Suspension Secrets Adjustable Rear Upper Camber Arms - BMW 1M

Suspension Secrets Adjustable Rear Upper Camber Arms – BMW 1M

Increase rear cornering grip, traction and geometry adjustability on your BMW E82 1M with Suspension Secrets Adjustable Rear Upper Camber Arms.

The factory eccentric camber adjustment offers only a limited range, which can become restrictive on lowered or track-focused cars. Suspension Secrets developed these adjustable upper arms to provide a much wider range of negative rear camber adjustment, allowing the rear geometry to be set more accurately around the intended use of the car.

Greater Rear Camber Adjustment

The standard BMW eccentric camber bolts provide enough adjustment for normal road use, but they can become limiting when more aggressive alignment settings are required.

These adjustable upper camber arms provide a wider adjustment range, making it possible to run increased negative rear camber for:

• Fast-road geometry
• Trackday setups
• Clubsport builds
• Semi-slick tyres
• Slick tyres
• More aggressive rear alignment settings

This gives significantly more flexibility when setting up the rear axle.

Improved Cornering Grip & Stability

Increasing rear camber appropriately can help the tyre maintain a more effective contact patch during hard cornering.

Potential benefits include:

• Increased mid-corner grip
• Improved rear stability
• Better corner-exit traction
• More consistent rear axle behaviour
• Improved chassis balance

The final result depends on the complete geometry setup, tyre choice and intended use of the vehicle.

Better Use of Performance Tyres

Semi-slick and slick tyres can generate significantly higher cornering loads than conventional road tyres.

A wider camber adjustment range allows the rear geometry to be configured to make better use of that additional grip.

Suspension Secrets considers increased rear camber adjustment particularly important for cars running:

• Semi-slick tyres
• Slick tyres
• Track-focused suspension
• More aggressive chassis setups

Improved Tyre Wear Under Hard Driving

With insufficient negative camber, the outside shoulder of the rear tyre can become overloaded during hard cornering.

Correctly increasing rear camber can help distribute load more effectively across the tyre during performance driving, potentially reducing excessive outer-edge wear.

Road tyre wear still depends heavily on camber, toe and driving style, so a professional geometry setup is essential.

Improved Chassis Balance

Rear camber has a significant influence on how the rear axle behaves through a corner.

Increasing negative rear camber appropriately can help provide:

• Greater rear-end grip
• Improved mid-corner stability
• Better balance between the front and rear axles
• More confidence when applying throttle on corner exit

This makes the arms particularly useful as part of a complete road or track geometry setup.

Motorsport-Spec Fluro Bearings

Suspension Secrets uses motorsport-spec Fluro bearings within the arm assembly.

These provide a more precise connection than compliant factory-style rubber bushes and are selected for:

• Reduced unwanted flex
• Accurate suspension movement
• Improved geometry consistency
• High load capability
• Long-term performance

As with other spherical-bearing suspension components, some additional mechanical feedback may be noticeable compared with a fully rubber-mounted factory setup.

UK Designed & Manufactured

Suspension Secrets designs and manufactures these camber arms in the UK.

Construction includes:

• Billet 6082 T6 aircraft-grade aluminium
• Corrosion-resistant 316 stainless steel
• Motorsport-spec Fluro bearings

These materials are selected for strength, durability and corrosion resistance in demanding road and track applications.

Key Benefits

• Wider rear camber adjustment range
• Increased negative camber capability
• Improved cornering grip
• Increased rear-end stability
• Better mid-corner traction
• Improved corner-exit traction
• Improved chassis balance
• Potential reduction in excessive outer-edge tyre wear
• Better suitability for semi-slick and slick tyres
• Motorsport-spec Fluro bearings
• Billet 6082 T6 aluminium construction
• Corrosion-resistant 316 stainless-steel components
• Designed and manufactured in the UK

Ideal for Road & Track Geometry

These arms are particularly useful for BMW 1M models fitted with:

• Lowering springs
• Coilovers
• Increased rear camber
• Semi-slick tyres
• Slick tyres
• Track-focused geometry

They provide the additional adjustment required when the standard eccentric bolts no longer offer enough range.

Vehicle Fitment

Designed for:

• BMW E82 1M Coupe

If you are unsure whether these arms are suitable for your suspension or geometry setup, please contact The Rosso Corsa Collective before ordering.

Professional Installation & Geometry Setup Recommended

Professional installation is strongly recommended.

After fitting, the vehicle should receive a full four-wheel geometry setup so rear camber and toe can be configured correctly around the intended road or track use.

When increasing rear camber substantially, rear toe should also be checked carefully to ensure the overall rear axle geometry remains balanced.
