The Akrapovic DI-BM/CA/3/G Rear Carbon Fiber Diffuser in Hi-Gloss finish is engineered for the full F87 BMW M2 family covering the original 2016-2017 M2, the 2018-2021 M2 Competition, and the 2020-2021 M2 CS. Hand-laid pre-preg carbon fiber replaces the factory plastic rear diffuser with a component that weighs 1.8 kg and saves over 2 kg compared to OEM, reducing rear weight and lowering the center of gravity for a noticeably sharper feel at corner exit. The high-gloss 2x2 twill weave finish integrates with the M2's aggressive lines and pairs directly with Akrapovic's slip-on and evolution exhaust systems. Available as a special order item, the DI-BM/CA/3/G reflects Akrapovic's approach to exterior carbon where every component is derived from motorsport material science and applied with the same discipline as its exhaust systems.

Frequently Asked Questions
Does the Akrapovic DI-BM/CA/3/G fit the original 2016-2017 BMW M2 and the M2 Competition?Yes. The DI-BM/CA/3/G covers the full F87 platform: the original BMW M2 produced from 2016-2017 and the M2 Competition produced from 2018-2021. Both variants use compatible rear bumper mounting points for the Akrapovic diffuser.
Does this diffuser also fit the BMW M2 CS?Yes. The DI-BM/CA/3/G fits the 2020-2021 BMW M2 CS (F87N). The M2 CS shares the same rear bumper assembly as the M2 Competition, making this diffuser a direct fit for all F87 platform variants.
What is the difference between the Hi-Gloss (DI-BM/CA/3/G) and the Matte version?The DI-BM/CA/3/G features a high-gloss clear coat over the carbon weave, producing a polished, reflective finish. The matte alternative has a satin surface with a flat sheen. The gloss version is typically preferred on vehicles with painted factory bodywork for a cohesive finish, while matte suits more understated or track-oriented builds.
How much weight does the DI-BM/CA/3/G save over the factory M2 diffuser?The DI-BM/CA/3/G weighs 1.8 kg, saving over 2 kg compared to the factory plastic rear diffuser unit. This weight reduction is concentrated at the rear of the vehicle, contributing to a slight improvement in rear weight distribution and responsiveness through corners.
Is the DI-BM/CA/3/G a bolt-on installation or does it require modification?The DI-BM/CA/3/G is a direct bolt-on replacement using OEM mounting points on the F87 rear bumper assembly. No drilling, cutting, or permanent body modifications are required. Professional installation is recommended to ensure consistent panel gaps and proper torque on mounting hardware.
Why is the DI-BM/CA/3/G listed as a special order item?Due to the high-precision manufacturing process involved in producing autoclave-cured carbon fiber body components, the DI-BM/CA/3/G is produced to order. Typical lead time from Akrapovic is 2 to 4 weeks from order confirmation. This ensures you receive a freshly manufactured, defect-free component rather than aged warehouse stock.
Does the Akrapovic diffuser work with any exhaust or only Akrapovic systems?The DI-BM/CA/3/G is designed with outlet clearances optimized for Akrapovic exhaust systems on the F87 platform. It is functional with the factory exhaust, but the tip positioning and channel geometry are aligned to Akrapovic's slip-on and evolution line exits for the best visual integration. Fitment with third-party exhaust systems will vary by outlet diameter and exit angle.
What warranty does Akrapovic provide on the DI-BM/CA/3/G?Akrapovic provides a 2-year manufacturer warranty against defects in materials and workmanship under normal use conditions. The warranty does not cover damage from improper installation, impact damage, or use in motorsport competition unless specified by Akrapovic.
Installation Instructions
- Verify vehicle is safely supported on a lift before beginning rear bumper work.
- Remove the factory plastic rear diffuser using the appropriate trim removal tools to release all OEM clips and fasteners.
- Test-fit the DI-BM/CA/3/G against the rear bumper assembly before final installation to confirm alignment.
- If an Akrapovic exhaust system is installed, verify exhaust tip clearance through the diffuser openings.
- Install the DI-BM/CA/3/G using the included mounting hardware at OEM mounting points.
- Torque all fasteners to specification per Akrapovic's included instruction sheet.
- Inspect panel gap consistency from all angles and adjust as needed before final torque.
