The removal of the factory-installed rear seating in a BMW E46 chassis is a modification undertaken for various purposes. This involves taking out the entire rear seat assembly, including the seat cushions, backrests, and any associated hardware. As an example, individuals preparing their E46 for track use often execute this modification.
This alteration offers several potential advantages, primarily a reduction in vehicle weight, which can improve acceleration, braking, and handling. Furthermore, it can provide increased space for carrying equipment, such as racing tires or tools. Historically, such modifications were more common in motorsport but have gained popularity among enthusiasts seeking performance enhancements for street-driven vehicles.
