The BMW Wheel Spacers Adapter is a highly cost-effective solution for improving vehicle track and appearance. Specifically designed for BMW models, J&W Auto Part has developed precision gaskets compatible with different chassis codes.
Based on thickness requirements, our products are divided into two core structures:
Extended Bolts Type: Suitable for thicknesses less than 20mm.
Insert Nuts Type: Suitable for thicknesses exceeding 20mm, utilizing a high-strength 18mm high nut to ensure installation safety.

1. Top-Tier Manufacturing Process
We employ 800-ton forging technology, rather than ordinary casting. This high-pressure forming process ensures the density of the internal structure of the BMW Wheel Spacers Adapter, significantly improving fatigue resistance and effectively preventing cracking under extreme driving conditions.
2. Stringent Precision Control
Through 40 advanced CNC machining centers, we control errors to the micron level. This ensures a perfect fit between the gasket and the BMW axle center bore, eliminating vibration issues during high-speed driving.
3. Diverse Customization Services (ODM/OEM)
Drawing-Based Manufacturing: We can precisely produce according to your provided drawings.
Material Switching: We offer cost-effective 6061 material and high-performance 7075 material.
Full Supply Chain Support: We have our own automated electroplating line to ensure that the corrosion resistance of bolts and gaskets meets industry standards.
Production Capabilities and Brand Advantages
J&W Auto Parts factory is located in Ningbo, Zhejiang Province, covering an area of over 10 acres and employing more than 100 experienced technicians.
Advanced Equipment: Equipped with 12 large cold heading machines, 2 large stamping presses, and a comprehensive 5S management system.
Rich Product Line: In addition to BMW Wheel Spacers Adapters, we also produce matching high-strength wheel lug bolts and nuts.
Efficient Delivery: Optimized production processes significantly improve work efficiency, ensuring on-time order delivery.
Q1: How do I determine which thread specification should I choose for my BMW?
BMW thread specifications vary depending on the model year. Generally, older models (such as E chassis) use M12x1.5, while newer models (such as F and G chassis) use M14x1.25. Before purchasing a BMW Wheel Spacers Adapter, please be sure to confirm the original vehicle bolt parameters.
Q2: Why is it not recommended to use embedded nut type for bolts under 20mm?
Because the height of a high-strength embedded nut is approximately 18mm. If the washer thickness is only 10mm or 15mm, the washer body cannot completely cover the nut, which will cause structural interference. Therefore, thin washers must be used with extended bolts.
Q3: What is the difference between forged and cast washers?
The forging process changes the metal's crystal structure under high pressure, making it stronger. For load-bearing components like the BMW Wheel Spacers Adapter, forged products have better impact resistance and safety.
