Reference Information

Wheel, F1M, 18 in. x 10.5, Forged Aluminum, Gloss, Silver, 5 x 4.50 in. Bolt Pattern, 73.1mm Center Bore, +25.00mm Offset, Each

The F1M from Konig Wheels is a forged, mesh design, which has been drastically optimized for increased rigidity, extensive weight savings, as well as its increased ability to withstand fatigue. As the spokes fork in opposing directions, they radius into the outer "C" channel flange which increases the rigidity of the outer wheel edge. Every cut, radius, fillet, chamfer, angle, and shape are all intentionally placed to shave away aluminum where it is not needed, reducing weight and improving the fatigue strength by reducing stress concentrations. All of this is found and confirmed using state-of-the-art Finite Element Analysis. Every wheel comes with an aluminum O-ring center cap and is finished in ash silver. Knurled bead seats come standard to prevent tire slip in high torque applications. The Konig F1M is offered in 4-lug and 5-lug PCS options and are available in many popular sizes to fit most performance vehicles.
