Looking to dial in the perfect stance on your G8X?

The factory fitment leaves room on the table — but a proper set of hub-centric spacers brings the wheels flush with the fenders and completely transforms the look.

The MAD Hub-Centric Wheel Spacers are precision CNC machined from high-grade 7075-T6 aluminum and designed to deliver a flush, aggressive stance while maintaining OEM-level fitment and safety.

Flush.
Aggressive.
OEM+ fitment.

Why these Spacers

Fitment is everything on the G8X platform.

A properly spec’d spacer setup pushes the wheels out to sit perfectly with the fender — eliminating the sunken factory look and giving the car a much wider, more planted presence.

On my own build, I run 15mm spacers all around, paired with the Automaz Fender Clearance pieces up front to ensure proper clearance with zero rubbing while maintaining the ideal stance.

These spacers are hub-centric, meaning they mount directly to the hub just like OEM wheels, ensuring proper alignment and vibration-free performance.

Built from 7075-T6 aluminum alloy and anodized black for durability and corrosion resistance, they’re designed to handle both daily driving and spirited use.
