But if you think the looks of the M3 and M4 need even more fiddling with, BMW will happily sell you a set of performance parts that take the models’ looks to a whole new level. There is a slew of visual upgrades available—if you’re comfortable with calling them that. Carbon-fiber front canards, door sills, and mirror caps are just the start, as there’s also a carbon fiber diffuser, swan-neck rear wing, and front splitter. The diffuser is especially baffling, as it complements a titanium exhaust with quad tailpipes arranged in a completely nonsensical—and almost triangular—arrangement.
There are three different wheel options, with sizes ranging from 19- to 21-inches. The 19s are available in gloss black, the 20s in gunmetal gray, and the 21s in either black or bronze. Additional enhancements include performance brake pads and a set of coilovers that lower the car an extra 0.4 inch compared to the normal M3. But the crazy doesn’t stop on the outside, as M3 and M4 buyers can also spec M Performance floor mats and an M Performance Pro steering wheel that’s wrapped in Alcantara. If the carbon fiber exterior bits aren’t enough for you, then BMW will also trim the interior panels in the stuff.
Spec all this extra kit and you’ll no doubt have the most extreme, and fully warrantied, version of the M3 or M4, both of which go on sale in March 2021. Let’s just hope it drives better than it looks.
