This is the full AC Schnitzer tuning program for the BMW Z4

German tuning powerhouse AC Schnitzer has just launched their full program for the BMW Z4. And at the top of their offering sits the BMW Z4 M40i which now delivers 400 horsepower instead of the standard 340 hp. The BMW tuning specialist from Aachen will soon also be “sharpening” the BMW Z4 20i and 30i models with performance upgrades. A up to 5-year warranty is of course included when the BMW Z4 rolls out of the workshop in Aachen.

Let’s list some of the upgrades. AC Schnitzer sports rear silencers with “Sport Carbon” or “Sport black” tailpipes for the Z4 M40i with 2 tailpipes each in right/left combination (4 pieces) are available for the exhaust. The Z4 20i and 30i can be equipped with tailtrims right/left combination (2 pieces).

AC Schnitzer includes a height-adjustable RS coilover suspension for the BMW Z4 M40i. The company says that the power adjustment in tension and compression as well as a lowering of front and rear by 25 mm each compared to the standard suspension make the racing feeling perfect.

With the AC Schnitzer spring kit, the owners can also lower the Z4 20i and 30i by 25 – 35 mm (front) and 20 – 30 mm (rear) respectively. The Z4 M40i scores with a lowering of 15 – 25 mm (front) and 15 – 25 mm (rear) compared to the standard vehicle.

In the aero department, the AC Schnitzer front splitter brings additional downforce to the front axle. At the same time, the 2-piece rear spoiler increases downforce at the rear axle. The AC Schnitzer Bonnet Vents are only permitted in Germany for actual racing purposes; however, they significantly improve the air situation of the engine. AC Schnitzer side skirts, on the other hand, also provide the intake effect and sporty appearance in road traffic.

The ground contact of the Z4 by AC Schnitzer is produced by wheel sets with a progressive design. AC3 Lightweight Forged Wheels silver/anthracite or anthracite/silver and AC1 light alloy rims BiColor or anthracite bring racing onto the asphalt by using the right tires.

Here 9.0 x 20″ with 255/30 R 20 tires at the front and 10.0J x 20″ with 275/30 R20 tires at the rear are available for the AC3 rims and 8.5J x 20″ with 255/30 R 20 tires at the front and 10.0J x 20″ with 275/30 R20 tires at the rear.

Last but not least, the interior range from AC Schnitzer includes aluminum shift paddle set, aluminum pedals, aluminum footrest and aluminum keyholder meet the highest design demands of driver and front passenger.
