Awesome, happy to see

You could make this all so much easier and run a setup that has cheaper pads too.

LOL. You're right. I forgot. Wasn't trying to be that pushy. But thanks!

I have a spacer question.

The parts list called out for "2X HUBCENTRIC WHEEL SPACERS | 5X4.75 5X120.65 5X120.7 | 70.3 CB | 5MM 3/16" "

Many people have confirmed that 1/2", not 3/16" is required for ZR1 wheels, but I need to know whether or not I need the lip on the spacer. There are 2 versions of the 1/2" spacer on Ebay.
The lip version says "May not fit front hub" in compatibility chart.
The non-lip spacer has no fitment issues.

Could someone please confirm?

What do you mean by lipped spacer? Do you mean hubcentric? A hubcentric spacer would have a "lip" around the center of the spacer to fit in the wheels center-bore to center the wheel and carry most of the cars weight on the hub and not the studs, in that case, you would need a spacer that matches your bolt pattern (5x4.75") AND center-bore (70.3mm). A non-hubcentric spacer doesn't have a "lip" around the center and you just need to make sure bolt pattern is correct.

There's always some debate about whether they're needed with acorn style lugs that technically center the wheel when tightened, I have a buddy who say's "no" but I like the extra piece of mind of having most the cars weight sitting on the hub center rather than the studs, like it does from the factory.

^This. And aside from the safety factor of having the weight on the hub vs. the studs, you can get some vibrations from non-hub centric wheels. If your spacer is not hub-centric and the wheel is then just sitting on the studs, the lug nuts will center the wheels to a degree, but not as closely as the hub will. The tolerances on the hub and center bore are tighter than the tolerances on the lug nuts and the stud positions.

That said, I've used non-hub centric wheels before and not had any issues. I think it all comes down to some luck on how good the lugs actually center your wheel. If I could choose between a hub-centered spacer and one that isn't, I'd definitely choose the hub-centered.

probably can't get quality hub centric spacers until you get to ~19mm or .75". Less than that, the material is too thin to machine the hub centric portion on the spacer. It'll crack off if you find spacers made in specs less than ~19mm or .75". Been there, done that.

It looks like these ATS calipers have gone up in price as well as the rotors. And you can only get them in black with the cadillac logo on them now. Any way to get the red ones that say "brembo" on them like posted in post #53?

handyandy

Post 56 that guy says he painted them himself with high heat paint. Or if you check Rock Auto they have Centric 14262209/10 calipers listed under the ATS that are red in the pictures.

Thanks for clarification. The title of both ebay listings said Hubcentric so that threw me off. I will order the actual hubcentric spacer with lip.

I couldn't find the 172-2586 Driver Caliper in-stock anywhere. Had a SDP parts guy tell me about part number ACDelco 172-2777 as replacement/alternate number.

I found it on amazon and since it was shown in those "Frequent Purchased together" lists with the 172-2587 part number and the caliper bolt kit, i ordered it. It's now not available unfortunately.

I received the 172-2777 caliper yesterday and only took quick look, but it looks like it matches the passenger side. I ordered 172-2586 from Rockauto, but both calipers are black with Cadillac/Brembo logo.

I got takeoff calipers on eBay. Paid under $200 to get both and like new pads, plus no need for the slider pins. Then $35 dollar caliper paint kit, and a $3 brembo sticker from eBay. I scored a single Vette rotor for $33 off amazon but can't find any under $100 now.

The plan is to get this all together this winter and see how big of a spacer/studs I need. Also planning on the founders braided lines.

Oh man, I found a heck of a deal. I got two ATS brembo black calipers for 50 a piece.

I asked a question above but I didn't ask the right one, or the one I meant to ask.

Does anyone have any pictures or experience doing this ATS upgrade with 17x9.5 Torque Thrust 2 wheels? Most if not all of the pictures are of stock SS wheels of various years.

Now I just need to pick out some new rotors and I am set to install them next Monday.

As soon as the rotors come in I’ll post up my ATS 4 Piston Brembo and C5Z06 setup with my 17” Torque Thrust 2’s.

At first I was thinking about getting the 2014+ c7 jl9 base brakes with Acdelco brembo calipers- 722586/87 and rotors #1771155, but those rotors are only 12.64"

Z06 rotors are 13.9' part number 1771126 and CTS-V calipers part number 1722287 and 1722288 look like the better option with more stopping power?

$62.79 per rotor, and $137.99 per caliper.

1. z06 rotors are offset differently, you need to put washers between the caliper and caliper mounting bracket to space it accordingly. Not the safest and secure thing to do
2. z06 rotors aren't exactly large enough for the ctsv caliper. The brake pads hang off the rotor

5th gen camaro rotors are the best way to do ctsv calipers. Proper offset of rotor. Pads/Caliper fit rotor properly. Hub bore needs machined larger though (~$70-100 pair at machine shop).

I did see the need for washers in the sticky post. Good info here, thanks! So you are saying to get 1771050 and bore it out from 67mm to 70.7mm?

yes indeed
