The aftermarket parts don't look much more outrageous than what BMW does with the M4 GTS, and all of these components are carbon fiber.
German tuner Carbonfiber Dynamics announced the M4R project in February 2016, and now nine months later this high-horsepower baby has finally hit the street. It’s a one-off that highlights what the firm offers. True to the company’s name, the coupe uses carbon fiber components from a variety of manufacturers for giving the BMW M4 a racing-inspired look.
The M4R’s carbon-fiber parts include a front bumper and rear wing by 3DDesign. The lightweight parts are surprisingly understated by tuner car standards where being cartoonishly exaggerated is the norm. Varis supplies the side skirts and rear diffuser. Both carbon components look aggressive but don’t overwhelm the vehicle’s svelte design. Finally, MTC Design supplies the hood, which appears to take styling inspiration from that piece on the M4 GTS.
The body features a wrap that takes inspiration from the upcoming M4 GT4 customer racer. The multi-color stripes look perfect on the car.
The most visible exterior mod is 56°Nord’s roof box, and it’s probably also the most polarizing piece. The carrier can apparently hold first up to 186 miles per hour (300 kilometers per hour) and hold 107 gallons (405 liters) of gear, but we suspect many drivers wouldn’t want a black growth on top of their sports coupe.
Carbonfiber Dynamics also turns up the output to 700 horsepower (522 kilowatts) and 634 pound-feet (860 Newton-meters) from a stock 425 hp (317 kW) and 406 lb-ft (551 Nm). Producing that much power from the 3.0-liter turbocharged inline-six requires a lot of work. The company installs TTE 6XX turbochargers running at 33.4 psi (2.3 bar) and adds methanol injection. A new downpipe and carbon-Kevlar intake help bring in the good air and get out the bad. There’s also a 14-disc clutch because the stock unit couldn’t handle the upgrades.
To harness so much additional power, there are 15.4-inch (392 millimeter) Mov’it brakes with six-piston calipers in front and nearly 15-inch (380 mm) stoppers in the rear with four-piston calipers. A Bilstein B16 EDC suspension handles cornering duties.
