Description

Maxton Design products provide visual enhancement and improve aerodynamics by increasing downforce. They are made of ABS plastic, which is commonly used in OEM parts due to its impact, scratch resistance, and shock absorbance. The product is TUV (TUV Materialgutachten) certified for material quality and treated with a UV protection coating. It is ready for installation, though preparation work may be required for painting the textured version. Professional installation is highly recommended.
