Pairs well with
RW Carbon now has our very own take on a rear diffuser for the BMW G30 LCI 5-Series. This will fit all 2021+ G30 LCI models with the M Sport package, which includes the 530i 530e 540i, and M550i. This RWS Diffuser is made using genuine carbon fiber and will perfectly match any other G30 RW Carbon Fiber parts and/or accessories you already have on your car. This diffuser does require the removal of the rear bumper for installation. Due to this we highly recommend that you have either us at RW Carbon install it or another professional shop. Elevate your G30 to the next level in a matter of a couple of hours with a new RWS Diffuser. Please contact us today if you have any further questions!
Installation
RW Carbon requests that you must get this RWS carbon fiber diffuser installed by a professional. The diffuser does require the entire rear bumper to be removed and screws inserted into the diffuser tabs. For further information feel free to email us at info@rwcarbon.com.

About Us
What started as a group of BMW enthusiasts tired of overpriced parts and limited options is now a brand trusted by thousands of owners nationwide.
We designed our own product lines from the ground up and built the production infrastructure to make them happen. No middlemen, no compromises. Just the parts we actually wanted on our own builds.
Now we operate out of Oceanside, California, engineering valved exhaust systems, carbon fiber, forged wheels, front-mount intakes, and more. Everything is designed in-house, tested on real platforms, and stocked locally for fast shipping.
This is just the beginning.
