The development of aftermarket car parts is an art form. Whenever high-quality craftsmanship becomes part of a conversation, I always instantly think of the aftermarket car industry. Like so many other parts of the business we encounter, there are certainly companies that provide a subpar product. On the other hand, the aftermarket car industry is filled with companies who’s dedication, persistence and attention to details make them unique in a way. Vorsteiner is part of that group.
As you may know, the current generation BMW M4 has been out there for some time now. It is powered by a 3.0 liter TwinPower turbo inline-six engine developing 425 horsepower. This gives the high-performance coupe enough performance to accelerate from 0-62mph (0-100km/h) in just 3.9 seconds for the automatic transmission version of the car. Top speed for this vehicle is 183mph (250km/h) that is electronically limited.
Plenty of pundits will cringe at the mere idea of modifying such a vehicle. BMW did make a rather pretty and aggressive vehicle, all with performance in mind. On the other hand, the need to customize performance cars like these is always something we need to count upon. Making the BMW M4 wider, that’s a completely other game alltogether.
Vorsteiner has painstakingly developed the GTRS4 aero program for the M4. From the computer design phase to the clay modelling, this set of parts was really thoroughly tested and modified, all to create an aero program that fits perfectly on this vehicle. Complete aero kit is made out of carbon fiber, it consists of a front spoiler, front bumpers, side skirts, rear quarter panels and a rear diffuser, all joined by custom made forged three-piece wheels, finished in Sakhir Orange. Grab a few moments to go through the media gallery, there are some rather interesting details of this widebody kit shown there.
