Between you and me, I don't know what ECO1 stands for, but this is a kick-ass wheel. It is offered in Matte Black or a Matte Titanium finish. This wheel is lightweight and good for the street/track, weekend warrior. Offered sizes are 15x6.5 and 17x7, this is another one of our favorites.
Konig Eco1 wheels available in the following sizes and colors (Price is for a set of 4 wheels):
15x6.5 (matte black/matte titanium)
17x7 (matte black/matte titanium )
