The Mercedes-AMG GT R is fast becoming a popular choice with tuners. The latest is this extreme example: the Domanig GT R.

Yes, as MB Passion Blog points out, Germany's Domanig Autodesign has given Affalterbach's GT R quite a makeover. With a little help from fellow German firm IMSA, the 4,0-litre V8's power output has been hiked from the standard 430 kW and 700 N.m to a whopping 574 kW and 960 N.m. The result is a claimed 0-100 km/h time of just 2,9 seconds (an improvement of seven-tenths of a second) and a top speed of 330 km/h.

These new outputs were achieved thanks to a pair of stronger turbochargers, double-flow exhaust manifolds, downpipes with a sports catalyst and a sports air filter. In addition, the engine and transmission were re-calibrated and an additional radiator for the low-temperature cycle of the intercooler was added. The transmission was also reinforced to withstand the increased torque output.

So, what else has been done? Well, a set of KW springs were added, making the GT R some 30 mm closer to the ground (the front axle can be raised by 30 mm to overcome speed bumps and such thanks to a lift system). The company says the new suspension setup does not interfere with the GT R’s standard damper settings.

A set of Domanig D-Ultralight Black Edition forged wheels add to the intimidating stance, while retaining the standard Michelin Pilot Cup 2 tyres. Apart from the yellow livery, the rest of the exterior remains as is.
