MAD BMW G90 G99 M5 Wheel Spacers | 10mm, 12mm, 15mm & 20mm
Sep 21st 2026
The BMW G90 M5 and G99 M5 Touring have an aggressive presence from the factory, but wheel fitment and stance can make an important difference in the overall appearance of the car. MAD Wheel Spacers provide a straightforward way to adjust wheel positioning while maintaining a purpose-built fit for the M5 platform.
Available in 10mm, 12mm, 15mm, and 20mm thicknesses, these spacers allow owners to choose the amount of additional spacing that best suits their setup.
Each spacer is hub centric and CNC machined from 7075-T6 aluminum, combining precise manufacturing with a lightweight, high-strength construction.
7075-T6 Aluminum Construction
MAD uses high-grade 7075-T6 aluminum for the spacers. The material is CNC machined to provide accurate dimensions and finished with a black anodized coating for added durability and a clean appearance behind the wheel.
The hub-centric design is engineered to properly locate the wheel on the vehicle's hub, while the precise construction helps maintain proper wheel positioning after installation.
Available in Four Thicknesses
Different wheel and tire combinations can call for different spacer thicknesses. MAD offers four options for the G90/G99 M5:
- 10mm
- 12mm
- 15mm
- 20mm
The spacers are sold as a set of two, so two sets are required to equip both the front and rear axles.
Choosing the appropriate thickness depends on the wheel, tire, suspension setup, and desired final fitment.
Extended Black Wheel Bolts Included
Installing wheel spacers requires longer wheel bolts to accommodate the additional thickness. MAD includes extended black wheel bolts with the spacer kit, eliminating the need to purchase the required hardware separately.
The included bolts also maintain a consistent appearance with the black anodized spacers and help make the installation a complete package.
Designed for Straightforward Installation
The MAD wheel spacers are designed as a simple bolt-on upgrade. Their hub-centric construction provides a precise fit at the wheel hub, while built-in pry tabs make removing the spacers easier when servicing or changing the vehicle's setup.
No additional spacer-specific hardware is required beyond the included extended wheel bolts.
As with any wheel spacer installation, proper torque procedures and verification of wheel-to-hub engagement should be followed during installation.
More Than Just a Visual Upgrade
Wheel spacers change the position of the wheels relative to the vehicle, allowing owners to achieve a wider-looking stance and a more flush appearance.
Depending on the chosen thickness and overall wheel setup, moving the wheels outward can also alter the vehicle's track width and steering or handling characteristics. For this reason, spacer thickness should be selected according to the specific wheel, tire, suspension, and clearance requirements of the vehicle.

Lifetime MAD Warranty
Like other MAD products, these wheel spacers are backed by a lifetime warranty against defects and fitment issues.
That coverage reflects MAD's focus on producing components that are designed specifically for their intended applications rather than relying on generic universal hardware.
