I think I got a good deal on drivewire.com. PBR REAL 4 bolt rotors and PBR quiet, dustless pads for both fron sides including a coupon I found for 5% off and free shipping came to $125.93. Not QUITE as good as brembo, but the best they had are drilled rotors with about 9 holes in them for 4 or 5 bolt wheels. I prefer the RIGHT fit so I went with PBR. I'll report back when I have them installed.Hawk pads are everywhere...I can't remember where I have seen Brembo blank rotors available for the Cobalt though...carpartswholesale.com might have them. Can't remember where else though...not sure if I've seen any 4-lug in anything other than blanks.
