California-based Vorsteiner prefers working on the German brands BMW, Mercedes-Benz and Porsche. Having already provided kit for the BMW E92 M3 (coupe) Vorsteiner has now released a new lightweight aero kit for the E90 M3 (sedan).
The package is made up of parts like a carbon-fiber add-on spoiler, a carbon fiber rear diffuser with three integrated fins and a carbon fiber boot lid with a lip spoiler. The latter acts to enhance down force and weighs over 35 percent less than the stock unit which is made of steel.
Thanks to these components the lighter-than-average Vorsteiner M3 sedan should be better placed to exploit BMW's factory 4.0-litre V8 with its 414 bhp (309 kW; 420 PS) and 400Nm of torque.
