RE: OEM Brake material
That's a tough question.
You'll first have to decide if you want silent, dustless brakes, or high performance brakes. Because you can't have both.
Ceramic is quiet and dustless, but they lack in stopping power.
Carbon or semi-metallic are the best performers, but they are dusty, and they will squeak if they are really high performance.
I opted for performance. Carbon-metallic is reportedly the best performing material that will not squeak when cold. A set of front pads costs $50 at Autozone.
I have also had EBC Greenstuff (kevlar) pads. They are slightly better performing than what I've got now, but they cost $100 and despite what they say, still create a lot of dust.
I have never had ceramic pads.
