Size: 15x14Finish: NSHT BlackWheel Material: 6061 T-6Lip: Non-Beadlock, Aero Lip Born from our engineering of an aero-dynamic IMSA endurance wheel, this development concluded not only the aero advantage for Daytona & Lemans, but the lip strength at the tire and bead seat was increased dramatically over a standard lip design. Specifically engineered for the rigors of dirt racing. Details: Forged, precision machined, 6061 aluminum alloy. No wheel halves or silicone. Aero design creates the strongest wheel lip on the track, increased tire de-bead force resistance Engineered anti-rotation marks in tire bead seat are to prevent tire slip rotation Machined lug nut pockets for proper acceleration/braking load distribution Improved valve stem location 5.0” backspace Available in Polished or NSHT Black Optional carbon fiber mud cover and titanium cover bolts
