The GTRS4 below is a fantastic showcase for Vorsteiner's carbon-fiber skills.
But most owners will prefer something much more subtle -- and perhaps the flexibility to fit the M3 as well as the M4 coupe.
Vorsteiner's GTS has a few upgrades in the catalog so far: wheels, exhaust finishers, and fantastic front and rear CF aero additions. Check out the photos below in white to see the Vorsteiner GTS!
Vorsteiner M4 and M3 GTS
A SEMA show car for the road? And one that any M4 owner can add to his or her prized supercoupe?
Enter, the Vorsteiner M4 GTRS4 Widebody -- a carbon-fiber kit so outrageous and sexy, the rear wheels look like steamrollers. Fenders so huge that this looks more like an M4 dually?
Overall, the GTRS4 is 3.5-inches wider on both sides in back, and 2-inches wider per side in front. Overall, the performance enhancement offered by the GTRS4 is a huge upgrade in the grip available. Most rubber widths are constrained by the overall size and clearance of the fenders, but this kit solves for that very elegantly.
The included elements of the new GTRS4 package are below - with first orders coming in early 2015.
