2-Piece Floating Brake Rotors
What Makes 2-Piece Rotors Superior?
Ghost Rotors' 2-piece floating rotor design represents the pinnacle of brake rotor technology. By separating the rotor ring from the aluminum hat, we've created a brake system that delivers unmatched performance, reduced weight, and exceptional thermal management.
- Separate aluminum hat - CNC-machined aerospace-grade 6061-T6 aluminum
- High-carbon iron rotor ring - Premium G3000 grade cast iron
- Floating attachment system - Allows independent thermal expansion
- Up to 15 pounds lighter per vehicle than OEM
Superior Thermal Management
The aluminum hat acts as a massive heat sink, drawing heat away from the friction ring:
- Lower operating temperatures: Aluminum dissipates heat 3x faster than cast iron
- Reduced brake fade: Maintains consistent pedal feel under hard use
- Extended component life: Lower temperatures reduce pad and rotor wear
- Better airflow: Gap between hat and ring allows air circulation
Eliminates Thermal Stress
The floating design accommodates thermal expansion without transferring stress:
- No warping: Friction ring expands freely without distortion
- No cracking: No stress concentration around mounting holes
- No pulsation: Maintains flat, true surface even after heat cycling
- Longer lifespan: Rotors last significantly longer than one-piece designs
Advanced Rotor Features
Ghost Rotors 2-piece rotors combined with double drilled holes and diamond slotted patterns create maximum cooling:
- Aluminum hat draws heat from friction ring
- Drilled holes allow air to flow through rotor
- Slots remove hot gases and debris
- GEOMET® coating for corrosion protection
Perfect for High-Performance Applications
2-piece rotors are ideal for vehicles that demand maximum braking performance:
- Track & Racing: Fade-free performance under extreme conditions
- High-Performance Street: Daily driving with track-day capability
- Towing & Hauling: Consistent braking under heavy loads
- Mountain Driving: No fade during long descents
