Why Choose RW Carbon?

RW Carbon is different in respect to other aftermarket companies in that we are committed to our vision of One Goal - One Focus, Carbon Fiber. Everything we do involves carbon fiber which enables us to provide our customers with high quality carbon fiber items at affordable price-points. Unique to us, we take the time to quality control every item that ships from our warehouse. When you order from many companies online they are shipping a product straight from overseas that has not been quality controlled. If you order one of these parts you could receive a part that is damaged, has scratches in the clearcoat, or overall poor carbon fiber construction. By choosing RW Carbon we make the promise to deliver you a consistent, quality BMW F90 M5 product on time.
