An aftermarket modification designed to enhance a vehicle’s aesthetic and performance. This modification fundamentally alters the car’s original body lines, extending the width of the fenders and quarter panels. An example would be a set of pre-fabricated composite panels, or a custom fabrication, that bolts or adheres to the existing bodywork of a Toyota GR86, substantially increasing its overall width.
The application of such modifications is frequently driven by a desire for a more aggressive visual appearance, and the capability to accommodate wider wheels and tires. Wider wheels and tires improve grip, enhancing handling characteristics on both the street and the track. Historically, these modifications were prevalent in motorsports where maximizing tire contact patch was crucial for achieving competitive lap times, leading to their adoption by enthusiasts seeking a similar aesthetic and performance improvement.
