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.

Frequently asked questions
Senna carbon-ceramic replacement, explained
Why does a factory Senna rotor need replacing?+
Factory carbon-ceramic friction rings wear down with track and 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 both the road Senna and the track-only Senna GTR?+
The two share the same replacement approach but different specifications. The VIN or chassis identification confirms which rotor and caliper geometry applies before production.
Can the factory carbon-ceramic 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 Senna rotor?+
As a low-volume hypercar, OEM Senna brake components carry high prices and long lead times when available at all. 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.
What information should I send for a quotation?+
Send the VIN or chassis number, wheel size, clear photographs of the current rotors and calipers, and any OEM part numbers visible on the components.
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 hypercar carbon-ceramic systems.
