Introducing MBS Lightweight BMW Wheel Spacers – Designed for Performance and Style

Take your G chassis BMW to the next level with the all-new Lightweight Wheel Spacers from MBS. Engineered for enthusiasts, these spacers are the perfect blend of form and function—enhancing both the appearance and handling of your vehicle.

This is the lightweight racing version of our popular G chassis BMW spacers, now featuring our upgraded floating seat washer lug bolts for improved performance and durability.

Why choose MBS spacers?
Our precision-engineered, hub-centric design ensures a perfect fit, while the innovative concentric floating seat lug bolts provide optimal alignment and load distribution. Built from high-grade materials and developed with over a decade of spacer design and manufacturing experience, MBS delivers uncompromising quality and performance—on the street or the track.

Whether you're dialing in the perfect stance, enhancing cornering stability, or just upgrading the aggressive look of your BMW, MBS Wheel Spacers deliver outstanding results across the board.

Benefits of MBS Wheel Spacers:

• Instantly push your wheels outward for a wider, more aggressive look

• Improve lateral stability and handling

• Create clearance for aftermarket suspension, big brake kits, or custom offsets

• Enhance aesthetics without breaking the bank

• Fill in the wheel well for a flush, performance-inspired appearance

Each set is custom designed by MBS specifically for BMW applications to ensure a vibration-free, secure fit. Includes a packet of anti-seize grease to apply to the factory hub for easy removal in the future.

Upgrade your BMW with MBS Wheel Spacers—where precision meets performance.

Premium Build & Quality
Each MBS wheel spacer is precision CNC-machined from high-grade 7075-T6 aluminum alloy and anodized in black for enhanced durability and corrosion resistance. Our spacers are sold in pairs (2 pieces) and include 10 extended concentric swivel washer lug bolts that meet and exceed OE specifications. To outfit an entire vehicle, two spacer kits are required. All MBS wheel spacers are hub-centric and fully compatible with xDrive (all-wheel drive) BMW models.

Hub-Centric Design
MBS spacers are engineered to match your factory BMW hub bore precisely, ensuring a snug, vibration-free fit. The integrated factory-style hub extension perfectly aligns with your wheel’s center bore for improved balance and ride quality.

Concentric Floating Seat Lug Bolts
Our lug bolts are crafted from 12.9 motorsport-grade steel for maximum strength and safety, then zinc-plated for long-lasting corrosion resistance. Each bolt features a concentric floating seat washer that ensures a secure mating surface, helps maintain proper torque, and reduces wear during installation and removal.
