This time, BONOSS wheel spacer engineers got to test out the BMW 3 Series. Here are the wheel spacer sizes of this car:
– **Model**: BMW 3 Series
– **Special note**: Fitted with aftermarket shock springs
– **Flush wheel spacer size**: front 12mm / rear 15mm
– **Bolt pattern (PCD)**: 5x112mm
– **Center bore (CB)**: 66.5mm
– **Wheel bolt size**: M14x1.25mm
If you are an owner of the BMW 3 Series and planning to buy the best forged wheel spacers, don’t hesitate. BONOSS company has got you covered.
High-end wheel spacers are produced with top-quality materials to provide optimum performance to the vehicle. For example, BONOSS forged lightweight plus wheel spacers are made of advanced machinery and undergo a series of safety tests before leaving the factory. BONOSS offers several key advantages that make their wheel spacers a top choice.
## 1. Effective Lightweight Plus for Better Performance
**BONOSS forged lightweight plus wheel spacers are hollowed for an extra lightweight advantage. The hollowed hole is a proven design that effectively reduces weight. The average weight of each BONOSS forged lightweight plus spacer is more than 20% lighter than the previous-gen product. Adding such a small lightweight component wouldn’t noticeably affect the acceleration.
## 2. Optimized Hub-centric for Zero Vibration
**BONOSS forged lightweight plus wheel spacers come with multi-stage hub-centric rings. The hub-centric metal ring is machined with multiple layers, and the bevels fit the corresponding hub flange, which eliminates any possible gaps. This reduces the chances of vibrations.
## 3. Hard Anodizing for Improved Durability
**Since BONOSS forged lightweight plus wheel spacers are made of aluminum alloy, they won’t rust easily. What’s better, BONOSS applies a special hard anodized surface treatment to further resist rust and corrosion. Anodizing creates a perfectly formed to ensure the spacer surface of unparalleled corrosion resistance.

**Q: Do I need longer wheel bolts for wheel spacers?**
A: For a proper installation, you need longer wheel bolts for 3mm to 20mm slip-on wheel spacers.
**Q: Will wheel spacers rust?**
A: Quality 16mm spacers won’t rust so easily. Aluminum spacers are a popular choice for automobiles, not only because they’re lightweight but also because they resist corrosion.
**Q: What is the torque for wheel spacers?**
A: The REFERENCE torque specs for wheel spacers should be 83.3 ft-lbs for M12 bolts and 103.5 ft-lbs for M14 bolts. It is highly recommended to consult a tire expert before operating.
