The 3Racing SAK-U410/V2/BK rear suspension mount is intended for competitive drivers wanting a more rigid rear mounting platform. It reduces mounting point deflection to preserve alignment under cornering loads, improving predictability during aggressive driving.
With the SAK-U410/V2/BK in place, suspension geometry remains more consistent lap after lap, which helps when dialing in damping, spring rates, and anti-squat settings. The improved stability aids precise adjustments for camber gain and toe control.
This component fits Sakura Ultimate rear assemblies directly and uses the stock mounting locations. When fitting, ensure fasteners are torqued to spec and recheck geometry before final practice runs to validate your tuning changes.
