Features

Note for Australian and European Markets

Clutch lines, master cylinders, brake boosters, and related hydraulic components may differ between Left-Hand Drive (LHD) and Right-Hand Drive (RHD) vehicles.

These variations can include differences in line length, hose routing, mounting points, and bolt spacing, as well as changes in firewall shape, pedal position, or master cylinder orientation.

While some parts may appear visually similar, they are not always directly interchangeable between LHD and RHD configurations.

Please review product images and specifications carefully to confirm suitability for your vehicle, or contact StreetFX support if you are unsure.

Returns are not accepted for special-order products or items installed in incompatible configurations.
