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

Suspension Secrets Adjustable Rear Upper Third Link Arms – BMW F22 M235i / M240i

Increase rear cornering grip, stability and geometry range with Suspension Secrets Adjustable Rear Upper Third Link Arms for the BMW F22 M235i and M240i.

The factory rear upper third links are fixed-length components. When higher levels of negative rear camber are introduced using adjustable rear camber arms, the standard third links can be forced into an unfavourable position and placed under additional tension.

Suspension Secrets developed these adjustable third link arms to remove that limitation, allowing the rear suspension to accommodate more aggressive camber settings with less risk of binding through the associated joints and bearings.

Why Upgrade the Rear Upper Third Links?

These arms are particularly useful on track-focused F22 builds where increased rear camber is required.

Potential benefits include:

• Wider rear camber adjustment range
• Reduced suspension binding
• Improved cornering grip
• Increased rear axle stability
• Better mid-corner traction
• Improved corner-exit traction
• More balanced rear geometry
• Better compatibility with aggressive track alignment

Key Features

• Fully adjustable rear upper third link arms
• Allows greater rear camber adjustment
• Reduces binding at aggressive camber settings
• Helps improve rear cornering grip
• Improves rear axle stability
• Suitable for track-focused geometry
• Billet aircraft-grade 6082 T6 aluminium
• Corrosion-resistant 316 stainless steel
• Motorsport-spec Fluro bearings
• Designed and manufactured in the UK

The Limitation of the Factory Third Links

The OEM rear upper third links are not adjustable.

This is generally acceptable at standard geometry settings, but issues can arise when significantly more negative rear camber is added.

Because the fixed-length third link cannot compensate for the new suspension position, it can become loaded or twisted relative to the rest of the rear suspension.

Designed for Aggressive Rear Camber

The Suspension Secrets adjustable design gives the rear suspension the extra freedom required when running more aggressive camber settings.

This makes the arms especially relevant for cars fitted with:

• Adjustable rear camber arms
• Coilovers
• Track geometry
• Semi-slick tyres
• Slick tyres

Reduced Binding

One of the main reasons to fit adjustable third links is to reduce unwanted binding through the rear suspension.

Aggressive alignment settings can place the factory joints and bearings at less-than-ideal operating angles.

Adjustable third links allow the suspension to be repositioned more appropriately, helping the joints operate with less tension.

Increased Rear Camber Range

The arms allow a greater overall range of rear camber adjustment compared with the standard suspension.

This gives the geometry specialist more freedom to configure the rear axle around:

• Tyre choice
• Ride height
• Track use
• Driving style
• Desired chassis balance

Improved Cornering Grip

Additional negative rear camber can help the outside rear tyre maintain a better contact patch during hard cornering.

When used as part of a correctly configured suspension setup, this can contribute to:

• Increased mid-corner grip
• More stable rear behaviour
• Greater confidence at the limit

Improved Corner-Exit Traction

The rear axle must transition from lateral cornering load into acceleration as the car exits a bend.

A well-configured geometry setup helps the tyres maintain more consistent contact throughout this transition.

The adjustable third links support more aggressive camber settings without forcing the rest of the suspension into an unfavourable position.

Increased Chassis Balance

Rear camber has a significant influence on overall handling balance.

Additional geometry freedom allows the rear axle to be matched more closely with the front suspension setup.

This can help create:

• More neutral balance
• Better rear stability
• More predictable rotation
• Improved confidence at speed

Ideal for Semi-Slick & Slick Tyres

Higher-grip tyres generate significantly greater cornering loads than conventional road tyres.

To make proper use of semi-slick or slick tyres, the suspension often requires more aggressive camber settings and greater geometry control.

These adjustable third links help provide the range needed for those setups.

Works With Adjustable Rear Camber Arms

These arms are best viewed as a supporting component for a more complete rear geometry package.

They work particularly well alongside:

• Suspension Secrets Adjustable Rear Camber Arms
• Adjustable Rear Toe Arms
• Adjustable Rear Traction Arms
• Solid Rear Control Arm Bushes
• Coilovers
• Performance geometry setups

6082 T6 Aluminium Construction

Suspension Secrets manufactures its suspension components from billet aircraft-grade 6082 T6 aluminium.

This provides a strong, lightweight structure suitable for demanding road and track applications.

316 Stainless Steel Components

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

This helps improve durability in an exposed suspension environment.

Motorsport-Spec Fluro Bearings

The arms use motorsport-spec Fluro bearings to provide precise movement and long-term performance under demanding suspension loads.

Track-Focused Application

These arms are primarily intended for cars running more aggressive geometry than would typically be used on a standard road car.

They are particularly suited to:

• Trackday cars
• Clubsport builds
• Semi-slick tyre setups
• Slick tyre setups
• Dedicated performance geometry

NVH Considerations

Because these arms use motorsport-oriented bearing construction rather than soft factory rubber, some increase in noise, vibration and harshness may be possible compared with standard suspension components.

This is a performance-focused upgrade intended to prioritise geometry control and chassis precision.

Professional Installation Recommended

Professional installation is strongly recommended.

The arms should be fitted and adjusted as part of a complete suspension geometry setup.

Geometry Setup Essential

A full performance alignment should be carried out after installation.

Rear camber, toe and associated arm lengths should be set together rather than adjusted independently.

The final settings should be chosen around:

• Tyre type
• Ride height
• Track use
• Coilover setup
• Driver preference
• Desired handling balance
