Complete widebody conversion for the 2014–2020 BMW M4 (F82/F83). Vehicle-specific ABS panels engineered from 3D scans, adding up to 3.94 in (100 mm) per side while preserving the M4's unmistakable silhouette.

The SHIROKAI BMW M4 F82 Widebody Kit 2014–2020 is engineered for the F82/F83 BMW M4 platform, giving the car more width, sharper side lines, and a stronger stance while keeping the factory M4 silhouette recognizable.

This is not just an fender flares kit. Each SHIROKAI BMW M4 widebody kit is CNC-cut from platform-specific 3D scan data for cleaner fitment, better proportions, and less fabrication drama during installation. Made from premium automotive ABS plastic, it is built for stance, street, show, and track-inspired M4 builds.

BMW M4 F82 Widebody Kit by SHIROKAI

After the huge success of our Mini kit, we expanded into more European cars — and the Bimmer was next to go live. We wanted to balance aggressiveness and accuracy while keeping the original body shape recognizable, adding streamline, width, and a lower visual profile. If you’re searching for a BMW M4 widebody for sale, this setup delivers the signature SHIROKAI look with practical fitment details — material quality and fitment matter as much as looks when you compare BMW M4 widebody price options.

Every SHIROKAI build starts with this photo.

Open the box. Lay every panel around the car. Take a step back. That photo is the first memory of your build.

Overall the kit has been one of the best fitting kits I've worked with.
