Got to have an LT5 and BIG Brembo brakes.

Tried to send a message but box is full again. Can you go into some detail on how the C6 ZR1 caliper and ZL1 rotor worked together? I know on IG you said a custom rotor hat but i'd like to hear as much detail as possible. I'm wanting to eventually get out of the wilwoods on my car and move to something more OEM quality.

There is a bit of a story. I love the Carbon Ceramic brake set up on the C6 ZR1, but they require a lot of brake cooling to work correctly. I did that on Hellfire and they work great. I did not do that on Jackass and they would get too hot.

To get better brake performance with out all the extra complexity of big cooling ducts you can add Thermal Mass (Iron Rotors).

I wanted to swap the Carbon Rotors on Jackass to Iron. The new CTS-V and ZL1 use a 390 mm iron rotor that is the same thickness as a 393 mm Carbon Ceramic rotor. The 3 mm delta is taken up by the pad.

OK easy I’ll swap the 390 mm iron rotors on Jackass. Issue is the offset on the CTS-V and ZL1 hat is different. No problem I have friends with CNC machining centers that make gun parts. I was informed the tolerances on my brake hats are tighter then gun parts.

So I got some ZL1 Rotors and added my custom hats.

To recap. Stock C6 ZR1 calipers, 390 mm Gen 6 ZL1 Rotors and custom hats. The ZR1 calipers use the same brake pad shape for Carbon Ceramic and Iron Rotors.

I had all this stuff laying around so I’m going to try it.

It will be easier to buy a Brembo kit.

I also noticed the Grand Prix. Looks like the one Holley was building a couple of years ago.

fwiw I noticed the 1st gen Firebird to the left...

I went with KORE3 brakes on my car for the OEM reasons stated above.

Any chance of a production run of modified ZL1 rotor hats in the future should these prove your theory Mark?

Very great info on the brakes your a world of info. What Diff are you going to run in this car? I just had one go with 700 miles on it and I know you beat on your cars. Ford 9 from DSE and a eaton its DONE! I didn't even get to work on it. Found broken parts and a washer in the bottom. Cant wait to see this LT5 push this car around the track .

Ford 9 inch gears are my nemesis. I have lost track of how many sets I have failed in my life. I do not think it is the fault of the diff assemblers. My data shows it is poor gear manufacturing. I attempt to use real Ford gears and they seem to be the quietest and most durable. Occasionally you will get a good aftermarket set of gears. I found out that most gear suppliers set up there tooling / gear grinding and let it run until it is way out of tolerance. So if you get an "Early" set they may be good and if you get one of the last ones they maybe bad.

US Gear is going to make some "Stealth Gear" that are suppose to be more to OE tolerances. My buddy has a set to test on how quite they using some "real" measuring equipment. (An actual engineering test).

I hope they are good and stay good. Our community needs a better solution than digging though junk yards to find usable old Ford gears to get a quite gear set.
