@bitter That's a very good point. You read a lot about slotted/vented discs for heat dissipation when in reality you do want the surface area for more friction. Sounds like Stoptech is the way to go (or not in this case). Thanks everyone.

If you're only doing rear then the Stoptech pads are the wrong choice, you'd have too much rear brake bias with them. Try to match to something similar to what the front has already or do all 4 at the same time. It's like putting all seasons on one axle and DOT slicks on the other axle.

Correct. Stock replacement is stock replacement. There's better and worse for sure, those cryo treated rotors really do stand up to harsh pads and heavy use better than standard rotors but standard premium rotors handle it fairly well too. Coated rotors are great for winter driven cars as it staves off rust between the vanes to maintain better thermal performance over the rotors life. I smoked the coating off the front rotors around the disc and between the vanes pretty quick, it's stayed on the hats at least.

 Sometimes the OEM gets it wrong with a particular model and is known for bum rotors. I had three group buys a long time ago where I supplied drilled and slotted rotors back when this option was not available. The guy I used told me some of the differences and mentioned that Brembo rotors are name only and are all the same Chinese stuff produced but its still good quality.  Basically he gave me a choice as he was able to source OEM rotors for our car and his machine would do the drilling. I went with OEM for the group and they never had an issue.    

 At that time I let everyone know that drilled rotors were stupid but the majority  wanted them and unfortunately my complementary set was drilled.  A few years later drilled rotors started popping up all over  EBay.   

Its really hard to know what you are buying these days.

I had StopTech Sports, they were not nearly that dusty. But I'm more of a man than Bitter and don't need brakes 🙂 I ran StopTech Sport front and Centric Posi-Quiet rear, the Posi-Quiet are great pads. Raybestos EHT were amazing on my Corolla.

Dev is right, no real thing as "performance" rotors. Either good or shit. My Powerstop rotors warped within months. Just bad material. The regular Centric Premium rotors, no cryo treatment and no slots, have survived years of autocross, drift, and track abuse. Great products.

Another good point. Doh. I think I can do front brakes. But if I am to do that, I might as well do rear?
