How OWNSILENT manufactures C/SiC rotors
Inside the carbon-ceramic production process
These production references document OWNSILENT's general carbon-ceramic manufacturing process — carbon-fibre preparation, preform production and precision machining. They are reference production photography and are not specific to this vehicle.
Carbon preform fibre texture
The close-up reveals the visible interlaced texture and layered edge construction without making an unsupported material-state claim.
Large cylindrical preform forms
Their scale and consistent geometry are visible in this wide factory image, though their exact downstream use needs confirmation.
Layered carbon sheet bundle
This production photograph shows the flexible layered construction and manual handling required between visible machine operations.
Frequently asked questions
Defender carbon-ceramic upgrade, explained
Why upgrade a Defender to carbon-ceramic brakes?+
A carbon-ceramic upgrade reduces rotational and unsprung weight, improves fade resistance under sustained heavy use, and resists the corrosion that affects iron rotors over time — useful for a vehicle that carries significant load and towing mass.
Does this fit the 90, 110 and 130 body styles?+
No single dimension covers every body style. Rotor diameter, thickness, offset, hat depth and caliper clearance are confirmed against the verified body style and VIN before production.
Can the factory calipers be retained?+
Yes, in the applications OWNSILENT supports the upgrade rotor is engineered around the verified factory caliper. Its part number, mounting geometry, pad shape and condition must agree with the approved specification before production is confirmed.
Is this a direct bolt-on upgrade?+
The rotor and hardware are engineered to the confirmed factory mounting relationship, but professional installation, torque checks and bedding remain required for a safe conversion.
What information should I send for a quotation?+
Send the VIN, body style and year, wheel size, clear photographs of the current rotors and calipers, and any OEM part numbers visible on the components.
Who should install the upgrade?+
Installation, torque procedures, brake-fluid checks, bedding and final road-safety inspection must be completed by a qualified brake technician.
