Willspeed AE B6.3 Take One D Arm Mount (Black) – WSA-06-B

The Willspeed AE B6.3 Take One D Arm Mount in black (WSA-06-B) is designed for carpet racing where precision rear geometry pays off. By removing 1° of inboard rear toe compared with the standard D hanger, it enables 0.5° and even 0° inboard toe without altering anti-squat adjustment.

This change lets the rear axle work more efficiently, reducing tyre scrub, boosting mid-corner rotation and increasing on-power steering to help unlock those last tenths.
