Vorsteiner have presented their VMS series program for the new BMW 5 Series F10.
The VMS package is suitable for vehicles equipped with the factory M Tech aero package, and it includes a number of carbon fiber components such as an add-on front spoiler, a rear diffuser and a deck lid spoiler.
These elements add to the new F10’s character, and are complemented by a "finely tuned cat back exhaust system", as well as a collection of forged wheels that range from 20 to 21 inches in diameter.
This custom sports exhaust system featuring dual walled tips with adjustable settings, offers a sporty Formula 1 car tone and helps the new 5 Series gain around 12 HP and 2 lb-ft of torque.
The performance gain has been dyno tested but results may vary between each vehicle and individual test results.
