The BMW G80 M3 Carbon Fiber GTX Diffuser+Undertray is an exceptionally aggressive and detailed upgrade for your BMW. Made with real carbon fiber in a 2×2 weave pattern, this diffuser is not only durable but also transforms the rear into a stylish look, pairing perfectly with a trunk spoiler for a complete appearance. The set consists of a 7-piece kit and includes the diffuser, undertray, and hardware for installation. Due to the complexity and size of the diffuser, professional installation is recommended to ensure a perfect fitment. Each piece is thoroughly quality-checked and packaged for safe delivery so you can rest assured you’re getting a part that is brand new.
