Question about CTS-V brakes
 

I was curious if the CTS-V rotors and calipers could bolt on. I see that zzp sells some 14.5' rotors and calipers as well and wondering if you guys had any good experience with them.

Several have installed the ZZP 14.5 inch rotor kits. Get the SS braided flex hoses for best performance , the calipers appear to be Cadillac V 4 piston Brembos

Probably why they are CTS-V. https://en.wikipedia.org/wiki/Cadillac_CTS.
Real overkill, unless you are into serious professional road racing. Made for a car about 800 lbs heavier and 3 times the horse power.

Thanks for the info, correct me if I'm wrong but it seems only the V Brembo calipers are bolt-on.

Yes, you need adapter brackets for the HHR SS for them to fit. ZZP sells that as a complete kit.
