For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Cadillac ATS Brembo Front Brake Swap

Post by superman22x on Mon Jul 17, 2017 6:09 pm

I recently have been working on a Z06 Caliper swap, and thought another option might be worthwhile.
I am thinking of using the Cadillac ATS Brembo brakes. They are a good size 4 piston brembo caliper, and can be had for $125/each from Rockauto. Or junkyards have them in the $25-50 range each. I would like to fit these to stock 298mm turbo/87+NA rotors. This would keep the swap super cheap and simple. The stock rotor size for the ATS is 321 front, 315 rear. These calipers will only get cheaper as well, as it is the same caliper used on the V6 Camaro, ATS, and CTS. In addition, I believe, the same mounting point for a 300mm rotor with V6 ATS Brembos would work with V8 Camaro Brembos on a 330mm Cayenne rotor.
Alternatively, a different design could mount the ATS brembos with the 330 Cayenne Rotors, V8 Camaro Brembos with 350mm rotors, and I believe could be used with the CTS-V calipers and 380mm cayenne rotors...
Looking for some thoughts from the community. If there is some interest, I believe I can have these made shortly after my Z06 adapters are finished.

What is the center to center bolt measurement on those ATS calps? If they could also be adapted to the 928 spindles.... Win
Cardone showing 42mm pistons and that's ideal for stock MC.
The sheeple on Renny would be on board with these adapters for sure

The mounts are 128mm apart. Mounted on a 90.5mm radius when used with the 321mm rotors. The rears have the same mounts, but with 315mm rotors. I believe the 3mm radius is changed in the caliper it self.
