Front and rear rotor specification
Diameter, thickness, friction-face geometry and axle position must be confirmed together. Front and rear systems can differ substantially on the same vehicle.

Technical guide 10
Carbon-Ceramic Rotor Engineering and Size Selection
OWNSILENT generally supplies front rotors from 380–440 mm and rear rotors from 350–410 mm, but range information is not fitment approval. This guide explains the measurements and written specification needed for the exact vehicle.
Hat, hub and offset relationship
Centre bore, bolt pattern, hat depth, offset and mounting hardware position the rotor inside the wheel and caliper envelope.
Confirmed C/SiC reference values
OWNSILENT’s confirmed category references include C/SiC construction, approximate density of 2.0 g/cm³, friction coefficient around 0.45 μ and strength range around 140–165 MPa.
OWNSILENT production stage

Specification and quality-control guidance
- VIN and exact vehicle configuration
- Rotor, hub, caliper and wheel measurements
- Written component and hardware schedule
- Inspection, packing and installation requirements
Frequently asked questions
Is compatibility confirmed by model name alone?+
No. Exact diameter, thickness, offset, hub geometry, caliper clearance, wheel clearance and rear EPB compatibility require verification.
Can components be supplied separately?+
Yes. Rotors, matched pads and approved calipers can be quoted separately when the existing brake configuration is confirmed.
Is professional installation required?+
Yes. A qualified brake technician should complete installation, fluid work, torque procedures, bedding and final inspection.
