The Audi (B5) RS4's factory widebody allows for an aggressive wheel fitment. While the Hartmann Wheel line-up likes to boast a sportier fitment over the factory inspired options, wheel width is somewhat limited from the Audi fitment Hartmann Wheel selection. However, H&R wheel adapters allow us to step out of the proverbial box and run wheels we would otherwise throw on the back of a Porsche 911 - 19x10" Hartmann HPO-310-MBM Wheels.
The wheels are wrapped with 275/35 rubber while 20mm front and 30mm rear H&R wheel adapters allow the wheels to fit snug beneath those wide arches. There's room to come out a bit more up front (with say, a 25mm adapter) but it was probably best to play it safe and not test fate by allowing tires to come into contact with the now non-replacable fenders.
