OK so I bought this 6 piston 14.6 inch (370mm) brake upgrade for a great price from shopchevyparts website.
Now I want to find out what the parts numbers are for the rotors and any pads (and track pads) but I can't find any Brembo supplier or any other info despite searching for hours on this site and many others.
Brembo websites don't even list any 370mm versions only 380 and 405
I am hoping that this is not some fake Brembo kit that will kill me when it lets go. Has anybody else had experience with this part number or the new (superseded) 8423-6462 number?
GM does list this as a part number and its supposed to be same as ZL1.
But other sites state that ZL1 has 380mm discs????

Help?

Its not. I ordered mine through them, came with everything. I think they are an excellent track set up as it is. only complaint I have is the dust. eek!
I can't tell by the actual picture, but assuming that's a real 6 pot set up.

The 1LE has the 14.6 rotors and the zl1 has a slightly larger rotor.

10mm difference is less than a half inch (12.7mm) so you figure with a 380mm rotor theres roughly less than a 1/4 inch per radius or less than a half inch on the overall rotor.

If you bought it from shop Chevy parts that it's more than likely legit.

Brembo makes calipers for manufacturers on production cars all the time. However these calipers that we get on the production car that's slightly different and quality then the calipers that you see on their website such as the GT and GT are calipers from what I understand. Those are usually the two piece rotors and red yellow or silver and I think nickel plating. Whereas the production calipers are usually a regular silver aluminum color and then different car companies paint them to their own touch. Such as a lot of brembos you see on Subarus and Nissan are a bronze color. Then you have the GM stuff which is usually red or black. And so on

Giving you some options for brake pads if you check on the road and track forum there's been a few discussions on various types of track pads that people have been using as well as feedback. Also there's been a couple of post on different rotors and rotor rings that people have swapped to.

More or less, it's the same as the SS 1LE front brakes, but with slotted rotors and GMPP branded calipers. It's pad size "1405" in most cross-references. Search for SS 1LE brakes and you'll find a bunch of info that way. They're also the same as the Cadillac ATS-V front brakes. More obscurely, the rotor-rings alone are shared with the C7 Corvette Z06 iron-rotor and gen5 Camaro ZL1, but not their mounting hats, those are different offset.

FYI, it's not the same as the gen6 ZL1 brakes, those are 390mm rotors and use a different casting caliper and a bigger pad. Also, Brembo's website isn't going to list any contract OEM applications, only their own catalog branded offerings.

There are two 6 piston brake setups on the Camaro; the 370x34mm 1LE setup that's sold as an upgrade for the SS, and the 380x36mm ZL1 setup that's shared with the CTS-V.

I think you'll need to get replacement rotors for the 1LE... I haven't seen the LPO rotors sold separately anywhere. The 1LE rotors are blanks.

Great, thanks for the info, I'll try to find something under 1405 cross reference.
If the pads don't fade on a track day, I'll just buy the same ones from dealer.
Found somewhere that a Chevy dealer stated they are 2594-0447. Hopefully that is right.

That should be the right pad #, as it also comes up as the Cadillac ATS-V front pads, which is the same 370mm setup as the SS 1LE.

interested.. can you post the part #s and pricing for the upgrade once you finalize the parts list?

[Gforce8]

will do.
