MMX BMW G8x Front wheel arch clearance Kit (Set of 2 pcs)

MMX BMW G8X Front Wheel Arch Clearance Kit – Set of 2

Increase front wheel and tyre clearance on your modified BMW G8X M car with the MMX Front Wheel Arch Clearance Kit.

Designed for the BMW G87 M2, G80/G81 M3 and G82/G83 M4, this kit replaces the restrictive vented section of the factory front arch liner with a slimmer aluminium grille, creating additional clearance for lowered suspension, wider tyres and wheel spacer setups.

The result is a simple, functional solution that helps prevent tyre contact with the original plastic vent fins while still maintaining airflow through the front bumper area and helping protect against road debris.

Why Fit the MMX Front Wheel Arch Clearance Kit?

The factory BMW G8X front arch liner includes a vented plastic section designed to allow air to escape from the front bumper.

On a standard-height car with factory wheels and tyres, clearance is generally sufficient.

Once the vehicle is modified with:

• Lowering springs
• Height-adjustable springs
• Coilovers
• Wider tyres
• Wider wheels
• Wheel spacers
• More aggressive alignment

the gap between the tyre and the factory vent section can become significantly smaller.

Under steering lock or suspension compression, the tyre may begin to contact the plastic fins.

MMX developed this replacement grille kit specifically to create more usable space in this area.

More Clearance for Lowered G8X Cars

Lowering the vehicle reduces the available space between the tyre and surrounding arch-liner components.

This becomes particularly relevant on G8X M cars running:

• MMX lowering springs
• MMX Height Adjustable Spring Kits
• KW HAS kits
• Coilovers
• Aggressive track ride heights

The MMX clearance kit removes the bulky original vented plastic section and replaces it with a flatter aluminium grille.

This creates additional space where the tyre is most likely to make contact.

Ideal for Wider Tyres

BMW G8X owners often increase tyre width as part of a performance or track-focused setup.

A wider tyre can provide:

• Increased mechanical grip
• Improved braking traction
• Greater cornering performance
• Better use of wider aftermarket wheels

However, increasing tyre width also reduces clearance inside the wheel arch.

The MMX Front Wheel Arch Clearance Kit helps recover some of that lost space by replacing one of the more restrictive factory liner sections.

Useful with Wheel Spacers

Wheel spacers move the wheel outward relative to the hub.

Although this can improve stance and help achieve a desired wheel fitment, it can also change the path the tyre follows through the wheel arch during steering.

MMX specifically developed the clearance kit with modified setups such as wheel spacers in mind.

For cars combining lowering, larger tyres and spacers, the additional clearance can become particularly useful.

Helps Prevent Tyre Contact

If the tyre catches the original plastic vent fins, the fins can become damaged or broken.

MMX notes that damaged pieces may also create a risk of contact with the tyre or surrounding components such as the radiator area.

Replacing the original vent section with the MMX aluminium grille removes the protruding plastic fins and creates a cleaner, flatter surface.

Maintains Front Bumper Airflow

The factory vented arch section is not simply decorative.

It allows air to escape from the front bumper area.

Rather than blocking this opening, the MMX replacement uses a laser-cut grille design that continues to allow airflow through the arch liner.

This means the increased clearance does not come at the expense of completely sealing the original vent path.

Helps Protect Against Debris

The open hexagonal grille structure allows airflow while still creating a barrier between the wheel arch and the front bumper cavity.

This helps reduce the chance of larger debris passing directly through the opening.

For track and road cars alike, maintaining this balance between airflow and protection is important.

Aluminium Construction

The MMX grilles are manufactured from lightweight aluminium.

This provides:

• Low weight
• Good durability
• Resistance to deformation
• A thinner profile than the original plastic vent section
• Suitable strength for wheel-arch use

Aluminium construction also allows the grille to provide the additional clearance required without introducing unnecessary bulk.

Black Powder-Coated Finish

Each grille is finished in a durable black powder coating.

This gives the component a discreet OEM-style appearance once installed and helps protect the aluminium surface from:

• Road grime
• Moisture
• General underbody contamination
• Stone and debris exposure

The black finish helps the grille blend naturally into the existing wheel arch liner.

Laser-Cut Hexagonal Design

The MMX kit uses a laser-cut hexagonal grille pattern.

This provides a clean finish while maintaining an open area for airflow.

The design also gives the component a more purposeful motorsport-style appearance without making it overly visible once installed.

Secure Four-Point Mounting

Each grille is secured using four fixings per side.

This provides a stable attachment to the remaining factory arch liner.

All required MMX installation fixtures and fittings are supplied with the kit.

Important – Cutting Is Required

Installation requires modification of the original front wheel arch liner.

The factory vented section must be cut out and removed before the MMX grille can be installed.

This means the upgrade is not completely reversible without replacing the original arch liner.

For this reason, installation should be planned carefully before cutting.

Professional Installation Recommended

Although the kit itself is relatively straightforward, accurate cutting of the original arch liner is important.

Professional installation is recommended if you are not comfortable modifying body trim or wheel arch components.

Correct installation should include:

• Removing or accessing the front arch liner
• Marking the original vent section
• Carefully cutting the factory liner
• Removing the vented section
• Positioning the MMX grille
• Installing the supplied fixings
• Checking tyre clearance at full steering lock
• Checking clearance through suspension travel

Ideal for Track & Fast-Road G8X Builds

The MMX Front Wheel Arch Clearance Kit is particularly useful for:

• Lowered G87 M2 builds
• Lowered G80/G81 M3 models
• Lowered G82/G83 M4 models
• Cars on height-adjustable spring kits
• Coilover-equipped cars
• Cars running wider front tyres
• Cars using wheel spacers
• Track-day vehicles
• Aggressive fast-road setups

For heavily modified front wheel and suspension setups, every additional millimetre of usable clearance can help.

Works Well with MMX Suspension Upgrades

The clearance kit makes a natural supporting upgrade alongside MMX suspension products such as:

• MMX Lowering Springs
• MMX Height Adjustable Lowering Springs
• MMX Adjustable Front Droplinks
• MMX suspension bush upgrades

When ride height and wheel fitment become more aggressive, addressing wheel-arch clearance at the same time can help prevent rubbing issues later.

Wheel Clearance Considerations

The MMX kit creates additional clearance at the factory vent section, but it does not guarantee that every wheel and tyre combination will fit.

Overall clearance still depends on:

• Wheel width
• Wheel offset
• Tyre width
• Tyre profile
• Spacer thickness
• Ride height
• Camber
• Steering lock
• Suspension travel

Cars with aggressive fitments should still be checked carefully after installation.

BMW G87 M2

The G87 M2 is included in MMX's official application list.

The kit is particularly useful on G87 builds running wider front tyres, wheel spacers or reduced ride height, where the factory arch-liner vent can become a clearance limitation.

BMW G80 / G81 M3

The kit is also compatible with the BMW G80 M3 and G81 M3 Touring.

Both platforms are commonly modified with wider wheel and tyre combinations, making increased inner arch clearance especially useful on performance-focused setups.

BMW G82 / G83 M4

The BMW G82 M4 Coupe and G83 M4 Convertible are also supported.

The same factory wheel-arch vent design can become restrictive once the car is lowered or fitted with more aggressive front wheel setups.

Compatibility

Designed for applicable BMW G8X M cars including:

• BMW G87 M2 – 2023+
• BMW G80 M3 – 2021+
• BMW G81 M3 Touring – 2021+
• BMW G82 M4 – 2021+
