Vorsteiner has put a lot of work into making a kit that doesn’t really disrupt to original lines of the M5. Arguably, that’s the most important part of building a kit. It’s easy to make a kit that’s really loud, but they almost always look terrible. Luckily, Vorsteiner doesn’t fall into that trap.
The kit includes carbon fiber front and rear spoiler, a light weight trunk lid, and a completely re-done rear diffuser. These parts will likely help with downforce, but really, they have more to do with improving the look of the car than they do performance. Though, that Vorsteiner exhuast probably frees up a few horsepower. Those 20″ wheels, however, are pure eye candy.
