Best Suspension Upgrades for the BMW E82 1M (Road & Track Guide)

In standard form, the 1M does not offer enough front camber adjustment to achieve effective Fast Road or Track suspension geometry settings. This makes it difficult to significantly reduce the amount of understeer experienced at fast cornering speeds.

The 1M adjustable camber plates from Suspension Secrets allow additional negative camber to be dialled into the front axle, significantly improving front-end grip and steering feel.

Why 1M Camber Plates Matter

• Reduce understeer
• Sharpen turn-in
• Increase steering feedback
• Improve tyre wear on track

Suspension Secrets 1M camber plates also increase caster angle, providing dynamic camber gain as steering lock is applied. As well as further improving turn-in response, caster also enhances steering feel and weighting. An added bonus is that Suspension Secrets camber plates are fully compatible with aftermarket coilovers that use the OEM top mounts.

Solid Front Control Arm Bushes

ORDER SOLID BUSHES

BMW equipped the 1M with soft rubber bushes in the front lower control arms. Under braking and cornering loads, these bushes flex. That deflection changes suspension geometry dynamically, which is why the car can feel slightly vague under heavy braking or initial turn-in. 

Replacing them with Suspension Secrets Solid Front Control Arm Bushes eliminates that unwanted movement.

Solid Bushes Improve

• Braking stability
• Steering precision
• Consistency under load
• Front end confidence

The steering feels more direct. The car holds its geometry instead of moving around on soft rubber. For fast road and track cars like the E82 1M, this is one of the most worthwhile upgrades you can make.

Adjustable Rear Toe Arms

With understeer reduced by our 1M front camber plates, it’s important to match these handling gains with improved rear axle geometry.

When applying more negative camber to the rear of the 1M chassis, it reduces the amount of toe angle adjustment available. This ultimately means a compromised rear setup; a small amount of toe-in angle improves rear grip.

Suspension Secrets Adjustable Rear Toe Arms offer:

• Greater adjustment range than OEM arms
• Independent optimisation of camber and toe
• Solid mounting to eliminate flex under load

Furthermore, the last 1M was manufactured in 2012 so it's inevitable that rubber bushes in the arms will have perished. Swapping out the factory arms for our solid-mounted arms achieves a greater level of handling precision and consistency.

BMW E82 1M Suspension Upgrades For Road & Track (Clubsport)

This section covers essential BMW 1M suspension upgrades for track driving. The following parts will add further focus to the E82 chassis, further reducing slack in the car's responses and allowing even greater adjustment of rear geometry for the perfect setup.

Adjustable Rear Upper Camber Arms

ORDER CAMBER ARMS

It is not possible to dial in sufficient camber at the rear of the 1M for a more aggressive suspension setup. That's why you need Suspension Secrets Rear Upper Camber Arms.

• Increase cornering grip and stability
• Wider range of rear camber adjustment
• More consistent rear tyre wear/usage
• Improved corner-exit traction

If running semi-slick or slick track tyres on your 1M, it's important to adjust geometry to maximise handling potential. These rear camber arms provide the adjustment range needed to unlock great trackday settings, and support fast road suspension setups.

Adjustable Rear Upper Third Link Arms

ORDER THIRD LINKS

When fitting adjustable rear camber arms (described above), it's important to combine these upgrade parts with adjustable rear upper third links. These further support the installation of more negative camber to improve handling performance.

Third Links Main Benefits:

• Increase cornering grip
• Offer wider range of camber adjustment than stock
• Stops binding of ball joints and bearings with track-spec camber settings
• Necessary for semi-slick and slick tyre use

The wide range of adjustment offered by our third links also stops tension building in the suspension geometry when applying additional negative camber.

Solid Rear Control Arm Bushes

ORDER SOLID BUSHES

The 1M can feel unruly at times as the rear axle struggles to transfer the in-line six's 340hp to the road effectively. When the 1M is driven at high speed, rubber bush flex at the rear axle also creates instability that affects driver confidence.

Suspension Secrets Solid Rear Control Arm Bushes are a direct replacement for the OEM rubber bushes and stop unwanted flexing. This means camber and toe settings no longer change when the car is driven hard, increasing overall predictability.

Full 1M Solid Bush Benefits:

• Increased rear axle stability
• Improved rear axle responsiveness
• Increased cornering grip
• More precise handling

By fitting solid bushes at the rear of the 1M, BMW's super coupe enters, transits through and exits corners with much greater control.

