Suspension Secrets Adjustable Front Drop Links / End Links - BMW F20 M135i/M140i

Suspension Secrets Adjustable Front Drop Links / End Links – BMW F20 M135i / M140i

Restore correct front anti-roll bar positioning and improve side-to-side handling consistency with Suspension Secrets Adjustable Front Drop Links for the BMW F20 M135i and M140i.

Lowering the F20 on springs or coilovers can alter the resting position of the front anti-roll bar because the factory fixed-length drop links are no longer operating at the original ride height.

This can introduce unwanted tension into the anti-roll bar, affect handling consistency from left to right and, in some setups, create clearance issues between the anti-roll bar and other suspension components.

Suspension Secrets Adjustable Front Drop Links allow the effective link length to be corrected, helping return the anti-roll bar to a more suitable position and restore more predictable front-end behaviour.

Why Upgrade to Adjustable Front Drop Links?

Adjustable front drop links are a useful supporting upgrade for lowered and performance-focused F20 builds.

Potential benefits include:

• Restored front anti-roll bar position
• Reduced unwanted anti-roll bar preload
• More even handling left-to-right
• Improved steering predictability
• Reduced risk of suspension component contact
• Better setup on lowered cars
• Useful for corner weighting
• Suitable for road and track applications

Correct Front Anti-Roll Bar Geometry After Lowering

Lowering the vehicle changes the relationship between the suspension and anti-roll bar.

When the original fixed-length drop links are retained, the anti-roll bar can be pulled away from its intended resting position.

Adjustable links allow the connection length to be altered to suit the revised ride height, helping restore more appropriate anti-roll bar geometry.

Reduce Anti-Roll Bar Preload

If the front anti-roll bar is held under tension while the vehicle is sitting level, this can influence how the suspension responds from one side of the car to the other.

Correctly adjusted drop links help remove this unwanted preload.

This can result in:

• More balanced handling
• More consistent steering response
• Improved suspension behaviour
• Greater predictability

Improved Left-to-Right Handling

One of the main benefits of correctly setting the front anti-roll bar is improved consistency.

Unwanted anti-roll bar preload can make a car behave differently in left-hand and right-hand corners.

Adjustable drop links help create a more neutral setup so the front suspension can respond more evenly in both directions.

Increased Steering Predictability

The front anti-roll bar is closely linked to the way the front axle responds during cornering.

Correcting its position can help create a more consistent relationship between steering input and chassis response.

Potential benefits include:

• More predictable turn-in
• Improved steering consistency
• Better front-end confidence
• More balanced handling

Helps Prevent Component Contact

On some lowered suspension setups, the altered anti-roll bar position can reduce clearance to nearby suspension or chassis components.

In more extreme cases, this can result in contact as the suspension moves.

Adjustable drop links allow the anti-roll bar position to be corrected, helping reduce the risk of unwanted interference.

Ideal for Lowering Springs & Coilovers

These links are particularly useful for F20 models fitted with:

• Lowering springs
• Height-adjustable spring kits
• Coilovers
• Uprated anti-roll bars
• Track-focused suspension

Any meaningful ride-height change can alter the operating position of the factory anti-roll bar system.

Ideal for Corner Weighting

Adjustable front drop links are especially useful on cars that have been corner weighted.

Corner weighting can result in slightly different ride heights at each corner of the vehicle.

If fixed-length drop links are retained, these differences can introduce tension into the anti-roll bar and affect the final setup.

Adjustable links allow the front anti-roll bar to be neutralised at the finished ride heights.

Billet 6082 T6 Aluminium Construction

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

This provides a combination of:

• High strength
• Low weight
• Durability
• Performance-focused construction

316 Stainless Steel Components

Corrosion-resistant 316 stainless steel is used for the associated hardware and adjustment components.

This makes the links better suited to long-term use in an exposed suspension environment.

Motorsport-Spec Fluro Bearings

Suspension Secrets uses motorsport-spec Fluro bearings within the drop links.

These are designed to provide precise articulation and durability under demanding suspension loads.

Road & Track Applications

The adjustable front drop links are suitable for a wide range of builds, including:

• Lowered daily drivers
• Fast-road cars
• Clubsport builds
• Trackday cars
• Corner-weighted vehicles

Works Well With Other Suspension Upgrades

The links are particularly effective alongside:

• Coilovers
• Lowering springs
• Uprated anti-roll bars
• Camber/caster plates
• Adjustable suspension arms
• Performance geometry setups

They allow the anti-roll bar system to be set correctly around the rest of the suspension package.

Professional Setup Recommended

Although adjustment is straightforward, the final link length should be set correctly for the vehicle's ride height and suspension configuration.

For performance applications, setup by an experienced suspension or geometry specialist is recommended.
