2006 AC Schnitzer ACS4 Roadster Pictures, Specifications, Information

AC Schnitzer's product range for the Z4 M Roadster extends from suspension components and exhaust systems, through a wide range of wheel and tire combinations, to special aerodynamic conversions and last but not least interior accessories.

The response behavior is improved on the Z4 M Roadster 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 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.

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 is a special racing suspension which is currently still in the development phase.

The suspension concept for all ACS4 Roadster 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 tire combinations in 17", 18" and 19", we can now offer the largest wheels for the Z4 M Coupe in 9.0J x 20" with 245/30 R20 tires on the front and 10.0J x 20" with 285/25 R20 tires on the rear axle.

An aerodynamic package has been created which sets even more sporting accents through its styling language and the use of carbon. The package consists of carbon front spoiler elements that optionally can be joined to the front spoiler with chromed aluminum supports. In addition, the new AC Schnitzer chrome front grille gives the vehicles a trendy retro look and at the same time meets the high air flow demand of the 3.2-liter high revving engine.

The vehicle rear is enhanced with a fully integrated carbon rear diffuser. This diffuser is available with two different versions of the special rear skirt edge frame which, depending on which exhaust is fitted, give the "Finishing Touch" to the chromed tailpipes of the Sports Trim or Racing Design and the standard system.

Also the Roadster the product range includes a chrome cover for the roll bars, a wind deflector in clear-glass style and a two-piece rear wing, the triangular parts of which are attached individually to the right and left of the Roadster boot - setting totally new accents.

A particular eyecatcher is the side deflectors with integrated flashers, which as an option can be supplemented with a Chromeline set.

Exclusivity is the trump card in the cockpits of all AC Schnitzer ACS4 Roadster: As well as the carbon interior trim in silver, and matching ergonomically designed AC Schnitzer airbag sports steering wheels, the accents are set above all by the aluminum accessories in silver or black anodized finish. There is also a pedal set with matching foot rest, a handbrake handle and a selector knob for the manual versions. For automatics, there is a carbon selector lever. Last but not least, foot mats with the AC Schnitzer logo, made from high quality velour, complete the range.
