to do so. I don't do it anymore on my street cars either. It just cuts down valuable material and heat sink on the rotors.

and most importantly...

Do whatever Jeff at Essex says! He know all about racing brakes.

Agreed!! No need to turn rotors. Haven't done it in years.
