Cam-Shaft tweaks BMW M4’s power levels

Article by Christian A., on January 30, 2017

Some customers are difficult to satisfy. There have been instances when customers would opt for a more powerful version of a vehicle. Thus, it would be quite logical to say that one of the primary motives why some customers prefer the BMW M4 over a typical BMW 4 Series Coupe is the power of the car. There is certainly a huge gap in the power levels between the M4 and a regular 4 Series. Customers with a taste for performance are likely to grab the BMW M4.

German tuner Cam-Shaft, however, could also say that there is quite a difference between the potential of its tuned BMW M4 and the power of a regular M4. Cam-Shaft is offering a program that could raise further the power levels of the current M4. As it is, the M4 is powered by a 6.3-liter inline-six engine that is lighter by around 10 kilograms than its predecessors like the V8, although it features similar power levels.

This inline-six is capable of delivering up to 425 hp (431 PS) of max output available between 5,500 rpm and 7,300 rpm, as well as 406 lb.-ft. (550 Nm) of peak torque available between 1,850 rpm and 5,500 rpm. At this level, the BMW could dash from zero to 60 mph in 4.1 seconds via a standard six-speed manual transmission (3.9 seconds with M-DCT transmission).

In this particular BMW M4 tuned by Cam-Shaft, a Level 1 tuning program was implemented. This tweak sent the power levels of the tuned M4 to rise to 513 hp (520 PS) of max output and 531 lb.-ft. (720 Nm) of peak torque.

As to how quick and how fast this tuned BMW M4 could go, Cam-Shaft chose not to provide the details. However, it is pretty reasonable to believe that Cam-Shaft’s tuned M4 could accelerate from zero to 62 mph quicker than the sprint time of 4.1 seconds of a regular BMW M4. Of course, this Level 1 tuning upgrade from Cam-Shaft isn’t free of charge, as a client needs to shell out around €2,199 ($2,344) to avail of this power tweak.

Cam-Shaft is also offering more tuning upgrades for the BMW M4. One of these upgrades is a set of height-adjustable thread springs from KW Automotive that is available for €699 ($745).

These thread springs allow for an individual height adjustment ranging from 5 mm (0.2 inches) to 30 mm (1.18 inches), while making sure that the adaptive adjustment of the absorbers remains active. Clients may also avail of a titanium muffler of the Akrapovic exhaust system for €2,900 ($3,091) or the matte battleship grey exterior finish for €2,000 ($2,132). Cam-Shaft is also offering 21-inch BBS wheels wrapped in 245/30 front tires and 295/25 rear tires.
