At RW Carbon, we’ve developed our exclusive RWS Signature Line — a collection of premium carbon fiber parts. These parts are engineered in-house for precise fitment and bold styling. Each design stands out on both the street and the track. You won’t find these carbon fiber parts anywhere else. Today, we’ll highlight some of our most popular RWS pieces to showcase their quality and style.
BMW G8X M3/M4 RWS Carbon Fiber Front Lip
Kicking off our list is the RWS Carbon Fiber Front Lip Spoiler for the 2021+ BMW G80 M3 and G82/G83 M4. This front lip is one of the first custom-designed RWS products created in-house at RW Carbon. It offers a clean, aggressive look with daily drivability in mind. Even if your car is lowered, this lip preserves valuable ground clearance. The design flows seamlessly with the factory body lines of the G8X chassis. Its sharp styling adds performance flair without overdoing it. Each lip is crafted from 2×2 weave genuine carbon fiber for strength and consistency.
BMW F90 M5 RWS Carbon Fiber Rear Diffuser
Next, we’re showcasing the RWS Carbon Fiber Rear Diffuser for the 2018–2023 BMW F90 M5. Unlike generic options, this diffuser is 100% unique to RW Carbon. It also happens to be our most aggressive option available for the F90 M5. We craft it from 100% genuine carbon fiber, making it both lightweight and incredibly strong. Additionally, the diffuser features a three-piece design — a main center section and two side extensions that wrap the rear bumper. This design creates a bold, race-inspired look while preserving daily functionality.
Mercedes C190 GT GTC GTS RWS CF Front Lip Spoiler
Switching gears to Mercedes, the RWS Carbon Fiber Front Lip Spoiler for the C190 GT, GTS, and GTC stands out. We crafted this piece from 100% genuine carbon fiber for a high-end, consistent finish. It pairs seamlessly with other RW or OEM Mercedes carbon fiber parts already installed on your vehicle. To protect drivability, we designed the RWS C190 lip to mount over the factory center splitter. This keeps your ground clearance mostly intact, even after installation. On our in-house GTC with OEM suspension, clearance remains over 6 inches.
Mercedes C190 GT GTC GTS RWS CF Diffuser
Now moving to the rear of the C190, we bring you the RWS Carbon Fiber Diffuser for the 2015–2019 models. You asked, and we delivered a bold, track-inspired design that transforms the rear end. For newer model years, we also offer an updated RWS version. This kit features a three-piece layout — a main center diffuser and two side extensions. Each side piece flows to the wheel well, adding width and depth to your rear bumper. Simply select narrow side pieces for pre-facelift models or wider ones for facelift models.
We also have a similar option for the 2020+. Mercedes C190 GTC RWS Carbon Fiber Diffuser 2020+
BMW F91 F92 F93 M8 RWS Carbon Fiber Front Lip
Last but not least, we finish strong with the RWS Carbon Fiber Front Lip Spoiler for the BMW F91, F92, and F93 M8. This lip features an aggressive one-piece design that flows seamlessly with the front bumper’s natural lines. For even more impact, pair it with other RWS carbon fiber parts to complete the look. The install process is quick and straightforward. You’ll simply secure the lip using self-tapping screws for a clean and secure fit. Every detail of this piece was built for bold styling and daily practicality — just like every product in our RWS line.
