AP Racing CP9449 Pro 5000R 380x28mm 2NH Rear Conversion Kit – BMW E9X M3
Product Description
The AP Racing CP9449 Pro 5000R 380x28mm 2NH Rear Conversion Kit for BMW E9X M3 enables the fitment of AP Racing CP9449 rear calipers with the genuine BMW 380x28mm 2NH rear brake-disc specification. The conversion uses XC3 rear caliper mounting brackets and E9X-specific HEL rear braided brake lines. The XC3 bracket application is shared across F8X and E9X, with vehicle-specific HEL brake lines.
Choose the kit with a genuine BMW 2NH rear disc pair, or without discs if a compatible 2NH disc pair is already available. Grey anodised or nickel-plated CP9449 calipers can be selected, with optional compatible rear brake pads and caliper pad-retention anti-rattle hardware. The anti-rattle selection does not include disc clips.
Replacement discs: the genuine BMW 380x28mm 2NH rear brake discs are also available separately as a left/right pair. Match the genuine 2NH disc specification before ordering.

They share the XC3 bracket arrangement and CP9449 rear calipers, but the HEL rear brake lines are vehicle-specific.
