If you didn’t get your order in for the limited BMW M4 GTS before dealers got a chance to add eye-watering markup, BMW will soon offer a consolation prize. If you have an M3/M4 and a handful of cash, BMW will sell you the performance parts your need to build your own track-ready M4.
Taking inspiration from “motorsports aerodynamics,” the new M Performance fixed wing is ready for the decklid of an F80 M3. It’s composed entirely of carbon fiber, including the side sections and support brackets. BMW only mentions compatibility with the M3, but we’d imagine it wouldn’t be too difficult to mount on the rear of an M4.
Alongside the wing, owners can outfit their M2, M3, and M4 with a new special set of lightweight wheels. According to the automaker, these wheels are designed from the ground up, milled from a “forged blank.” Each wheel comes wrapped in super-sticky Michelin Pilot Sport Cup 2 tires.
A new coilover suspension for the M3 and M4 makes its debut as well. Like most high-dollar coilover sets, these are adjustable, allowing a drop in ride height between 0.2 and 0.8 inch, depending on the owner’s tastes.
BMW shows love to those without “M” cars as well. The new-for-the-North-American-Market M Performance Power and Sound package ups performance on the 340i and 440i. This kit includes upgraded engine management and a new exhaust system, improving power by an impressive 35 hp and 39 lb-ft, though cars equipped with a manual transmission only get a 25 lb-ft increase. Thanks to the extra motivation, automatic 340i and 440is are said to scoot to 60 mph 0.2-second faster than stock.
