Willspeed Take One D Arm Mount for Yokomo YZ-2 (WSY-05)

The Willspeed YZ2 Take One D Arm Mount (WSY-05) is a popular tuning hanger for carpet racing with Yokomo YZ-2 platforms. By removing 1° of inboard rear toe at the D position, it unlocks finer geometry options, including 0.5° and even 0° inboard toe settings, while maintaining your anti-squat adjustments.

This change allows the rear axle to work more efficiently, helping to reduce tyre scrub, increase mid-corner rotation and enhance on-power steering—ideal traits for high-grip carpet tracks where precision and rotation are key.
