Vorsteiner GTS Aluminum Uprights For F8X BMW M3 / M4

The uprights are a complete redesign of the OE M4 GTS wing upright. They are 2 ½ inches taller than the factory upright which allows the wing to sit in cleaner air which increases downforce over the rear of the vehicle. The uprights are manufactured using high grade aluminum and are powder coated anthracite grey. The uprights are a direct replacement utilizing the factory hardware and mounting points.
