Brake compatibility: The applications offered here use the specified iron-disc brake arrangements. Where a car was originally equipped with PCCB, the corresponding iron-disc conversion is required. Match the installed caliper, disc and pad shape to the relevant application row before ordering. Retain the stated GT3 front pad-shape and disc-thickness requirements where listed. A related rear-disc upgrade can require a separate rear pad profile.
The brake setup notes identify the complete vehicle configuration. Disc dimensions, caliper spacers or mounting hardware mentioned in an application are not additional items included with these pads or shields.
