Vehicle Fitment and Brake Setup
| Vehicle | Axle | Model years | Required brake setup |
|---|---|---|---|
| Porsche 911 Carrera, all (997) | Rear | with PCCB, uses GT3/Turbo shapes; iron-disc conversion application | |
| Porsche 911 GT3 Cup (997) | Rear | Match the specified vehicle and installed brake system. | |
| Porsche 911 GT3/GT2 (997.1) | Rear | without PCCB | |
| Porsche 911 GT3/GT2 (997.2) | Rear | without PCCB | |
| Porsche 911 GT3/GT2 (997) | Rear | with PCCB; iron-disc conversion application | |
| Porsche 911 Turbo (997) | Rear | excluding PCCB | |
| Porsche 911 Turbo (997) | Rear | with PCCB; iron-disc conversion application |
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. Preserve the GT3/Turbo pad-shape requirements attached to relevant Carrera conversion rows, and verify the rear application independently of the front pads.
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.
