The ATS is 5x115. Ls1 hubs take 5x4.75/5x120 c7 is 5x120

the c7 rotor hub bore, offset, and bolt pattern is correct for the ls1 hubs. When I fit them up I was happy the caliper and rotor offset matched without any spacing for the caliper. They look like they belong on there.

Looks like DBA makes a slotted 4000 series rotor for the C7 Base that could be used as an upgrade.

yes they accept fbody lines. I forget the banjo thread size.

While it would be much more expensive, I would love to see someone dish out for the c7 z51 calipers. They are identical calipers but the casting on the ears is longer to accept the 345mm rotor. I will measure again, but I am confident the z51 brakes will be direct bolt on as well with 17'' wheels. This would still be cheaper than most aftermarket big brake options.

Then I may grab a single rotor and caliper and try them out with an Eibach 15mm spacer with the BS Street Lites. Might fit, might not. But it would be cool if it did.

I'd probably run them with Ferodo DS2500s...

Cadillac ats 4 piston brembos are identical to the base JL9 calipers on the c7 corvette and can be found cheap new stock. I would love to see someone do the c7 z51 calipers with the 345mm rotor and believe this will fit. They are the same 4 piston brembos with longer mounting ears and could be found used for a decent price.

- For my stock zr1s I am running the arp studs with a 12mm/.5'' spacer and there is plenty of clearance.
I can only assume with the clearance that any 17'' wheel with .5'' more backspacing than zr1s will fit right up. These brakes perform great on the street and road course. They are matching parts - calipers and rotors. No need for washers or hub boring.
very nice!

i assume the stock zr1s will not fit this brake set-up without a spacer?

Some interesting info! Might be worth a look. Do you happen to have the part numbers on the calipers?

If you search the older part numbers JakeFusion posted they're a lot cheaper.

Definitely book marking this thread for later use of part numbers.

Rotors - I went with acdelco c7 rotors. They are oem brembo. The ats rotors will not work. From what I remember the hub bore and more importantly bolt pattern is different.
Ok so we are looking at:
acdelco brembo calipers 1722586/87 - $128 each
c7 rotors 1771155 - $55 each
14mmx1.5x40mm bolts - $5 dorman 14006 gm pn for them is 15016308
Bosche blue be1001 pads $25
Acdelco caliper hardware kit - 18K1971X - $19
ARP 2.5'' studs and 1/2'' spacers
Dorman parts H620066/67.

Then just bore hub mounting holes to 14mm/9/16'' to accept the new calipers.

Will Race Star 92 Drag Star 17x9.5 (6.875in) backspacing on a 2000 camaro work with this setup without having to grind the calipers or are 1/2'' 5x4.75 spacers needed?

The rotors are like $55 from what I saw...

And I'd put much better pads on there. The Ferodo DS2500s is what I would do... and they are $250 for the set. But they are the best street pads out there (which you can use for HPDE events and not fade to hell). We just can't get them for the PBR 2-Piston calipers as Ferodo doesn't make them for that caliper.

Being as this is a great budget 4 piston brembo setup with oem parts... I would stay away from $250 brake pads. Remember our cars weigh about the same as the new stingray, a car owners love taking to HPDE events without any issues of brake fade. $250 dollars for street pads is mental.... wait until you find out how often you have to change pads on a tracked car. Spend a little more on the acdelco/brembo rotors and get a decent set of pads...

I'm saying that Stoptech has a lot of various rotor options. None are to the level of the DBA 4000's. And on the basic end I've personally liked the Best rotors a lot, but folks like the name Stoptech better, and the black hats. For street it doesn't really matter. But for track use it does.

Rotors on Rock Auto that I saw were Delcos and they were $55 a piece and in stock. Theyre the blank rotors like pictured in post #12 on Boosted53F's car. I believe the 1771171 is a larger diameter rotor and won't work for this upgrade.

You are right. 5.7stroker grabbed that part number. The brembo rotors I am using - #1771155*** The larger 345mm rotor 5.7stroker listed would work if you went with a set of z51 calipers.
