The Akrapovic DI-BM/CA/5/G/RS Rear Carbon Fiber Diffuser in High-Gloss finish with the signature Red/White Akrapovic logo is the definitive rear-end statement for the 2018-2020 BMW M5 (F90), M5 Competition, and M5 Edition 35 Years. Hand-laid pre-preg carbon fiber replaces the factory plastic rear diffuser with a component weighing just 1.8 kg, delivering over 60 percent weight savings compared to the factory unit and improving aerodynamic channel geometry for better rear stability at speed. The DI-BM/CA/5/G/RS pairs the polished high-gloss carbon weave with Akrapovic's iconic red and white brand badge, creating an unmistakable signal that this M5 is running genuine Akrapovic hardware. Available as a special order item with typical 5 to 10 business day lead time from Akrapovic's Slovenia facility.

The DI-BM/CA/5/G/RS is the variant with Akrapovic's signature Red/White logo badge integrated into the diffuser panel. The standard gloss version uses a Gray logo. The RS suffix indicates the Red/White badge finish, which is the most visually distinctive and motorsport-aligned badging option for the F90 M5 diffuser.
Does the DI-BM/CA/5/G/RS fit the BMW M5 Competition?Yes. The DI-BM/CA/5/G/RS fits the 2019-2020 BMW M5 Competition (F90) alongside the standard M5 produced from 2018-2020. Both use the same rear bumper architecture and diffuser mounting positions. The M5 Competition package does not alter the rear bumper geometry.
Does this diffuser fit the limited M5 Edition 35 Years?Yes. The 2020 BMW M5 Edition 35 Years is based on the M5 Competition (F90) platform and shares the same rear bumper assembly. The DI-BM/CA/5/G/RS is a direct fit for the Edition 35 Years as well as the standard M5 and M5 Competition.
How much weight does the DI-BM/CA/5/G/RS save over the factory F90 M5 diffuser?The DI-BM/CA/5/G/RS weighs 1.8 kg. The factory injection-molded plastic diffuser typically weighs over 4.5 kg on the F90 platform, making the Akrapovic unit over 60 percent lighter. This mass reduction at the rear of the M5 contributes to improved balance and handling dynamics.
Is the DI-BM/CA/5/G/RS a bolt-on installation on the F90 M5?Yes. The DI-BM/CA/5/G/RS replaces the factory rear diffuser at OEM mounting points with no drilling or cutting required. Professional installation is recommended to ensure consistent panel gap alignment on the F90's precisely fitted rear bumper assembly.
What is the lead time for the DI-BM/CA/5/G/RS as a special order item?Akrapovic typically ships the DI-BM/CA/5/G/RS within 5 to 10 business days from order confirmation. Production is handled at Akrapovic's facility in Slovenia, and international shipping to our warehouse precedes US delivery. We will notify you with tracking information upon shipment.
Is the DI-BM/CA/5/G/RS compatible with non-Akrapovic exhausts on the F90 M5?The DI-BM/CA/5/G/RS is designed with exhaust tip clearances optimized for Akrapovic's F90 M5 exhaust systems. It is physically compatible with the factory exhaust, but the visual and functional integration is designed around Akrapovic's own tip positioning and outlet geometry on the F90 platform.
What does the 24-month warranty cover on the DI-BM/CA/5/G/RS?Akrapovic's 24-month warranty covers defects in materials and workmanship under normal operating conditions, including delamination, structural failure, or finish defects attributable to manufacturing. It does not cover damage from improper installation, impact, or use in competitive motorsport events.
