Vehicle Fitment and Brake Setup
| Vehicle | Axle | Model years | Required brake setup |
|---|---|---|---|
| BMW M2/M3/M4 (G8X) | Front | 2021- | without carbon ceramic |
| BMW M3 / M4 (G8X) | Front | 2021- | with carbon ceramic; iron-disc conversion application |
Brake compatibility: Use with compatible iron discs only. Applications originally equipped with PCCB or other carbon-ceramic brakes require the specified iron-disc conversion; these pads must not be fitted against retained carbon-ceramic discs. Check the fitted front caliper and the exact iron-disc arrangement. The associated G8X rear pad has its own part number and application requirements.
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.
