This was probably answered somewhere and I missed it cause im dumb, but im curious if this setup (c7 caliper)will clear the aftermarket zr1 17x9.5 replicas that oewheels sells without a spacer??
Did you install this setup?
Were Spacers used?
Will this fit on OEM 17" wheels?
Did not buy/install this setup as of yet.
Probably going to do this ATS setup over the 1st gen CTS-V setup...
Reason being:
-C7 325mm rotors will just bolt right up (5th gen Camaro 355mm rotors need hub bore increased)
-4th gen Camaro brake lines bolt right up (no adapters needed)
-Unsprung weight: 20 lb C7 325mm rotors v. 25 lb 5th gen Camaro 355mm rotors
Other comparison can be the C5/C6 brake swap with the bracket and cutting of spindles...
-Same rotor size at 325mm
-Similar cost (if not more for the C5/C6 kit)
-2 piston v. 4 piston caliper
-heat dissipation
-aesthetics ("look")

Any other feedback from users?
Just to put a few points for the 1st gen CTS-V calipers/5th gen Camaro rotors, you are talking about over an inch bigger rotor which will dissipate heat slightly better. No matter which one you go with, I would get new lines and a set of custom lines from Kore3 for the CTS-V's probably isn't much more expensive than a set of stock steel braided replacements for the ATS's. You also shouldn't need an adapter for either, I made a custom adapter for mine because it's an LT1 which has a different hard line, the bubble flare and fitting at the end is the same as LS1 cars, most people bend them around, I just wanted it to look halfway decent but you need to do this even if you swap to LS1 calipers on an LT1 car.
If I knew about the ATS's before I got everything for my setup, I may have gone that route just because I'm a sucker for 17" WS6 Sportlines, however, if you have an 18" wheel and never plan on going smaller you might as well take advantage of that space, just my 2 cents.

That is right, my error... the LS1's don't need an adapter for the hard line connection.
Other than drilling the spindles for the ATS Brembo setup 14mm mounting bolts ... it's easier setup to get going with. No need for the custom lines. No need to get the hub bore increased on rotors. Then if you're in need of rotor or brake line, you can get one from any store... no down time waiting for KORE3 to send you a line or a machine shop getting your rotor hub bore increased.
I do agree with the CTS-V setup with the 355mm rotors will disperse heat better, however... numerous quality and proven racers use the c5/c6 calipers and 325mm rotors on their high horsepower vettes/camaro/protouring cars (similar or more weight than fbody too) with good rotors/pads/fluid/ss lines and they're plenty happy/satisfied with the results.
The ATS Brembo will only complement the results of c5/c6 calipers and the 325mm rotors. Heat should be further pulled from the setup with the larger surface area of the caliper
I installed the ATS brakes on mine in the spring and was a big upgrade. I don't expect to ever autocross so didn't see the real need for the 1in bigger rotors. I did option 1 with different pads/stainless lines and the eibach spacers which included the longer studs. Ill also add the part number for the caliper bolts is Dorman 14006.
So if I wanted to do ATS calipers on my LT1 car, I would first need LS1 spindles, and then everything else listed in here, the ATS calipers, studs, spacers, line adaption, c7 rotors, ATS pads correct? Trying to keep this all straight.
I believe LT1 spindles are different so yes more than likely would need LS1 spindles. Also CTS-v pads are the same as ATS and you can find the CTS pads cheaper.
Yes you'll need an 98-02 spindle. I recommend making an adapter but you can also bend the line around. Check out the link in my sig for the adapters I made (photos are on the bottom of page 4 and top of 6)

You're referring to the 1st gen CTS-V/4 piston caliper pad, correct?
Also CTS-v pads are the same as ATS and you can find the CTS pads cheaper.
If they are in fact the the same pad wouldn't they have the same part # and cross reference over to one another? Or are they the same mounting/backing with a different pad composition?
Also thanks guys for the confirmation on the LS1 spindles etc.
My intent was more it won't be having sustained time periods of high heat and stress like a race car would. Just a short blast now and then. Which of your rotors would you recommend? Again stock size or C5? Hawk HPS pad a good street pad or do you prefer another? I'll probably add the brace too. Keep it simple.
I lost my brakes just playing around on the backroads. Just several 1-2-3 rips early one Sunday morning. Obv had to slow the car way back down each time cuz I was on windy roads...... last time I did it stopped fine, then 15 seconds later driving slowly towards a stop light --- --- no brakes. I wasn't doing anything crazy. Stock brakes are def a weak point, even just playing around on the street.

You would think so. I emailed these people http://www.ctsvbrakeswap.com/ and they confirmed they are the same. Below is the response.
"The 2004-2007 CTS-V pads are the same as the 2013-2015 ATS pads. It's just easier to find aftermarket pads when looking up 2004-2007 CTS-V pads."

Just to add my data point to this, but I'm running the old Prostop / Prospeed (WTF it was called) / Porsche 996tt four piston Brembos on mine and they will clear a 17" ZR-1 wheel no problem.
I've autocrossed it back to back with a similar F-body that had C5 Z06 brakes and there really isn't much of a comparison. Nice thing over Willwoods or other aftermarket options is the fact that parts are easy to come by, the rotors last a long time, and their are a ton of different pad options to choose from.
Now its total overkill for autocross or even daily driving, but I really like them.

How big of an upgrade was it over stock, as in, how much better is your time to come to complete stop do you think? What pads did you go with?
Will option 1 work with Drag Star 92 Series 92-795253DP I have no idea if the ones I have are the 43.50mm offset or the 49mm offset. They are 17x9.5. They clear stock brakes fine.
Looks like the 2000 oem TA wheels 12365483 have specs:
Wheel Diameter: 17 in.
Wheel Width (in): 9 in.
hub bore 70.3mm
Offset +50mm
Backspacing 7 inch
What are the A, B, C dimensions of the c7 jl9 setup on the F-body as referenced here. If someone has these, it would be a good way to determine what all wheels this setup will fit.
It was a very noticeable difference after brembos. I got the "CENTRIC 10510010" from rockauto.
I feel like I tried to mount my stock wheels for giggles and i believe i would have needed a really big spacer. Ill try and mount one again this week and confirm.
