Today we get the change to revisit a very nice tuning kit from Vorsteiner. We talk about the GTRS4, a package for the BMW M4 that was unveiled few months ago. Even though the kit is not new, the following photo gallery lets us get a closer look at the heavily modified car.

To begin with, the BMW M4 features this lime green finish, extended wheel arches, new front bumper with large air intakes as well as a revised spoiler lip.

The front grille gets a black finish while the new side skirts and rear diffuser also stand out. Inside the revised rear bumper you will see the quad-pipe exhaust too.

The roof also received a black finish while the hood gets a black stripe. In these photos, we can only see exterior styling improvements but we do know that there aren’t any tweaks under the hood.

It’s almost pointless to say that the stock 3.0-liter engine offering 420 horses is already quite good for an ultimate driving experience. With this been said, be sure to check the photo gallery for an in-depth look at the German machine.
