Hawk HUS503 Quiet Slot Rotor
Hawk Performance Quiet Slot Brake Rotors
METALLURGY: Quiet
Slot rotors are cast from a proprietary formulation of premium
alloys producing a superior performance street product.
- Noise dampening steel formulation.
- Long grain carbon iron for maximum thermal stability.
- Molybdenum additive for high temperature strength and thermal
crack resistance.
- Unique alloy blend provides exceptional rotor life and
durability.
DESIGN: Quiet Slot
rotors combines the look, feel and durability of a true performance
rotor with the fitment and convenience of OE design.
- Performance design ? Direct OE
replacement.
- Unidirectional vanes eliminate the need for left and right side
rotors.
- Optimal rotor vane and wall thickness improves structural
strength, noise dampening and heat capacity.
- OE style vane design combined with
increased heat capacity dramatically improves brake pad and rotor
life.
QUIET SLOTS: Hawk Performance Quiet Slot rotors
feature a unique slot design specifically engineered to improve
your car?s braking performance and driver comfort.
- Increases initial bite.
- Improves wet weather brake performance.
- Effectively removes gas and wear debris.
- When the brakes are not engaged, the Quiet Slot rotor vane and
surface slot design effectively cuts through the surrounding air
flow virtually eliminating the ?whirling? noise typically
encountered with cross drilled or heavily slotted rotors.
- Visual wear indicator. Rotors should be replaced when slots are
worn down and no longer visible.
- Optimizes overall brake performance.
QUALITY: All Quiet
Slot rotors are meticulously checked for proper balance, thickness,
flatness and runout. All rotors are manufactured in ISO certified facilities.
SURFACE FINISH:
- Swirl ground surface for improved brake pad bed-in and ?green?
out of the box performance.
- Specific RMS finish accelerates the
creation of a proper transfer film when run with Hawk Performance?
brand brake pads.
- All rotors are finished with a GEOMET? coating that protects
both the internal and external surfaces from rust and
corrosion.
WHAT IS GEOMET?
GEOMET is a proprietary water-based
coating dispersion containing metal oxides, metallic zinc and
aluminum flakes. The zinc and aluminum platelets align in multiple
layers forming a metallic silver-gray coating. Applied as a liquid,
the coating becomes totally inorganic after curing at 575-600? F
(300-315?C).
