2007 AC Schnitzer ACS4 Z4 M Roadster

Now that the Z4 Roadster has undergone a facelift and at the same time the M-variant, the Z4 M Roadster, was launched, the model range has been completed with a new Z4 Coupé and MCoupé. Not only BMW but also we at AC Schnitzer are thrilled with the range of new Z4 vehicles, and present our interpretations: the AC Schnitzer ACS4 Roadster and the AC Schnitzer ACS4 Coupé.

The product range extends from suspension components and exhaust systems, through a wide range of wheel and tyre combinations, to special aerodynamic conversions and last but not least interior accessories.

The aerodynamic range has been designed so that - with few exceptions - the special accessories for the ACS4 Roadster will also fit the ACS4 Coupé, and similarly the conversions for the ACS4 M Roadster are compatible with the ACS4 M Coupé.

To improve the driving dynamics, for the Z4 M Roadster and M Coupé we offer a modified rear axle ratio of 3.91 : 1 (standard 3.62 : 1). The AC Schnitzer rear axle ratio guarantees greatly improved acceleration.

The response behaviour is improved on all Z4 models thanks to the AC Schnitzer sports rear silencers. Made completely of special steel with chromed Racing tailpipe, they also provide a more sonorous note than the standard system. For purely visual enhancement, on the Z4 Roadster and Coupé chromed tailpipe trims are available in the same design.


For the M-versions of the Z4 that are fitted with a twin sports silencer as standard, as well as the Twin Racing system there is a further option of Sports Trim Design. This design is reserved exclusively for M-vehicles and was previously seen on both the M5 and M6.

Faster and more precise gear shifts promote the adrenalin rush and perceptibly improve acceleration in a car. So the AC Schnitzer Short Shift has been adapted for the BMW Z4 3.0i, 3.0si and M-versions with manual transmission.

For safe control at all times of the driving performance of the new BMW Z4 models, except M-variants, a special high performance brake system has been developed for the front. The internally vented and slotted brake discs measure 334 mm in diameter and are 32 mm thick. The special brake calipers are fitted with two 42 mm pistons. Naturally the standard ABS system is retained in full.

Extensive tests on race tracks and public roads have resulted in the development of a complete suspension concept consisting of AC Schnitzer sports suspension, special antiroll bar kit and strut braces. The total concept, the components of which can also be fitted individually, achieves sports handling with the same high standard of driving comfort.

In addition, exclusive to the M Roadster and M Coupé is a special racing suspension which is currently still in the development phase.

The suspension concept for all ACS4 Roadster and Coupé models naturally also includes the AC Schnitzer Type IV, Type III and Type II alloy and racing rims in one-piece and multipiece construction. As well as a wealth of wheel and tyre combinations in 17", 18" and 19", we can now offer the largest wheels for the Z4 Roadster and Coupé in 9.0J x 20" with tyres 245/30 R 20.

The M Roadster and M Coupé are even fitted with 9.0J x 20" and 245/30 R 20 on the front and 10.0J x 20" with 285/25 R 20 on the rear. For tyres, we recommend high performance tyres from Continental and Michelin.

The bodywork of the AC Schnitzer ACS4 models reveals the high technical standards that we apply to our products. So for the Z4 Roadster and Coupé and for the M Roadster and M Coupé there are two tailored outfits that fulfil these attributes.

The front part of the Z4 Roadster and Coupé is enhanced by the strikingly designed front spoiler attached to the standard front skirt. This also ensures better downforce. The rear is rounded off by the new AC Schnitzer rear skirt which not only harmoniously integrates the sports rear silencer into the rear but at the same time gives the vehicle a more imposing appearance.
