And what will you use for a rotor?
It's been brought up before. I could be done. But it would be expensive and a lot of work.
Use older (early 90s) H body brakes. They'd be alot cheaper for the same thing.
No edit button.....
In fact the CTS uses the same exact rotor as the older H bodies.
I thought those calipers, the bolts screw into the caliper, not the knuckle. Am I wrong?
Also, the H-Body used 5x115 bolt patter, J-body is 5x100.
The H body and the late model CTS have the same factory part number for the rotor, so even if you look around for "CTS" specific rotors, you're going to pay alot more for them. I have Brembo rotors made for the H body on my car, I think I paid about $60 each. I'm not sure about the CTS caliper. I'm going to assume its a floating caliper, just like every other GM caliper (the H body is floating). I looked around for some pics, but only found "representative" pics.
Here is a link to the H body swap How To-

The only real difference would be that your steering arm is on the spindle and not the strut. I would venture to guess that you outer tie rods would work fine with the spindle, even if they needed to be adjusted in or out.
