Features:

Stiffest aftermarket caliper available gives a consistent firm pedal
Fully machined and lightweight for track action
Fully forged and extremely stiff for firmer brake pedal feel
Meticulously engineered 2-piece design reduces flex
Patented, removable center bridge further resists yaw(flex)
Carefully selected piston sizes for precise torque output
Specifically engineered and patented AeroVanes for optimum cooling
Patented, billet 7075 aluminum AeroHats for improved airflow
Full-floating mounting hardware to eliminate pad knock-back
Optimized to provide even performance and consistent feedback
Hard-anodized hats are impervious to color change or fading
Stainless steel studs secured with set screws for strength and durability
Fully machined aluminum or steel that is precise and strong
Application specific design for precise and proper fitment
Stainless steel braiding for lower compliance and extra protection
A variety of fittings for hundreds of applications
All necessary brackets and fasteners for easy installation
Better brake modulation
Patented design with directional stand offs between the rotor and mounting bell
Increases airflow by 50%-100% over traditional 2-piece designs
Increased airflow reduces the temperature difference between the inside and outside rotor faces
Results in less distortion and better performance compared to other fully floating designs
Outer pad wear is reduced

Benefits:

Drilled holes create an escape route for debris, dust, gases, and water
Drilling reduces stopping distances in wet weather
Drilled rotors improve the appearance of your wheels and provide reduced rotor weight
Vented type of rotors offers much faster heat dissipation
Multi-piston calipers provide clamping force on both sides of the rotor at the same time and uniformly transfer braking force to the brake pads
Caliper pistons are hollow to save weight
Aluminum caliper body allows for exceptional light weight (up to 40% of weight savings) and ensures superior corrosion resistance
Caliper heat-resistant coating prevent cracking and fading
Fixed calipers create friction from the brake pads on both sides of the rotor at minimum time interval
