Konig Hyperspec 17x8 5x114.3 ET40 Matte Bronze Wheel (Knurled Bead) for Nissan 350Z, Infiniti G35, Mazda RX8
The Konig Hyperspec 17x8 wheel features flow-formed construction and knurled bead seats for track-ready performance. It bolts on to 5x114.3 vehicles like 2003-2009 Nissan 350Z, 2003-2007 Infiniti G35, and 2004-2011 Mazda RX8 with its ET40 offset and 72.6mm hub bore.
