The OWNSILENT & Co Carbon‑Ceramic Brake Upgrade Kit for the Jaguar XK120 is a bespoke solution tailored for enthusiasts and restorers who want to modernize the stopping performance of this classic British sports car with contemporary high‑performance braking technology.
The original Jaguar XK120 was produced from 1948 to 1954 and equipped with hydraulic 12‑inch drum brakes on both the front and rear axles — a standard solution for its era that provided adequate performance at the time but pales next to modern braking systems.
Upgrade Package Highlights:
Material: Carbon‑Ceramic Composite
Front Rotor Diameter: Custom disc upgrade (typically 330 mm–380 mm range depending on wheel fitment and caliper choice)
Rear Rotor Diameter: Custom disc upgrade (typically 310 mm–350 mm range)
Designed for aftermarket disc conversion kits (calipers, hubs, and adapters not included)
Superior heat capacity and fade resistance
Dramatically reduced unsprung weight versus steel discs
Modern braking performance with classic aesthetics
Why Upgrade?
Vintage drum brakes, like those on the XK120, can have limited fade resistance and longer stopping distances by modern standards — especially under repeated or spirited use. A carbon‑ceramic disc upgrade improves safety, reduces brake fade, and enhances handling response while allowing enthusiasts to retain the classic styling cues of the XK120.
