The phrase
"iron rotors" refers to the rotating part of a machine or vehicle made of iron, which is a strong and durable metal.
Full definition
Large
ventilated iron rotors absorb heat, and one is located within each of the supercharged model's standard 20 - inch alloy wheels.
The LS 500 F Sport RWD gets 20 - inch alloy wheels with 245 / 45RF20s in front and 275 / 40RF20s rear; six - piston monoblock calipers grab the 400 mm
front iron rotors while four pistons grab each 359 mm rear disc; the optional Performance Package on gas - powered F Sport models add variable gear ratio steering, active rear steering and active stabilizer bar.
Braking is accomplished by discs all around; the V - 6 sports 12.6 - inch cast -
iron rotors in front, with 12.4 - inch aluminum units in the rear.
And when the car dove downhill into the Turn 2 hairpin, we stepped deep into the brake pedal and the racing - style, two -
piece iron rotors did their stuff, thanks to six - piston Brembo calipers on 15.5 - inch rotors in front and four - piston fixed calipers on 12.6 - inch rotors in the rear.
Both front and rear consist of two - piece,
cross-drilled iron rotors with aluminum hats (the hats are the center pieces that connect to the hub).
These rotors thermally separate the central hub (constructed of aluminum) and the vented and cross drilled cast
iron rotor disk.
Large cross-drilled grey cast
iron rotors measuring 380 mm front and rear are standard, while the Porsche Ceramic Composite Brake system with 410 mm rotors at the front and 390 mm rotors at the rear can be ordered as an option.

Through the 125 - to -194-mph high - speed zone, the light weight (3461 pounds on manual - transmission models, down 33 pounds), the lifesaving brakes (there's no need to upgrade from the standard cross-drilled and vented cast -
iron rotors), and the riveting aerodynamics (serious downforce in the rear, modest lift in the front) effectively smooth out and control the flight path.
Corvette Z06 Brake Kits (
Iron Rotors) for Stingray with Z51 * Designed for Stingray models equipped with the Z51 package, they feature the Z06's standard, two - piece and slotted iron rotors — measuring 14.6 - in.
The S upgrades to ceramic - composite brakes — 50 percent lighter than cast -
iron rotors — with yellow calipers.
This time Brembo casts
the iron rotor directly onto a special aluminum alloy hub with numerous spokes.
Available in the Dynamic plus package, front carbon - ceramic disc brakes are lighter, saving up to 8.82 lbs compared to traditional cast -
iron rotors, and offer increased resistance to fade.
Available in the Dynamic plus package, front carbon - ceramic disc brakes are lighter, offering up to 8.82 lbs saved in contrast to traditional cast -
iron rotors.
And while large in size, they are low in mass, saving approximately 11 pounds (5 kg) per corner over comparably sized cast
iron rotors.

If neodymium is relatively inexpensive, PM rotors may make economic sense; if not, one can use
an iron rotor and a field coil.
