Another vote for Centrics. I even had no probs with the OEM grade C-Teks. Paid $13 something per rotor w/free ship on Amazon. I could see going w/the Premiums for the e-coating.
Whatever you go with, make sure you put the lug nuts back on in a star pattern and torque to spec. I've had no probs following this.
I've noticed that the C-TEKs generally measure between 0.002" and 0.003" of lateral runout once installed onto the car, despite using a high-rpm drill and a scotchbrite disc to thoroughly clean the hub flange. This is simply too much runout for most modern cars, which tend to call for 0.002" max. The excessive runout eventually leads to disc thickness variation, which results in a pedal pulsation complaint.
Centric Premium 120-series or High-Carbon 125 series are the way to go.
Good point but I must have just got lucky because the revised max lateral runout spec from GM on my vehicle is .0015" and I notice no pulsation w/the C-Teks. I'm actually pretty demanding when it comes to driveability. Ask any mechanic that works on my cars when I don't.
Also, I didn't see anyone mention that you definitely might want to inspect/service your slide pins. At a minimum clean and re-lube them with high-temp ceramic grease like that purple Permatex stuff. Mine were so bad I just replaced them with all new HW.
