Even with the GTS kit unveiled back in SEMA for the BMW M3 and M4, Vorsteiner is still not done tinkering around the German machine. Focusing their effort on the M4, they had come up with a follow up to the GTS kit with some added goodies, and it is called the GTRS.
Using carbon fiber as their main material, the M4 gets a visual enhancement through the new front bumper that comes with a built-in splitter. The front fenders and aero side blades are also made out of this lightweight material, as well as the rear fenders and bumper which is fitted with a custom diffuser.
The new muscular body is not the only new addition onto the M4 as it also gets 90mm four exhaust pipes which comes with the options of a brushed or diamond black finish. Vorsteiner also offers embroidered floor and mat set, special badging, and a set of three-piece 20-inch glossy rushed shadow alloy wheels wrapped in Pirelli rubber.
As for now, Vorsteiner is not messing around with the engine as the 3.0-liter inline-six power plant still produces 431-horsepower and 406 lb-ft of torque. Fitted with the seven-speed M DCT, the M4 could go from zerotohundred in just 4.1 seconds and has a top speed of 250km/h, or a higher 280km/h with the M Driver’s Package.