Adjustable Front & Rear Drop Links

ORDER DROP LINKS

The ride height of a BMW 1M can be lowered by aftermarket springs or coilover systems for fast road and track driving. However, this often causes the anti-roll/sway bars to make contact with the chassis.

Our Suspension Secrets front and rear drop links stop this contact from happening. They are also a useful addition if you are corner weighting your 1M as they ensure the anti-roll bars stay level and don't create unwanted tension.

1M Drop Links Benefits:

• Fully adjustable
• Easy to install and adjust
• Complete control over anti-roll bar positioning
• Removal of tension and uneven ARB

Front and rear drop links are an important detail in ensuring your E82 1M remains safe as it transitions from standard car to fast road or track machine.

BMW E82 1M Suspension Upgrades for Track

The final section of this BMW 1M suspension tuning guide focuses on modifications for serious track work. We would recommend only fitting these parts if you are taking your 1M on circuit.

Front Offset Caster Bushes

ORDER CASTER BUSHES

Our Suspension Secrets Front Offset Caster Bushes are a step up from the solid front bushes described in the Fast Road section of this guide.

As well as replacing the factory rubber bushes to stop unwanted flexing, these 1M suspension upgrade parts adds positive caster. This increases camber gain as the steering wheel is turned, which further improves cornering grip and reduces understeer.

Positive caster also enhances steering weight and communication, which is key for any car driven on circuit.

Adjustable Rear Billet Traction Arms

ORDER TRACTION ARMS

Traction is key to achieving great lap times, and the standard 1M's sheer firepower can make it a handful at the limit. 

Rear traction arms from Suspension Secrets are shim-adjustable and make the rear axle more reactive to throttle inputs while improving overall stability. 

1M Rear Traction Arms Benefits:

• Improved acceleration
• Increased straight-line stability
• More responsive rear axle
• Increased corner-exit traction
• Higher corner exit speeds

Our adjustable rear traction arms achieve these benefits by changing the way the rear suspension moves when the 1M squats under power. By fitting the shims inside the traction arms, the suspension's path of movement is adjusted and pushes the front edge of the tyre harder into the road surface. This means even more mechanical grip.

Solid Rear Subframe Bushes

ORDER REAR BUSHES

Despite its status as a hardcore performance BMW, the 1M has many soft rubber bushes in its suspension. Four of these are located between the rear subframe and main chassis. 

These large bushes flex during fast driving, and particularly on track where other suspension upgrades might be generating even greater G-forces than a stock setup. This situation makes solid bushes critical to maintaining control and predictability. 

Rear Subframe Bushes Benefits:

• Improved cornering stability
• Enhanced chassis response and feedback
• Reduced oversteer

With solid bushes fitted between subframe and chassis, drivers will also notice much keener response from the rear axle to both throttle and steering inputs. The trade-off is an increase in NVH, but for track purists these 1M solid bushes are well worth it.

H&R Anti-Roll Bar Kit

ORDER ANTI-ROLL BARS

The 1M's standard anti-roll bars are designed to suit a broad range of road conditions and drivers. However, when the car is lowered and upgraded with aftermarket suspension parts, body roll can become more noticeable. This affects suspension geometry and handling precision.

The H&R Anti-Roll Bar Kit includes thicker bars than stock to correct this problem. The 1M's factory anti-roll bars measure 26.5mm (front) and 22.5mm (rear). Whereas the H&R bars measure 27mm (front) and 23mm (rear).

Thicker Anti-Roll Bar Benefits:

• Reduced body leaning for flatter and more stable cornering
• More consistent geometry for sharper turn-in response
• Fine-tuning of handling to reduce oversteer/understeer
• Increased body control in fast transitions

Thicker anti-roll bars alone don't increase grip - by controlling body movements they help the tyres use their grip more effectively. Anti-roll bars are great for dialling in sharper and more predictable handling on the road and track.

Nitron R3 Coilovers

ORDER NITRON COILOVERS

For BMW 1M owners wanting to maximise suspension tuning and performance, we recommend installing 3-way Nitron R3 coilovers.

The R3 coilover system is adjustable in high- and low-speed compression, rebound and ride height. In a nutshell, 3-way adjustable coilovers allow you to control grip level, chassis balance, comfort level and stability - independently of each other. This is why they're used in professional motorsport.
