There is a specific recipe to get this result. And it’s very precise. If you miss it by an inch, you mess things up. You have to start with a BMW M4. Then, you dress it with a wide body kit made by Vorsteiner. It’s probably the perfect kit for the mighty M4, and I’ll tell you why I think so.

First, because it isn’t made of carbon fiber composites, like other kits on the market. No. It’s made of pure, stiff, strong and durable carbon fiber, just like the one used in the aerospace industry. And second, because it fits flawlessly on the M4, looking as if it was made in the BMW factory. Its price? $20,995 MSRP.

But the whole kit would look horrifying without proper wheels. That’s why the custom made HRE performance wheels look absolutely sensational in combination with the wide body kit. They have the perfect diameter to completely fill the wide wheel arch, and the perfect wideness to be aligned to the fenders.

For an even more aggressive stance, and more stability, a hydraulic suspension has been fitted to the car. It can be adjusted at the push of a button, and it’s capable to make a ride around the city as exciting as a fast lap on the track.

But, as we all know, nothing is complete without the proper noise. This is no exception: the exhaust made by Armytrix worth every penny. According to the company, it adds an extra 26 hp and 33 Nm, weighing 3.8 kg less. And the sound…the sound is sensational! Just listen and admire!

Called the GTRS4, the kit is now ready for discerning customers, and the aftermarket specialist released it with a ton of photos.

As pretty much every wide body kit out there, the main point of this project is to drastically alter the visual aspect of the car, and I’d say Vorsteiner managed to do that quite well. That being said, it is not easy to improve on the aspect of a car that is just awesome out the factory.

But just because the GTRS4 kit for the BMW M4 looks awesome, it doesn’t mean it doesn’t also have some functionality. While this might be a bit hard to grasp, it seems that the bigger body parts actually help improve the drag coefficient of the car. In plainest terms, the BMW M4 equipped with Vorsteiner’s kit is better at directing airflow around the car. But enough talking about it and just take a look at the massive photo library provided by the tuner.

Build for the new BMW M4, the wide body kit was previewed earlier and, as expected, is quite awesome.

Named the GTRS4 body kit, the new tuning project looks amazing, a fitting way for the aftermarket specialist Vorsteiner of celebrating 10 years of dedication to tuning BMWs. For those of you that already have seen the previewed clay moldings, not much surprise is left.

The car received very wide wheel arches, along with redesigned front and rear bumpers to go with them. Vorsteiner also fitted the BMW M4 with their GTS carbon fiber front splitter and rear diffuser. A complete new visual overhaul is accomplished by a new set of rims. And for the cherry on top is a nice ECU tune that bring the power up to a reported 550 Hp.
