So, like many of the TC owners, my rear rotors are grooved and the pads are down to the plate so I decided to finally change them out. Modern Performance offers an 'OEM' replacement for 08 Cobalts Powerslot Rear OEM Replacement Rotors 08 Cobalt SS - Brakes and the Hawk pads so I went with them. Beyond the fact that it was a pain in the ass to get the piston back in and the rotor bracket off, I have now found out that their rotor DOESN'T EVEN FIT! So as my car is on stands they are closed for the weekend and do not accept voicemails. I PM'd them, so here is to hoping they will see this and OVERNIGHT me the correct rotors. Has anyone else ordered these? I thought they looked small but as they were specifically for rear 08 cobalt ss I figured they would know.

 

Power slot site does not even show/offer any rotors for the SS/TC...

 

I thought the one of the Saab's front brakes were the same as the SS/TC rear so they could be using the rotors for the saab and just say they are for the SS/TC.

 

Modern Performance seems to be pretty sure they are for the 08 tc! How frustrating, no responses to email or anything yet. I'm also having the same problem a lot of you have had getting the passenger rear piston back in. The caliper tool attachment didn't fit so I have been trying to use needle nose pliers to push in as hard as I can and turn clockwise (it is clockwise for both sides, right?) but it just keeps spinning. Oh well, it isn't like I can put it back together anyway so I might as well call it a night.
