MMX 12mm Hubcentric Wheel Spacers – BMW G-Series & MINI F-Series

Improve the stance, wheel fitment and handling of your BMW G-Series or MINI F-Series with the MMX 12mm Hubcentric Wheel Spacer and Bolt Kit.

Precision-machined from lightweight 7075-T6 aluminium, the MMX spacers move each wheel 12mm further outward from the hub, creating a wider track and helping the wheels sit more flush with the bodywork.

The hubcentric design incorporates a precision-machined locating lip that maintains the correct 66.5mm centre bore, helping the wheel remain accurately centred on the hub and reducing the risk of vibration caused by poor alignment.

Suitable for BMW G-Series models and MINI F54, F55, F56, F57 and F60 applications using the 5x112 bolt pattern, each pair is supplied with ten extended Grade 10.9 black wheel bolts for correct installation.

Why Fit 12mm Wheel Spacers?

Wheel spacers are one of the simplest ways to improve the stance of a vehicle without replacing the wheels.

By positioning the wheels further outward, the MMX 12mm spacers can help:

• Reduce the recessed factory wheel appearance
• Create a wider and more purposeful stance
• Position the wheel more flush with the arch
• Increase track width
• Improve clearance around suspension or brake components
• Complement lowered suspension
• Improve overall wheel fitment

For many BMW and MINI applications, 12mm provides a noticeable improvement without creating an excessively aggressive stance.

12mm Wider Per Wheel

Each spacer moves the corresponding wheel 12mm outward from the hub.

When fitted to both wheels on one axle, this increases the overall track width by approximately 24mm.

This creates a noticeably broader stance while retaining a relatively subtle OEM-plus appearance.

Improved Wheel Fitment

Factory wheel fitment often positions the wheels further inside the arches than some owners prefer.

The MMX spacers effectively alter the wheel offset by moving the wheel outward.

For example, fitting a 12mm spacer has the same positional effect as reducing the wheel offset by 12mm.

This can help create a more flush wheel-to-arch relationship without requiring replacement wheels.

Wider, More Purposeful Stance

One of the primary reasons to fit spacers is appearance.

Moving the wheels outward can substantially change the way the car sits visually.

The MMX 12mm spacers are particularly well suited to:

• Standard-height cars
• Lowered vehicles
• Cars with factory wheels
• Aftermarket wheel setups
• Performance-focused builds

They can help remove the visually narrow appearance created when the factory wheels sit deep within the arches.

Hubcentric Design

Correct wheel location is extremely important when fitting spacers.

MMX uses a hubcentric design with a precision-machined alloy spigot.

Rather than relying solely on the wheel bolts to centre the wheel, the spacer maintains the correct hub-centred location.

This helps provide:

• Accurate wheel alignment
• Correct centring on the hub
• Reduced risk of vibration
• Easier wheel installation
• More consistent fitment

MMX maintains the OE 66.5mm centre bore for compatible BMW G-Series and MINI F-Series applications.

5x112 Bolt Pattern

These spacers use the 5x112 PCD found across compatible modern BMW G-Series and F-Series MINI applications.

This means the spacer has:

• 5 wheel bolt positions
• 112mm pitch circle diameter

The spacer must always match the vehicle's original hub specification.

7075-T6 Aluminium Construction

MMX manufactures the spacers from aerospace-grade 7075-T6 aluminium.

This high-strength aluminium alloy provides an excellent combination of:

• Low weight
• High strength
• Dimensional stability
• Durability

The lightweight construction minimises additional unsprung and rotational mass while providing the strength required for a wheel-mounting component.

Extended Wheel Bolts Included

A spacer increases the distance between the wheel and hub, meaning the original wheel bolts are no longer long enough to provide the required thread engagement.

MMX therefore supplies ten extended black wheel bolts with each pair of spacers.

The bolts use Grade 10.9 carbon-steel construction for high strength.

Using the correctly sized extended hardware is essential when installing wheel spacers.

Sold as a Pair

The MMX 12mm spacer kit is supplied as a pair for one axle.

Each kit therefore includes:

• 2x 12mm wheel spacers
• 10x extended wheel bolts

To space both the front and rear axles, two pairs are required.

Mix Spacer Widths Front & Rear

MMX also offers its hubcentric spacers in multiple widths.

This means different spacer thicknesses can be used on the front and rear axles to achieve the desired stance.

For example, depending on wheel fitment and available clearance, an owner may choose:

• 12mm front / 12mm rear
• 12mm front / 15mm rear
• 15mm front / 18mm rear

The correct combination depends on the vehicle, wheels, tyres, suspension and desired appearance.

Additional Brake Clearance

Moving the wheel outward can also provide additional inner clearance.

This may be useful when fitting:

• Larger brake calipers
• Big brake kits
• Different wheel designs
• Performance brake upgrades

However, spacer fitment does not guarantee clearance with every brake and wheel combination.

The setup should always be checked before use.

Additional Coilover Clearance

Aftermarket coilovers and wider wheels can sometimes reduce clearance between the inner wheel barrel or tyre and suspension components.

A wheel spacer moves the complete wheel assembly outward and can therefore provide additional clearance from:

• Coilover spring platforms
• Dampers
• Suspension arms
• Other inner-wheel components

Clearance should always be checked throughout the full steering and suspension range.

Ideal with Lowering Springs

Wheel spacers are especially popular on lowered vehicles.

Lowering springs reduce the wheel arch gap vertically, while spacers improve the lateral wheel position.

Combining the two can create a much more complete stance improvement.

They work particularly well alongside upgrades such as:

• MMX Lowering Springs
• Height-adjustable spring kits
• Sport dampers
• Coilovers

Handling Benefits

Moving the wheels outward increases the vehicle's track width.

A wider track can influence the way the chassis responds during cornering and may provide a broader, more planted feel.

However, spacer selection should primarily be based around correct wheel fitment, tyre clearance and suspension geometry rather than treating the spacer as a major standalone handling modification.

Important Fitment Checks

Before installation, ensure that:

• The spacer sits completely flat against the hub
• The wheel sits completely flat against the spacer
• The hubcentric lip correctly locates the wheel
• The correct extended bolts are used
• The wheel clears the arch
• The tyre clears suspension components
• Full steering lock remains unobstructed
• Adequate clearance remains through suspension travel

MMX specifically recommends checking arch clearance at full left and right steering lock after installation.

Wheel Bolt Torque

Wheel bolts should always be tightened to the vehicle manufacturer's specified torque using a calibrated torque wrench.

Wheel bolt torque should also be rechecked after the wheels have been removed or spacers installed.

Spacer Care

MMX advises against using aggressive acidic or alkaline wheel cleaners on the anodised spacer finish.

For cleaning, use:

• Water
• Mild soap
• pH-neutral products

Avoid aggressive wheel cleaners, solvents, abrasive compounds and strong traffic-film removers, as these can damage the spacer finish.
