Why RW Carbon?

We know there are many companies out there claiming to have the best carbon fiber exterior additions for your Mercedes. At rwcarbon.com we pride ourselves on taking the time to quality check every piece we ship out. Many other competitors ship you a product that comes straight from overseas - without taking the time to check it. If you order one of these parts you could receive a part that is damaged, has scratches in the clear coat, or possesses overall poor carbon fiber construction. By choosing RW Carbon we make the promise to deliver you a consistent, quality product that is shipped from our Southern California location - the first and every subsequent time you order from us. Additionally, all products shipping from our warehouse are meticulously inspected, and packaged to ensure you receive the best possible Polypropylene Performance Style Diffuser for your BMW F32, F33 or F36.
