F8X M3/M3/M4 Hardrace Rear Toe Arms

Hardrace Rear Toe Arms - BMW F8X / G8X M2, M3 & M4

Hardrace adjustable rear toe arms replace the factory rear toe links, giving you a greater and more precise range of toe adjustment while replacing the compliant factory joint with a rose jointed design.

The rose joints reduce movement and deflection in the rear toe link under load, helping the rear wheels maintain their intended geometry through hard cornering, braking and acceleration. Combined with the additional adjustment range, this makes them particularly well suited to lowered and track-focused cars where accurate and consistent rear geometry becomes increasingly important.

What it’s good for

Ideal for F8X and G8X M2, M3 and M4s running lowered suspension or more aggressive fast road and track alignments. The increased adjustment range makes it easier to achieve your desired rear toe settings, particularly when changes to ride height and camber have moved the geometry beyond the useful range of the factory arms.

The rose jointed construction also makes them particularly beneficial on track, reducing compliance in the rear suspension and helping maintain a more consistent toe setting as the suspension is loaded.

What we like about it

You’re getting two useful upgrades in one. There’s additional adjustment for properly setting the rear geometry, while the rose joints remove some of the compliance found in the standard setup.

For a more track-focused build, this gives you greater control over the alignment and helps the rear of the car respond more consistently to driver inputs.

Worth knowing

Rose joints trade some refinement for precision. Compared with a rubber-bushed factory component, they can transmit more noise and vibration into the car and will generally require more inspection and maintenance.
