MMX Performance BMW 5x120 Wheel Spacer Kit - M14x1.25
The MMX Performance BMW 5x120 Wheel Spacer Kit (M14x1.25) is a precision-engineered upgrade designed to enhance both the stance and handling characteristics of BMW vehicles utilizing the 5x120 bolt pattern. By increasing track width, these spacers deliver improved stability, sharper turn-in response, and a more aggressive, flush wheel fitment without compromising safety or ride quality.
Manufactured from aerospace-grade 7075-T6 aluminum, each spacer is CNC-machined to exact tolerances, ensuring exceptional strength, durability, and minimal added weight. Compared to lower-grade materials, 7075-T6 aluminum provides superior load-bearing capacity while maintaining a lightweight profile, making it ideal for both street and performance applications.
The hubcentric design incorporates a precisely machined 72.6mm center bore and integrated spigot ring, allowing the spacer to seat perfectly on the vehicle hub. This ensures accurate wheel centering, eliminates vibration, and maintains OE-level balance even under high-speed or high-load conditions. The result is a stable, vibration-free driving experience that meets the demands of performance-focused BMW platforms.
By spacing the wheel outward from the hub, the MMX kit provides the additional clearance often required for upgraded brake systems, coilover suspension setups, or wider wheel and tire combinations. This allows for optimized fitment while achieving a visually balanced, factory-correct stance.
Each kit is supplied with high-strength M14x1.25 grade 10.9 carbon steel extended wheel bolts, finished in black for corrosion resistance and a clean OEM+ appearance. These longer bolts are specifically matched to spacer thickness and are essential for maintaining proper thread engagement and safe installation.
The spacers are finished in a durable black anodized coating, protecting against corrosion, road debris, and long-term environmental exposure. The rear mounting face features integrated relief cutouts to prevent bonding to the hub, ensuring easier removal after extended use.
