BMW ACS4 CSR2, tune and shift pattern

The BMW ACS4 is the CSR2 Prestige Cup Car of Season 110. The 4 yellow star BMW is one of the faster cars in Tier 3.

ACS4 Specifications

The real BMW

The ACS4 from AC Schnitzer is based on the top model in the series, the BMW M40i. The power of the regular Z4 increased to a smooth 400 hp and 600 Nm. To underline the increased power acoustically, there is also a sports rear silencer with exhaust trims in the “Sport Carbon” or “Sport Black” versions.

To ensure that the Z4 brings its horsepower to the road with even greater assurance, AC Schnitzer is also making improvements to the suspension: There is a set of suspension springs or exclusively for the M40i the height-adjustable RS coilover suspension.

As with the technical aspects, AC Schnitzer is of course equally at home with the optical refinements: there are front splitters (a version for cars with M aerodynamics package or a version for cars with Advantage/Sport Line package), a two-piece rear spoiler, and side skirts (only for Z4 with M aerodynamics package). In addition, the portfolio also includes Bonnet Vents for the hood, but in Germany these are only permitted for motorsport use outside the German Road Traffic Licensing Regulations (StVZO). Fo While both measure 10×20 inches for the rear axle, the AC3 for the front axle is 9 inches wide and the AC1 8.5 inches. The tires measure 255/30 R20 and 275/30 R20 in each case.

Last but not least, the AC Schnitzer customer can also individualize the interior of his Z4 with the aid of various aluminium components such as a pedal set, a footrest or even a shift paddle set.


The ACS4 can fit 77 Fusion parts, so far nothing special. The BMW should run 7.726s.
