SEMA 2014: Vorsteiner Debuts The GTRS4 BMW M4 Conversion
Vorsteiner is known for their BMW tuning and back when the E9X M3 came out they blew everyone’s minds with their GTRS3 widebody conversion that added some significant junk in the M3’s trunk (no pun intended). When BMW released the new M4 coupe many were wondering how long it would take for Vorsteiner to work their widebody magic or if they would even do it at all. Well right now at SEMA Vorsteiner has answered those questions with “yes” and “right now” as they revealed the GTRS4 (the 4 is for M4…get it?).
When Vorsteiner was creating the GTRS4 conversion they wanted to go for something that was still aggressive but not quite as wild as what they did with the GTRS3. On lookers will notice that when comparing the GTRS4 to the GTRS3 the S4 has very few hard lines or angles. Its much smoother and more in harmony with what BMW was already going for when they designed the M4. I would almost go as far to say that the GTRS4 looks like something BMW created themselves, which is a testament to how good Vorsteiner’s body design artisans are. Despite its harmonious looks the GTRS4 conversion actually adds an additional 4 inches of width to the front of the car and a whopping 7 inches of width to the rear.
With fenders that wide it would take a special wheel to fill it. Luckily since Vorsteiner also produces wheels they created a forged three-piece specifically for the GTRS4 finished in “Gloss brushed shadow”. The 20 inch wheels are 10.5 inches wide in the front and 13 inches wide in the rear which contributes to a massive footprint left behind by the Pirelli tires adorn the rollers.
Naturally all of the body pieces on this conversion are made from Vorsteiner’s patented carbon fiber. With many wide body kits these days made from fiberglass, its crazy to the think that Vorsteiner sticks to their guns and always uses carbon. Its also crazy to think how much this set up will probably cost due to the quality of the materials used. There aren’t many performance mods on this particular GTRS4 but the mods that were done certainly count. First, a KW Suspension system was bolted on which gives the GTRS4 its low stance. Then, Vorsteiner turned to ESS Tuning for a special ECU flash that bumps the horsepower to 550HP at the crank. However those performance bits are not included as part of the package. Everything else you see (including some special edition badges and interior bits like floor mats), is included.
Even though this is only the debut of the GTRS4 and Vorsteiner has not “officially” began taking orders, as of this post I know of at least one confirmed customer of the kit so far. Although I am sure that number has likely gone up significantly since the car has been seen by thousands of people online and on the SEMA show floor. Again, pricing and availability of the GTRS4 is still unknown at this point but I already know for sure its WAY more than I can afford! If you are in the same boat then dream with me by checking out some official pics and live pics from the SEMA show!
