Euro-Floating Rotors

European ///M's come with cool two-piece floating rotors. The rotors differ from the US rotors because the "rotor hat" is made of lightweight aluminum and connects to the braking surface with several small pins. Every other aspect of the rotor is the same (size, mounting holes, etc.). The benefits are three fold: One, the rotors are less susceptible to warping because the rotor hat and braking surface can expand at different rates allowing some play in the system before warping occurs. Two, the rotor hats won't conduct as much heat to the wheel bearings. And Three, the rotors are a little lighter in a crucial place to loose weight... they are an unsprung mass and a rotational mass. Hardcore track junkies know that unsprung mass is a key element in determining the suspension's ability to adhere to the road as it changes topography and rotational masses are critical in that they are 3-10 times more of a factor in braking and acceleration then a the car's body weight. Saving a pound in the rotor is like saving 3-5lbs from the body of the car.
