Adjustable Rear Trailing Arms – BMW M2 / M3 / M4

Description

Acceleration stability and traction are strongly influenced by the anti-squat characteristics of the rear suspension. These adjustable rear trailing arms incorporate additional anti-squat adjustment, allowing the suspension geometry to be tuned according to grip level, power output and driving style.

By controlling how the rear suspension reacts under acceleration, unwanted rear axle squat is reduced, improving traction on corner exit while maintaining stable and consistent rear axle geometry under load.

This solution allows drivers to precisely fine-tune rear axle behaviour for circuit racing, time attack and controlled rear-end rotation — particularly when running high-grip tyres or increased power levels.

Key Features

• additional rear axle anti-squat adjustment
• improved traction under acceleration
• reduction of unwanted rear suspension squat
• stable and repeatable rear axle geometry under load
• geometry tuning adapted to grip level, power output and driving style

Construction

The trailing arms are fully adjustable and CNC machined from 6082 aluminium. Motorsport-grade spherical bearings eliminate compliance under load, while stainless steel components ensure reliability in harsh track environments.
