What the replacement includes
The reference package combines the rotor assemblies and matched pads for the confirmed axle. The signed quotation controls the final inclusions, price and logistics.
Front and/or rear C/SiC rotor assemblies, matched to the verified i7 chassis
Matched ceramic-compatible brake-pad set
Vehicle-specific aluminium hats and approved mounting hardware
Configuration for the verified factory caliper
Rotor and pad identification linked to the approved vehicle record
Pre-dispatch surface, dimension and hardware inspection
Installation and controlled bedding guidance
Protected worldwide export packing
Wheel clearance
Check barrel diameter, spoke profile and clearance around the full caliper and rotor assembly.
Factory-caliper compatibility
Confirm the pad shape, caliper part number and complete mounting relationship before release.

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 fibre sheet alignment
The straight-on composition makes the material width, layered construction and operator-controlled alignment easy to inspect.
Prepared carbon strip cutting
This photograph documents continuous material handling at the cutting station without assuming the machine's unverified operating settings.
Layered carbon material feed
The visible roller path shows how broad prepared material is supported and advanced through the production line.
Frequently asked questions
i7 carbon-ceramic replacement, explained
Why does a factory i7 carbon-ceramic rotor need replacing?+
Factory carbon-ceramic friction rings wear down with road use, and can crack from curb strikes or extreme heat cycling. Once worn below the minimum thickness or visibly cracked, replacement is required rather than resurfacing.
Does this cover all i7 trims?+
Rotor diameter, thickness, offset, hat depth and caliper clearance are confirmed against the individual chassis and trim rather than assumed from the model name.
Can the factory calipers be retained?+
Yes, in the applications OWNSILENT supports the replacement 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.
Why choose an aftermarket replacement over an OEM i7 rotor?+
OEM i7 carbon-ceramic components carry high prices and can involve long dealer lead times. OWNSILENT manufactures a VIN-matched aftermarket C/SiC replacement engineered to the same factory caliper geometry, at a lower reference cost confirmed after vehicle verification.
Do carbon-ceramic rotors work the same way on an EV with regenerative braking?+
The friction rotors still handle mechanical braking demand at higher loads and low-speed stops; specification, verification and installation follow the same VIN-matched process regardless of the drivetrain.
Who should install the replacement?+
Installation, torque procedures, brake-fluid checks, bedding and final road-safety inspection must be completed by a qualified technician experienced with performance carbon-ceramic systems.
