Suspension Secrets Adjustable Rear Toe Arms / Links - BMW F22 M235i/M240i

Suspension Secrets Adjustable Rear Toe Arms / Links – BMW F22 M235i / M240i

Increase rear axle stability, traction and geometry control with Suspension Secrets Adjustable Rear Toe Arms for the BMW F22 M235i and M240i.

The factory BMW rear toe arms use large rubber bushes which can flex during hard cornering and acceleration. This movement allows the rear toe angle to change dynamically, making the rear axle feel less stable and less predictable when the car is being driven hard.

Suspension Secrets Adjustable Rear Toe Arms replace this compliant arrangement with fully adjustable, spherical rose-jointed arms designed to keep the rear toe angle far more consistent under load.

The result is improved traction, greater stability and a more direct connection between throttle input and rear axle response.

Why Upgrade the Rear Toe Arms?

Rear toe plays a major role in traction, stability and overall rear axle behaviour.

Reducing unwanted toe movement can help provide:

• Increased cornering stability
• Improved straight-line traction
• Better acceleration response
• More positive rear axle feedback
• Greater geometry consistency
• Increased rear toe adjustment range
• Easier setup changes
• Improved compatibility with increased negative camber

The Problem With the Factory Toe Arms

The original BMW rear toe arms use large rubber bushes to improve comfort and refinement.

Under high loads, these bushes can flex.

This allows the rear suspension geometry to move away from the static alignment settings during:

• Hard cornering
• Aggressive acceleration
• Launches
• Track driving

The result can be unwanted rear toe changes and reduced confidence in the rear axle.

Reduced Dynamic Toe Change

The Suspension Secrets arms use solidly mounted spherical rose joints rather than compliant rubber bushes.

This helps keep rear toe more consistent as suspension loads increase.

Potential benefits include:

• More stable rear geometry
• Improved traction
• More predictable cornering
• Better rear axle control

Increased Cornering Stability

Unwanted rear toe changes can make the car feel nervous or inconsistent through corners.

Keeping the toe angle more stable helps the rear axle behave more predictably as lateral load builds.

This can result in:

• Better mid-corner confidence
• More consistent rear grip
• Improved high-speed stability
• Greater chassis predictability

Improved Acceleration

Factory bush deflection can create a slight delay between applying the throttle and feeling the rear axle respond.

Reducing this compliance allows acceleration forces to be transmitted more directly through the suspension.

This can provide:

• Sharper rear axle response
• More immediate feedback
• Improved sense of connection
• More consistent traction

Ideal for Tuned Cars

The benefits become increasingly relevant as engine output rises.

Higher torque places greater load through the rear suspension, increasing the potential for rubber bush deflection.

These arms are therefore particularly useful for:

• Tuned M235i models
• Tuned M240i models
• High-torque builds
• Drag-focused cars
• Fast-road performance setups

Improved Straight-Line Traction

Keeping the rear wheels more consistently aligned under acceleration can help the tyres put power down more effectively.

This makes the arms particularly useful for:

• Tuned road cars
• Drag builds
• Roll-racing setups
• High-power F22s

Greater Rear Toe Adjustment

The Suspension Secrets arms provide a wider adjustment range than the factory components.

This allows rear toe to be tailored far more precisely.

This is particularly valuable when:

• The car is lowered
• Increased negative camber is used
• Track geometry is required
• Tyre size or setup has changed

Works With Increased Rear Camber

When more negative rear camber is introduced, the toe setting can also be affected.

The additional adjustment range helps maintain the desired rear toe angle while running more aggressive camber settings.

This makes the arms a useful companion to:

• Adjustable rear camber arms
• Adjustable rear upper third links
• Coilovers
• Track-focused geometry

Easy In-Situ Adjustment

Suspension Secrets designed the arms to make setup changes straightforward.

The stainless steel adjusters can be altered using a 17mm spanner.

This allows quicker and more accurate rear toe changes during:

• Wheel alignment
• Track setup
• Geometry refinement
• Workshop adjustment

6082 T6 Aluminium Construction

The main arm bodies are manufactured from billet aircraft-grade 6082 T6 aluminium.

This provides a strong, lightweight structure suitable for demanding road and motorsport use.

316 Stainless Steel Components

Corrosion-resistant 316 stainless steel is used throughout the adjusters and associated componentry.

This helps improve durability in an exposed suspension environment.

Motorsport-Spec Fluro Bearings

Suspension Secrets uses motorsport-spec Fluro bearings to provide precise articulation and long-term performance under demanding suspension loads.

Road & Track Applications

The adjustable rear toe arms are suitable for:

• Fast-road builds
• Clubsport cars
• Trackday vehicles
• Tuned road cars
• Drag-oriented builds
• Performance geometry setups

NVH Considerations

Because these arms replace compliant rubber-bushed components with spherical rose joints, some increase in noise, vibration and harshness may be possible.

This is a performance-focused upgrade intended for drivers prioritising rear axle precision and geometry control.

Works Well With Other Suspension Upgrades

These arms pair particularly well with:

• Adjustable rear camber arms
• Adjustable rear upper third links
• Adjustable rear traction arms
• Solid rear control arm bushes
• Coilovers
• Uprated anti-roll bars
• Performance geometry setups

Professional Installation Recommended

Professional installation is recommended.

After fitting, the vehicle should receive:

• Suspension inspection
• Rear toe adjustment
• Rear camber check
• Full wheel alignment
• Fastener checks

Geometry Setup Essential

A professional geometry setup should be carried out after installation.

Rear toe should be configured alongside:

• Rear camber
• Ride height
• Tyre choice
• Road or track use
• Desired handling balance
