NRW-Design LLC is a specialized design and manufacturing company focused on creating custom aftermarket parts for BMW vehicles, particularly the M series ranging from the E9X to the latest G8X chassis. Founded by a trio—a pilot (N), an engineer (R), and a master mechanic (W)—the company originated from a shared passion for enhancing BMW performance and aesthetics. Their combined expertise allows them to identify issues and develop innovative solutions, such as the world's first aftermarket aluminum S65 valve cover. Utilizing advanced tools like 5-axis CNC mills and CMM machines, NRW-Design collaborates with local machine shops to bring their designs to fruition. Their mission is to deliver products that meet the high standards of pilots, simplify tasks for master mechanics, and earn the approval of engineers, all while catering to the BMW enthusiast community.
