This pair of TRE PR-1 carbon side skirts are a direct replacement for the factory M Sport side skirts on G26 M440i and 430i Gran Coupe models with optional M Sport aerodynamics. Adding these pre-preg carbon components gives your 4-series Gran Coupe a more aggressive appearance and a slight aerodynamic improvement.
Only for cars with M Sport aerodynamics.
What is pre-preg carbon? Pre-preg carbon fiber is made from carbon fiber sheets that are pre-impregnated with resin before the molding process, resulting in a very strong and lightweight product with a consistent finish.
Matching components available. Please see below for additional TRE Carbon components to complete the look of your 4-Series Gran Coupe.
