Brake upgrade
I just bought a Cobalt SS rear axle off of a guy on the Cobalt SS website. Very reasonable. I am having it sandblasted and installing new hoses, rotors and pads. I also bought new parking brake cables. ABS is the same wiring on the 2005 Cobalt SS and I am reusing my rear hubs.
I also am buying Brembo front rotors, calipers and pads from the same guy and have hoses and spacers on order. I will try to do a "How to" with photos to document it.
I am also installing a Cobalt supercharger over the winter. That should be fun.

Brake update
My "SS" wheels will pose no problem with clearance as SS HHRs came with Brembos as an option. The spacers I bought came from GM and take the place of the dust shield(backing plate) behind the rotors. I almost have all parts together to do the brake update. I will try to remember to document all of it with pictures.

Brake conversion
Well.....I finally did my brake upgrades. Same as Pbatmen. Brembos up front and Cobalt SS rear axle. I tried to remember to take lots of pictures, but probably not as many as I should have.
The front was ridiculously simple. Unbolt the old caliper and set aside with hose attached. slip off rotor and replace with Brembo rotor. Install Brembo caliper with two bolts mounted to old caliper bracket mount position and remove and install brake hose(I used brand new GM ones and they came with the brackets and retainer bolt with copper washers. I did not use the spacers that are shown. They SS steering knuckle and hub and bearing assembly must be slightly larger than the 2LT one. I then gravity bled the system and the job was done. Then I started the rear.

Rear disc brakes
Now for the rear.
I purchased the rear axle from a guy on the Cobalt SS site. He is also the same guy that I purchased the Brembo calipers and rotors from. He may have more available if anyone is interested. Mongorat is his call name. He is very reasonable with pricing and has quite a following. I also bought my supercharger package from him.
