M Performance Sill Insert

Description

The M Performance side skirts emphasize the sporty look of the vehicle. Compared to the series, they offer a unique and clear differentiation option due to the finish in high-quality visible carbon. The inserts were developed specifically for the specified vehicle series and are 100% accurate fit. The shaping as well as the design of the side skirts are perfectly adapted to the vehicle geometry and appearance and coordinated with all other M Performance Parts. After various tests, the M Performance side skirts were approved according to the strict BMW Group quality guidelines. All legal requirements are met. A separate TÜV registration and an ABE (General Operating Permit) are not necessary, as the inserts have already been homologated with the complete vehicle or listed in the EC type approval. The sill inserts can only be installed in conjunction with the M aerodynamics package (SA715). In addition, the "Holder light module (MSP)" left and right must be ordered separately, because they are not included. Material information: The sill inserts are made of carbon fiber reinforced plastic (CFRP, carbon) and are sealed with clear lacquer. The material is UV, temperature and water resistant. The carbon perimeters are manufactured by hand. The cutting and draping of the fabric layers, the curing process of the plastic matrix and the milling of the raw parts takes several hours. The subsequent painting process poses a particular challenge. To enhance the unmistakable depth effect of the carbon fabric, the components are painted several times. Each individual coat of paint must be dried and then sanded. After the final coat of paint has been applied, the carbon part is polished to a high gloss (the open-pored carbon versions are an exception). The carbon components are qualified in accordance with the applicable BMW standard. This is the only way to ensure that the high requirements, e.g. with regard to aging and temperature resistance, are met without cracking or paint peeling from the substrate and that yellowing of the matrix is avoided. This high degree of manual work and qualification effort is responsible for the price.
