Sweet - I could not find the proper pad shape (AP CP5060 caliper) in my searches for Cobalt pads.

0Anthony @ LGMotorsports

I'm going to confirm with Jeff and Andie both but I believe I know which one it is.

Here is some brake pad **** from cobalt. Gotta love how thick these 25mm monsters are up front compared to stock z06 rear pads.

From our website regarding brake pad shapes:

Pad Shape for Six Piston Front AP Racing CP5060 Caliper


The pad shape our CP5060 caliper uses was created by AP Racing many years ago, and is used by a wide range of racing calipers today. It’s available in just about every popular racing compound on the market. That means you’ll never end up in a pinch without pads. The available pad compounds that Essex sells for the CP5060 caliper can be found below. Please keep in mind that there are many other compounds available on the market from other manufacturers. The list below is only what Essex sells. When purchasing this brake system, you have the option of buying one set of any of the pads in the list below at 50% off of the retail price. Underneath each manufacturer below, the pad compounds are listed from most aggressive to least aggressive.

CL Brakes= RC8, RC6, RC6E, RC5+

Ferodo Racing= DSUNO, DS1.11, DS3000, DS2500

Hawk Performance= DTC-70, DTC-60, HPS, Performance Ceramic

Note on using brake pads different from those listed above

Again, please keep in mind that the above is not an exhaustive list, and that there are many other pad compounds available in this shape from other manufacturers. Please note however, that the pad shape we use in our caliper is available in a variety of radial depths (heights), and that Essex recommends the 54mm radial depth version. Another common radial depth in this pad shape is 51mm (StopTech for example, uses this size in their ST-60 six piston caliper). The 51mm depth pads will fit into our caliper, but you will be leaving an unswept 'ring' around the disc near the attachment points to the hat (the pad will not hang as low in the caliper). Leaving a portion of the disc face unswept can create a temperature differential across the face of the disc, and doing so could lead to premature disc cracking.

Here's a drawing of the pad:

Hi Guys,

We've had a number of customers ask us recently if they can run an OEM-Style C6 Z06 disc with our front Endurance six piston kit, since they have the same overall dimensions as the AP Racing discs in our kit (355x32mm). The answer is yes, it will work with a slight modification. That said, we always recommend using our complete system with the AP Racing discs that are included. These parts are designed to work together for superior results. We do recognize however, that some customers may have been running OEM-style discs for a number of years and could have a considerable quantity of spares on hand, might need a spare disc in a pinch at the track, etc. Please note however, OEM replacement discs from various manufacturers tend to vary in size and tolerance, and Essex cannot guarantee the fitment or performance of any disc other than the ones included with our kit. The data below is for informational purposes only!

The offsets on the discs in our system are slightly different than stock, so to fit an OEM-style disc with our calipers, you would need to install a very small shim (0.032" or 0.81mm) between the caliper bracket and the upright, moving the caliper out towards the wheel spokes. One shim is used around each caliper bracket mounting bolt for a total of 4 on the front axle. You can see one of the shims circled red in the images below. The shim goes between the bracket and the suspension upright, and this does not require the use of a longer bolt. Adding the shims centers the OEM-style disc within the cailper. These shims can be found here. If you decide to do this, please note that wheel fitment will change, and allow for an extra 1 mm of clearance when using our wheel fitment template).

Also note that we will not sell our big brake kits without discs, so please don't ask! Again, we recommend our complete system including the AP Racing discs for maximum performance and reliability.

Below is the OEM style disc installed without a shim. You can see that the disc is not completely centered in the caliper:


In this pic you can see a shim installed, circled in red.


With the small shim installed, the disc is centered in the caliper.


Here is the disc installed:

Hi Guys...I don't think I've posted any pics of our four wheel kit installed yet...so here it is!

Our kit shaves 34 lbs. of unsprung weight off of a C6 Z06!!! That's 18 lbs. off the front of the car, and 16 lbs. off the rear.

Essex Designed AP Racing Competition Big Brake Kit for C7 Stingray

While the C7 Base and Z51 brakes are more advanced vs. the C5 & C6, there is still a lot of room for improvement. Based on everything we’ve learned during development, we believe our system offers our customers the following advantages over the front OEM C7 Stingray brake systems:

The large 380 Alcon and AP brake is really very good.
However, strain With hard I'm a little disappointed with the brake disc.
Since we switched to Brembo discs ... live much longer.
Also, all GT3 team of Callaway have changed from Alcon on Brembo

Below is the first in-car footage of our front Competition six piston kit in action.

This was Oli T taking the first podium on this kit out at Inde Motorsports Park in Arizona a few weeks ago. This was an SCCA Majors race, in the GT2 class.

Skip to the tail end to see him reel in a 911. He even bumps the Porsche for a little drama...oops. Congrats Oli!

Olitho

Ha! Yes, Jeff I did reel them both in very well. It is evident that the vaunted Porsche braking had absolutely zero advantage on my AP caliper and rotor equipped Corvette. In fact, if there is one area where my car was performing the best against the Porsche it was under braking. The best part of the whole video is the last lap at minute 36 or so. Shortly after that mark, three turns before the end, I bump him lightly.

Spencer, the driver, was hopping mad. Watch the closing seconds of the video and you will se his door open twice before he even stops. He could not wait to come and yell at me. I cut that part out of the video as it is choice. The stewards stepped in to calm him down. I thought his reaction was extreme as it was called in by the corner workers as a racing incident and I did not spin him and there was no change of position.

soon!

Well, you did a good job.

My front endurance kit should be here tomorrow or monday!

Sweet! Thanks for the purchase.

All Current Essex/AP Racing BBK owners please read below

We recently sent out a survey to those who bought their Sprint or Endurance kit directly from Essex. Now we're looking for those who bought their kit from a different shop. I have a survey that I'd like you to complete. It will help us continually improve our products and offer more of what our customers want. In exchange for filling out the survey we will offer you a very nice gift at no charge...and yes, it's something you will want and can use. Please shoot me an email and I'll send you the survey.

Hi Guys...We're doing a $500 off Tax Day sale on our AP Racing Factory BBK's. Again, this is only on the Factory BBK's for the C5 and C6, which are the road & track product. The discount does not apply to our Competition Kits.

Front C5 Black
Front C5 Red
Front C6 Black
Front C6 Red

These have a 362mm disc and are about as big as you can cram behind an OEM C6 Z06 18" wheel. They come with everything you need...even brake fluid and pads. Despite being huge, they don't have any weight penalty on a C5 or base C6, and shave nearly 10 lbs. off the front end of a C6 Z06! Get 'em while they're hot.
