You can always count on the BMW M4 to be a favorite among aftermarket tuners, and as long as the car is around, you can expect more tuning companies to dive into their bag of tricks to build new programs for the sports coupe. Some, like Carbonfiber Dynamics, have even built multiple programs for the M4. I mentioned CarbonFiber Dynamics because it’s got an updated version of the M4R program for the high-performance coupe, one that builds from its own previous work back in February 2016 with plenty of new additions, including a more powerful net output of 700 horsepower and 634 pound-feet of torque.

The extra power is the highlight of this new kit, but it’s far from the only one. It also received some new body wraps in the iconic colors of BMW’s own M Division. There’s also a new aerodynamic kit that’s in tune with the M4’s performance characteristics. Oh, and let’s not forget about the upgrades on the car’s exhaust, suspension, and brakes. They’re far from sexy additions to the M4, but with the massive engine upgrade anchoring the whole program, these auxiliary modifications serve important purposes themselves.

You can tell by how CarbonFiber Dynamics approached this program that the tuner wasn’t just content on offering something different from what it developed earlier this year. Nope. This one is better in a lot of ways and the results speak for themselves.

Take it what it’s worth, but just so you know, this new program for Carbonfiber Dynamics is arguably one of the most comprehensive aftermarket takes we’ve seen for the BMW M4 since the coupe arrived in 2014 to warm our hearts and break our piggy banks.

Exterior

With so many distinct modifications, it’s hard to tell which among these upgrades count as the highlight of the program. So let’s just go through them all. Arguably the most striking is the GT4-style body wrap from Revowrap, which, as mentioned above, also takes inspiration from the red-blue-purple color scheme of BMW’s M division. Give credit to Carbonfiber Dynamics here for sticking to its identity because its last program for the M4 also featured some visual wraps of its own, albeit using random black patterns whereas this new wrapping from Revowrap fits into the M4’s identity and lineage.

Outside of the cosmetic modifications, CarbonFiber Dynamics also has an aerodynamic kit for the M4 that’s made up of an MTC Design hood, a new front bumper and rear wing from 3DDesign, and side skirts from Varis. Once more, there are similarities with its previous kit for the M4, but there are also different approaches, most notably with the naked carbon fiber hood on the previous program. Likewise, the front fenders and mirrors on this program appear to be stock, whereas those in the old tuning kit were replaced with carbon fiber versions.

It goes without saying that the upgrades on this new program are far more colorful than the last one. It’s also more all-encompassing, thanks in large part to the presence of the 56°NORD carbon roof box that Carbonfiber Dynamics claims has been tested at speeds of up to 186 mph. Overall, the look and feel of the BMW M4 dressed in the tuner’s new exterior upgrades give the sports coupe the kind of sporting character you expect it to have.

Interior

It should come as no surprise that Carbonfiber Dynamics’ new M4R program for the BMW M4 is bare with interior upgrades. Even the old MR4 kit didn’t have any modifications in the cabin to speak of. Actually, you can run down the list of notable tuners that have presented programs for the M4 in recent months – G-Power, B&B Automobiltechnik, and McChip, among others – and none of them offered anything that even remotely resembles something in the way of upgrades to the sports coupe’s cabin.

Note: Standard M4 interior shown here.

The good news is that even if Carbonfiber Dynamics didn’t do anything to spice up the M4’s interior, there are ways around it for customers, most notably going to BMW itself to get the job done. After all, that’s what BMW Individual is for, right? Over the years, BMW has given us various examples of how it can personalise the interior of the M4. One example is the BMW M4 Pyrite Brown Edition, which M4 DT a Sonoma Beige Merino fine-grain leather for the seats and the door panels, to go with the Individual Sycamore Red-Brown fine wood trim. Black leather surfaces were also included in that offering and featured contrasting stitching while the seats were also fitted with illuminated M inserts.

On the opposite end of that spectrum is the M Champion Edition. The modifications to the interior aren’t so much about adding more luxury to it as it is completely changing its function and purpose. Sure, the cabin was still dressed in Leather Merino and Alcantara, but for the most part, it received a GTS-style makeover, which included M Carbon bucket seats, an M Sports steering wheel, and a white rollover bar that replaced the rear seats entirely.

The point here is that BMW Individual has your interior upgrade needs since Carbonfiber Dynamics’ M4R program does not have you covered in that respect.

Drivetrain

Give Carbonfiber Dynamics this much credit: it knows how to tune engines. That much was evident back in February when it was able to squeeze out 600 horsepower and 610 pound-feet of torque out of the M4’s 3.0-liter turbocharged inline-six engine. The German tuner accomplished that by not only upgrading the M4’s turbochargers, but by also adding in a new air intake, a high-flow air filter, a methanol injection kit, and a tuning module from Burger Motorsport JB4 that came with eight different ECU maps. Impressive, right?

