The American tuning company Vorsteiner has brought to this year’s SEMA Motor Show an upgraded BMW M4 Coupe. The special edition vehicle was designed to celebrate Vorsteiner’s 10th anniversary.
The tuning kit is called GTRS4 and includes carbon fiber components for the bumpers, the wide fenders and the aero side blades. There are also 90mm quad exhaust tailpipes with a brushed or diamond black finish.
This BMW M4 GTRS4 benefits from a KW Suspension’s sleeve kit that allows for height adjustment and is riding on three-piece 20-inch alloy wheels with a gloss brushed finish, wrapped in Pirelli P Nero tyres for optimized traction and performance. It features Vorsteiner chrome trunk badging as well.
In the powertrain department, the stock 3.0-litre inline-six TwinPower Turbo engine has been upgraded with ESS Tuning’s E-Tronic module and sports a power boost from 431 hp to 550 hp. The performance figures have not been released yet.
On the inside, the one-off model comes with Vorsteiner embroidered coloured floor and trunk mats.
