German tuner ABT Sportsline has released a number of upgrades for the current 2013 Audi RS4 Avant. One of the upgrades is the removal of the factory electronic speed limiter. The ABT RS4 is now able to reach a top speed of almost 290km/h. An optionally available stainless-steel exhaust system is the second option on the list. ABT Sportsline replaces the system from the catalytic converter.
The Germans uses their ABT DR design wheels in 9×20 inches. There are finished in gun metal finish and the spokes are arranged like a turbine blade. The Bavarian car tuner also fitted 25mm wheel spacers on each side. The final upgrades are an ABT boot mat and matching set of floor mats.
