Show original supplier description

The Kies Motorsports "M3 Style" Rear Bumper Conversion is engineered to give your E90 BMW 3 Series sedan the aggressive look of the E90 M3. This conversion kit is designed as a direct bolt-on for any E90 chassis 3 Series, requiring no unnecessary modifications for installation. However, it is important to note that this is not an OEM replacement bumper and will NOT fit the OEM E90 M3. Additionally, aftermarket lips and diffusers designed for the actual M3 may or may not fit this conversion bumper. Installation may require transferring some parts from your original OEM bumper. The product is available in non-PDC (Parking Distance Controller) versions, meaning you will need to drill holes and transplant your PDC brackets if your vehicle is equipped with sensors. Exhaust compatibility varies: a 328i typically has a single-sided twin pipe exhaust, while a 335i can accommodate aftermarket tips for a quad exhaust look. Please consult your local body shop for proper fitment and painting, and ensure you make the correct selection for your vehicle's exhaust setup during purchase. This product is intended for off-road or competition use only and is not legal for installation or use on public highways in jurisdictions that restrict such modifications. Customers are responsible for ensuring compliance with all applicable federal, state, and local emissions laws.
