brembo rotors, genuine or fake? Options

keep in mind that cross drilled and slotted rotors are more abrasive then either or.

cross drilled and slotted-very abrasive
drilled- abrasive
slotted- not so abrasive

this just means that you feel more "friction" on the brake pedal.

Also means you go through pads a helluva lot faster

this has some truths to it since it depends on the pad quality. drilled/slotted rotors are made to disperse heat caused by friction. with less heat on the pads and rotors the longer the pad and rotor life.

now this brings into questions about big brakes. many people say that it is not needed unless you are pushing high HP. this is very true since more "wheel power" will need more stopping power. now big brakes can be very useful for everyday cars too. the life of the brakes will last alot longer since you will not need that many rotor rotations to stop the car.

for example, if it takes 20 rotations with the caliper engaged to the rotor to stop your car going from 45mph-0mph. it would take about 8-10 rotations with a big brake.

now most if not all muti-piece rotors come with heat dispersement fins between the rotors these fins help the travel of heat caused by friction hence longer rotors/pad life

but can they warp faster then normal rotors?

warping all depends on quality and how you "break" the rotor in. aftermarket "performance" rotors will require you to give it a break in period, like a clutch.

this just means you should not slam on the breaks and so forth. there are proper ways to break in rotors.

examples would be:

-"hot-spotting"- this means that you should not leave the caliper engaged even when you are fully stopped (use e-brake).

-"slow"- means give yourself enough time to slow down and let the car roll to a stop.

-"warm up"- on a cold day use the brake at ease until "warmed"

there are a few more that are very common like spraying water on a hot rotor etc...

"hot spotting" and "slow" is to prevent "heat holding" on one area of a new rotor preventing it to warp. "warm up" is to prevent the rotor to from getting hot too fast.
