Prior Design Takes BMW M3 and M4 Grille Orders

Prior Design has published video and sketches comparing the stock BMW M3 Sedan and M4 Coupe with its own version, which trims back the grille shape, adds a more aggressive front bumper and larger air intakes, and widens the car with alternative fenders and flared wheel arches. The company says the package will lower the stance and make the cars appear broader and more planted.

BMW has defended the large “kidney” grilles on its latest models, arguing they are both a styling cue and functional air intakes for high-performance engines. But the backlash among enthusiasts has created a niche that aftermarket firms can monetize, especially in the sports-sedan and coupe segment where styling loyalty is a major part of the purchase decision.

For investors, the story is a reminder that brand design choices can spill beyond showroom sales into the aftermarket ecosystem, affecting parts suppliers, customization shops and dealers tied to enthusiast demand. It also underscores how quickly consumer pushback can create secondary revenue streams around new launches even when the automaker itself stays committed to the design.

The key test now is whether the early interest turns into repeat volume, especially as BMW expands its design language across more models and prior dissent over the grille continues to fuel both criticism and customization demand.
