Carbon fiber body parts are starting to become a dime-a-dozen, but this has caused a reduction in part quality. Vorsteiner takes great care to ensure every carbon fiber component they produce is of the highest quality, putting every piece through an independent inspection process to look for any potential imperfections before they leave the facility. In addition, the high gloss clear coating applied to their carbon fiber parts is a UV ray inhibiting coating that won't discolor or peel after only a few years of sun exposure. Looking to make your G8x M3 or M4 more unique? Then this may be the perfect option for you! Vorsteiner's VRS Aero Rear Diffuser is designed for those looking to add some flair and function to their vehicle. This diffuser is composed of durable Carbon Fiber material which comes in a glossy finish. In addition to being lighter and more aggressive looking, this diffuser also allows for an increase in downforce thanks to its design.
