there's alot of misinformation here.

first, brake rotors don't warp. it's a big myth. if it's "warped" it's most likely that you didn't bed it in right, or that you were using the wrong type of pads for your driving, leaving deposits on the rotor.

two, rotors don't provide stopping power. please stop saying you got new rotors and you have more stopping power or can stop faster, you don't and you can't. stopping power is provided by the friction material of the brake pad, but how well your car stops is ultimately decided by the tires, the only thing that connects your car to the road. if you have the same tires, your braking distance is most likely the same, unless your old set up was so anemic that it can't even lock up the brakes.

three, stop saying drilled or slotted brakes are for track cars. they're not. the rotor of choice for the average joe user on track is the cheapest blank rotor he can find. track-worthy pads chew through rotors like nothing, no one cares about more expensive, less structurally sound drilled or slotted rotors that provide basically no benefit.

some guy named carroll smith (i think he'd know just a tad bit about cars) on brakes:
