MBS G-Series Wheel Spacers - G1X G2X G3X G4X G8X

MBS BMW Wheel Spacers 

Looking for a simple upgrade that transforms both the stance and performance of your BMW? MBS wheel spacers are a smart, affordable way to widen your vehicle’s track for improved handling and a bolder appearance. By pushing your wheels outward, these spacers give your BMW a more aggressive, planted look while enhancing cornering stability and responsiveness.

Whether you're making room for aftermarket suspension, dialing in the perfect offset, fitting larger brake kits, or simply correcting the sunken appearance of winter wheels, MBS spacers offer a clean, purposeful solution. Each set is tailor-made to fit BMW hubs precisely, ensuring a secure, vibration-free installation. We also include a packet of anti-seize grease to make future removal hassle-free.

Precision Engineering & Durable Build

Crafted from aerospace-grade 7075-T6 aluminum and finished in sleek black anodizing, MBS spacers are built to last. Each pair comes with 10 extended-length lug bolts that meet or exceed OEM specifications. Want a full-vehicle setup? Just grab two kits.

These spacers are fully hub-centric, meaning the center bore aligns perfectly with your factory hub and wheels—providing a factory-level fit with zero compromise on safety or smoothness. MBS spacers are fully compatible with both rear-wheel and all-wheel-drive BMWs, including xDrive models.

Choosing the Right Size

For most G-chassis BMWs running stock wheels and tires, we recommend:

• Front: 10mm to 13mm

• Rear: 13mm to 15mm

This setup typically balances aesthetics and function, helping you achieve the flush, aggressive stance BMW owners love.
