Description

The RW Carbon KMSF32CF-MPRD-428 is a carbon fiber rear diffuser styled after the M Performance package, offering a significant aesthetic upgrade for the 2014-2020 BMW 4 Series models (F32, F33, F36). This component is crafted using authentic 2x2 weave 3K carbon fiber fabric, ensuring both visual appeal and structural integrity. For those without the M Sport package, bumper conversion kits are available as an alternative. The product requires careful selection of the correct exhaust option (e.g., 428i/430i or Quad) to ensure proper fitment. It is important to note that certain products available may be intended for off-road or track use only and may not be legal for public street or highway use in all jurisdictions. Buyers are responsible for ensuring compliance with all applicable laws regarding the installation and use of this product. Please consult local regulations before installation.
