GTRS4 BMW M4 by Vorsteiner

 »  »  »

Vorsteiner, one of the most respected aftermarket specialists, are celebrating their 10th anniversary this year. To mark this occasion, they have developed this new body kit for the M4 Bimmer, which is called the GTRS4. The world debut of Vorsteiner's GTRS4 package for the BMW M4 is going to take place at this year's SEMA show in Las Vegas. The Vorsteiner GTRS4 is a carbon fiber full wide body kit, which took almost a whole year to develop. When doing it, Vorsteiner took into consideration design language, functionality, performance, and everyday drivability. Usually, these wide body kits are nice to look at, but difficult to live with on a day-to-day basis. Vorsteiner went to great lengths to make sure you'll be able to drive your GTRS4 daily.

The Vorsteiner GTRS4 is 4 inches wider than a regular M4 at the front, and 7 inches wider at the rear. They designed a special set of 3-piece forged wheels that measure 20x10.5J and 20x13.5J and can take 275 and 345 wide tires. The Vorsteiner GTRS4 BMW M4 you're going to see at SEMA has Pirelli P Zeros. It also features a KW suspension that allows it to keep the original BMW Dynamic Drive features.



Vorsteiner's GTRS4 wide body kit for the BMW M4 includes a new front bumper with an integrated splitter, wider fenders with vents for the brakes, aero side blade elements, and a rear diffuser. The Vorsteiner GTRS4 BMW M4 is also fitted with a quad exhaust with 90mm pipes, which can be finished in brushed aluminum or diamond black, and Brembo brakes.

The one thing we somehow "forgot" to mention, is that the Vorsteiner GTRS4 is also equipped with an ESS Tuning E-Tronic power upgrade. It increases the output of the 3.0-liter twin-turbocharged engine from 431 hp to 550 hp at the crank.

Vorsteiner is going to announce the price and availability of the GTRS4 program for the BMW M4 at a later date.
