Mach V Crucial 18x9.5" 5x114

  • New! Mach V Crucial is a ten-spoke 18x9.5" wheel we developed with the goals of great looks, light weight, and high strength. Of course it has to fit Subarus perfectly, too. We think we succeeded on all fronts. The weight comes in at 19.5 pounds. The wheels clear all Subaru Brembo brakes, including both four-pot and six-pot.

    Crucial is made using flow forming technology. Unlike gravity casting where liquid metal is poured into a mold, in flow forming the wheel material is heated until it is nearly liquid and then it is formed into its shape under pressure. This technique results in a wheel that is lighter and stronger than a conventional cast wheel, and almost as strong as a forged wheel, but without the high cost of forging.

    Other high-end details we added including knurling of the barrel to prevent the tire rotating against the wheel under high load conditions. We also milled away material on the sides of the spokes to further reduce weight. We thickened up the inner lip for extra strength, too. Because we're extra-proud of this wheel, we put our Mach V Motorsports name and the words "flow formed" around the outer edge.

    Offset is +42, which is a nice compromise that allows running a wide tire, but also gets the edge of the wheel out flush with the edge of the fenders. We suggest a 265/35R18 tire on 2008-2014 STI or 2015+ WRX/STI. The 2015+ cars can also run a 255/40R18.

    Hub bore is 73mm; we include hubcentric rings at no charge. Accepts TPMS sensors. Color-matched Mach V logo center caps are included. 5x114 bolt pattern fits all 2005+ WRX STI, 2015+ WRX, and other 5x114 cars.

    Choose from gold, gloss black, gloss gunmetal, and satin gunmetal colors.
