What do you prefer and why?I have used ebc and hawks I like each of them for different reasons and also discovered that many state they are both semi metallic but the better company and materials preformed noticeably better, the hawk hps stopped me fast enough I could black out from the gs, the ebc had good grip when you really went down on them and ceramics reacted quickly but braked like a standard oem semi metallic.
Crack and monetary compensation
Well, personally, I would just go ahead and get new rotors, especially if you want to get another 30-40,000 out of it. Plus the fact that your basically putting your life and the lives of everyone on the road in jeopardy because you want to get the last few miles out of the rotors. as far as which pad for your application, the ceramic pads are higher end, promote less heat, stop better, since they are a harder material, they would probably wear the rotor out slightly faster than the semi's would. But the semi's would probably wear out sooner than the ceramics, so it is pretty much a 50-50 chance, but for real, you should go ahead and change out the rotor's.
Hawk HPS brake pads are made of Ferro-Carbon. EBC Red is No steel - Ceramic Kevlar. EBC Ultimax website gives no indication of what they're made of. If you carefully weigh all things considered EBC Red is the cleanest, does the least amount of damage to rotors and stopping ability is better than any OEM pad. Presently I'm trying a set of Bendix CQ.3 Ceramic pads with EBC slotted and dimpled rotors. Inside each rotor box there was a warning that said you'd hear an airplane propeller sound while the pads broke in. They sure were right! Apparently the slots cause this. The sound greatly decreased after break in. For the first 500 miles I noticed a lot of brake dust while the pads burnished in. After the first 500 miles the aluminum wheels on the Grand Prix are squeaky clean. Braking power is somewhat better but requires a little more leg to stop. For the hell of it I may switch to the EBC Red's to see if petal pressure is less. I know you can buy Performance Friction at Auto Zone. From past experience on customers cars the Performance Friction pads stop well but they're somewhat dirty. I probably should have stuck to AC-Delco ceramic pads to begin with.
