The modification refers to a BMW E46 sedan that has been altered to feature extended wheel arches. This aesthetic and functional change allows for the fitment of wider wheels and tires, enhancing the vehicle’s stance and potentially improving its handling capabilities. An example would be an E46 sedan with significantly flared fenders, accommodating wider track width than the factory configuration.
This type of modification is often pursued for its visual appeal, creating a more aggressive and customized appearance. Beyond aesthetics, the wider track achieved through this enhancement can improve cornering stability and grip, particularly in performance-oriented applications such as track racing or spirited driving. The practice has roots in motorsports, where maximizing tire contact patch is crucial for optimal performance.
