Choose between BMS Classic and Lightweight BMW wheel spacer kits for a wider stance, improved wheel fitment, and a more aggressive appearance.
Burger Motorsports wheel spacers are precision-engineered for compatible BMW G, U, I, and select F chassis vehicles using a 5x112 bolt pattern and 66.6mm center bore. Each spacer is CNC-machined from high-strength 7075-T6 aluminum, finished in durable black anodizing, and designed to provide a precise hub-centric fit.
BMS BMW wheel spacers move the wheels and tires outward to help fill the wheel wells, improve the vehicle’s stance, increase lateral stability, and provide additional clearance for certain aftermarket wheels, suspension components, and larger brake systems. Select the Classic kit for our proven original design or the Lightweight kit for reduced rotating mass and upgraded 12.9-grade concentric floating-seat lug bolts.
Choose Your BMS BMW Wheel Spacer Style
Classic BMW Wheel Spacer Kit
The BMS Classic Wheel Spacer Kit is our proven original BMW wheel spacer design and the best-value option for street-driven and performance BMW vehicles. It provides the same high-strength 7075-T6 aluminum construction, black anodized finish, precise hub-centric fitment, and aggressive appearance that BMS wheel spacers are known for.
Each Classic spacer kit includes ten extended zinc-coated 10.9-grade cone-seat lug bolts properly sized for the selected spacer width. The Classic kit is ideal for customers who want a strong, dependable, and cost-effective BMW wheel spacer package without the additional weight-reduction features and floating-seat bolts included with the Lightweight version.
Classic spacer widths:
- 10mm
- 13mm
- 15mm
Lightweight BMW Wheel Spacer Kit
The BMS Lightweight Wheel Spacer Kit is a performance-oriented version of our popular BMW G and U chassis wheel spacers. It is designed for enthusiasts who want to reduce unnecessary rotating mass while maintaining the strength, precise fitment, and durability required for demanding street and track use.
Lightweight BMS BMW wheel spacers feature a precision hub-centric design and include upgraded zinc-coated 12.9-grade Motorsport steel lug bolts. Each bolt uses a concentric floating-seat washer that provides a secure mating surface against the wheel, helps maintain proper clamping force, and reduces wheel-seat chafing during installation and removal.
The Lightweight kit is the premium choice for BMW owners who prioritize weight reduction, high-performance hardware, and a wider selection of spacer widths.
Lightweight spacer widths:
- 10mm
- 13mm
- 15mm
- 18mm
- 20mm
Benefits of BMS BMW Wheel Spacers
BMW wheel spacers are one of the easiest bolt-on upgrades for improving the appearance, stance, and wheel fitment of your vehicle. By moving the wheels outward, properly selected BMS wheel spacers can provide:
- A wider and more aggressive BMW stance
- Improved wheel-well fitment
- Increased lateral stability
- Additional clearance for certain suspension components
- Additional clearance for certain larger brake systems
- Improved fitment for aftermarket wheels and different offsets
- A less recessed appearance with factory or winter wheels
Both Classic and Lightweight BMS wheel spacers are suitable for compatible rear-wheel-drive and xDrive BMW vehicles when correctly sized, properly installed, and used with the supplied extended lug bolts.
Precision Hub-Centric BMW Fitment
BMS wheel spacers are hub-centric. The spacer’s 66.6mm center bore matches the compatible factory BMW hub, while the outer hub lip centers the wheel using the same basic arrangement as the original wheel hub.
This precision-machined design properly centers the wheel and helps provide smooth, vibration-free operation when the hub, spacer, and wheel mounting surfaces are clean and the spacer is installed correctly.
Strong 7075-T6 Aluminum Construction
Both BMS Classic and Lightweight BMW wheel spacers are CNC-machined from high-strength 7075-T6 aluminum alloy. This premium aluminum provides an excellent combination of strength, durability, and low weight for demanding street and performance applications.
Each spacer is finished with durable black anodizing for corrosion resistance and a clean appearance that complements factory and aftermarket BMW wheels.
What Width BMW Wheel Spacer Should I Choose?
Most compatible BMW G chassis vehicles using factory wheels and factory tire sizes commonly use 10mm to 13mm wheel spacers in the front and 13mm to 15mm wheel spacers in the rear.
The 18mm and 20mm Lightweight wheel spacers are intended for applications with additional wheel-well clearance or specific wheel, tire, and offset combinations. A 20mm spacer should only be used on applications with sufficient clearance.
Always measure before ordering. The correct BMW wheel spacer width depends on the vehicle, wheel width, wheel offset, tire size, suspension height, alignment settings, brake configuration, and available fender clearance. Photos and general sizing recommendations are for reference because vehicles with the same chassis can require different spacer widths.
Simple Bolt-On BMW Wheel Spacer Installation
Installation is straightforward. Remove the wheel, thoroughly clean the factory hub and wheel mounting surfaces, apply a light coating of the included anti-seize to the appropriate hub surface, place the spacer completely against the hub, reinstall the wheel, and secure it using the extended lug bolts supplied with the selected kit.
Each set of extended lug bolts is properly sized for its corresponding spacer width. The supplied bolts are approximately the spacer thickness longer than the factory wheel bolts and must not be mixed between different spacer sizes.
Each kit contains two wheel spacers for one axle. Two kits are required to install wheel spacers on all four wheels.
