Several hard stops in quick succession can send rotor temperatures soaring into the 600, 700 or even 800 degree range. A normal stop from 60 mph can easily raise the temperature of the front rotors 150 to 250 degrees. The underlying scientific principle here is that friction converts the energy of motion into heat - lots of heat! The amount of heat that’s created at the rotors depends on the speed and weight of the vehicle, and how hard the brakes are applied. Friction created by the pads generates heat and brings the vehicle to a stop. IT’S ALL ABOUT HEAT The rotors in a disc brake system provide a friction surface for the disc brake pads to rub against when the brakes are applied. It all depends on the application, how the vehicle is driven, and whether the customer wants a set of performance rotors for show or for go.
It’s a “bling” thing with many buyers, but it’s also a worthwhile performance upgrade. Vehicle owners like the look of a cool set of drilled or slotted rotors mounted behind their aftermarket alloy wheels.
Performance rotors are an excellent upgrade for modified sport compact cars, vintage muscle cars, street rods or hard-working fleet vehicles and even super-sized SUVs.
