I don't know about the Konigs but I've been very happy with my Pro Race 1.2's. I love that they are over 5 lb. lighter than stock in stock 17 x 7 size, that they have a stock center bore size so don't need centering rings, and come in a variety of offsets. I also think they look nice.
I got curious and looked at the Konig site. They wouldn't have been for me because the narrowest 17 shown is an 8" wheel, and I wanted stay with a stock size wheel and not change the handling characteristics of this beautifully set up car. I also don't see any 16's. The 17 x 8 they show is lighter than the comparable Pro Race 1.2.