Well, the tuner somehow outdid itself this time around by actually putting in a pair of TTE 6XX turbochargers running 2.3 bar of boost pressure and combining that with the same methanol injection kit and Burger Motorsport JB4 tuning module from the previous program. The result is an impressive 700 horsepower and 634 pound-feet of torque, numbers that should allow the M4 to sprint from 0 to 62 mph in about three seconds to go with a top speed that could peak north of 200 mph. At the very least, this Carbonfiber Dynamics-tuned M4 can do 0-to-124 mph in just 5.9 seconds.

Compare to that to some of the other programs for the BMW M4 and you’ll realize just how impressive this tuning program is. Take G-Power, for instance. Just like Carbonfiber Dynamics, G-Power has presented multiple iterations of its tuning kit for the BMW M4, including the highlight item in those programs: the Bi-Tronik 2 V3 tuning module. Not only does this module feature bespoke upgrades designed to give BMW’s twin-turbo 3.0-liter straight-six engine around 600 horsepower to play with, it’s also complemented by a larger yet lighter turbine and compressor wheels into the turbochargers. Another tuner, B&B Automobiltechnik, actually offered a multi-stage tuning kit that included modifications to the turbochargers, as well as a higher-flow intake tract, larger exhaust downpipes, more efficient charge air cooler, and an ECU remap with revised fuel, spark and boost parameters. All together, B&B only managed to get 580 horsepower and 553 pound-feet of torque out of the Stage 3 kit.

All of this is to say that as far as benchmarks go, Carbonfiber Dynamics’ updated M4R tuning kit for the BMW M4 ranks right up there as one of the best kits, if not one of the most powerful, in the business today.

Check out the table below to see how Carbonfiber Dynamics’ program compares with other programs from other aftermarket tuners.

Suspension and Brakes

With so much extra power under that MTC Design hood, it’s no wonder that Carbonfiber Dynamics saw fit to upgrade the M4’s suspension with Bilstein’s new B16 EDC suspension system while also adding a Mov’it-signed braking system with 6-piston calipers and 15.4-inch discs at the front and 4-piston calipers and 15-inch mm discs at the rear. All that power has to be handled carefully and the modifications to the car’s suspension and brake systems help ensure that.

To be fair, other tuners have also offered similar suspension and brake upgrades, including G-Power and B&B Automobiltechnik. G-Power’s work on the M4’s suspension revolved around it’s own GM4-RS coil-over suspension kit whereas B&B offered a threaded height adjustable sport suspension kit that lowers the sports coupe’s ride height from 0.19 to 0.98 inches. The latter also has a more aggressive upgrade in the form of a set of sports springs that drops the car’s ride height even further, or by as much as 1.18 inches at the front and 0.78 inches at the back.

Pricing

Tuners don't always reveal the prices for their programs and it's no different with Carbonfiber Dynamics. As per usual, the best way to go about it is to contact the tuner directly since most of these upgrades are actually sourced from other aftermarket companies.

Competition

BMW M4 by B&B Automobiltechnik

I did mention earlier that B&B Automobiltechnik has a multi-stage engine kit available for the BMW M4. So let’s dive right into all of them. All three stages come with the same set of modifications that were detailed above. The only difference is that each stage is tuned to produce a specific amount of power. I already detailed the output for the Stage 3 kit (580 horsepower and 553 pound-feet of torque) so it’s only fair that I do the same for the Stage 1 kit (490 horsepower) and the Stage 2 kit (540 horsepower).

BMW M4 by McChip

This is arguably the least impressive among the BMW M4 programs that we’ve talked about. That’s not necessarily McChip’s fault because the tuner has been responsible for some pretty incredible upgrades. But the numbers say what they say and in this case, McChip’s kit for the M4 only nets an output of 517 horsepower and 405 pound-feet of torque. It’s not much compared to what Carbonfiber Dynamics has on the docket, but it’s still good enough to get some noticeable improvement on the M4’s performance numbers.

Conclusion

Maybe it’s the way the M4 is dressed or maybe it’s the gaudy numbers, but whatever they are, it’s hard to deny Carbonfiber Dynamics’ updated M4R program for the BMW M4 it’s proper recognition. Simply put, it’s as impressive a kit as we’ve seen made for the M4 since the car burst into the scene in 2014. That’s not high praise considering that we’ve already seen plenty of tuners take a stab at the sports coupe, to varying degrees of success.
