Triton Motorsports' floating brake discs bring true two-piece rotor construction to the F85 X5M and F86 X6M — a floating aluminum bell paired with a separate high-carbon iron alloy disc ring, built to handle the demands of these high-performance SUVs without the drawbacks of a fixed OEM rotor.
The floating design allows the disc ring to expand and contract independently of the bell as temperatures rise, reducing warping and internal stress that a one-piece rotor can't dissipate as effectively. Combined with directional venting for improved airflow, that means more consistent heat management under hard, repeated braking — the kind these vehicles' weight and power routinely demand.
Key Features:
- Two-Piece Floating Construction — separate bell and disc ring reduce thermal stress and warping versus a fixed one-piece rotor
- Improved Ventilation — directional vane design supports more consistent heat dissipation under sustained braking
- Reduced Unsprung Weight — the aluminum bell trims mass at each corner compared to a fixed steel rotor, supporting sharper handling response
- Built for Repeated Hard Use — engineered for durability across both street and track conditions
Front 395x36mm
Rear 385x24mm
Fitment: F85/86 BMW X5M, X6M
Please note that in this vehicle fitment, the rear disc brake rotors are one piece due to the thickness. If you desire two piece construction, please reach out to us via email before placing the order.
Ring Material: G3500 High Carbon Iron Alloy
Hat Material: Billet Aluminum
Warranty: 1y/36000 mi (whichever comes first) against manufacturer defects.
Note: Several other machining patterns are available. Please contact us via email at info@tritonmotorsportsusa.com to discuss.
The price is for a set of front and rear discs. Pads are not included.
Turn around time ~35 days
**For replacement rotor rings, please contact us via email.
**Noise reduction/anti vibration shims are highly recommended.
#Hardware pictured is optimized for weight. If you desire Bobbin style hardware for more space, please specify via email.
##Weight reduction dependent on OE construction and may not be as significant in all applications.
