They are designed to change wheel bolt pattern in order to properly install your aftermarket wheels.
As the BMW conversion wheel spacers increase the track width, you can handle the pickup trucks better. With so many options available, what size wheel adapters are best? In this post, we will explore the safe sizes, specific bolt pattern (PCD), and explain the offsets. Hope this guide sets you on the path to selecting the best BMW 5×120 to 5×114.3 adapters.
Choose the Right BMW 5×120 to 5×114.3 Adapters
It’s essential to note that not all BMW wheel adapters are created equal, and safety depends on several key factors:
Thickness:
As long as you install them proper, high-quality 20mm to 50mm adapters are safe to use. Here are the pros and cons of each size:
- 20mm: Starts to deliver noticeable stance changes and improved stability.
- 30mm: Offers a noticeable stance difference and enhances ride quality.
- 40mm: Makes your BMW car look more powerful and boosts the handling.
- 50mm: Allows you to fit a wide-body kit while keeping the stock wheels.
Bolt Pattern (PCD):
To ensure a safe fit, the adapter bolt pattern must be the same as the vehicle lug pattern. Double-check the vehicle bolt pattern in your owner’s manual before buying a set. For example,
- BMW 3 Series (E46): PCD=5x120mm, CB=72.5mm, Thread=M12x1.5mm.
- BMW 5 Series (E60): PCD=5x120mm, CB=72.5mm, Thread=M12x1.5mm.
- BMW X5 (E70): PCD=5x120mm, CB=74.1mm, Thread=M14x1.25mm.
Correct Offset:
Wheel adapters reduce the offset. Example: If your stock BMW wheel offset is +43mm, then a 20mm adapter will make the final offset +23mm.
What Are BMW 5×120 to 5×114.3 Adapters Torque Specs?
Installing 5×120 to 5×114.3 adapters on a BMW car is not a difficult task, but it requires precision. Use a torque wrench to tighten the lug bolts to the specified torque values. The REFERENCE torque spec on the 5×120 to 5×114.3 adapters is 83.3 lb-ft to 103.5 lb-ft. It’s best to consult a tire specialist to ensure the exact torque spec before operating.

Here are several key advantages that make BONOSS adapters a top choice.
1. Active Cooling, More Beneficial
Better than other hub adapters, BONOSS forged active cooling 5×120 to 5×114.3 adapters come with active cooling grooves which allow the external cold air to flow continuously inside the wheel adapter when it rotates.
In this case, BONOSS forged active cooling 5×120 to 5×114.3 wheel adapters send air into the rotors. The air takes away the heat, actively dissipating heat for the braking system. These BONOSS wheel adapters are helpful to reduce brake thermal decay and improve road safety.
2. Top-quality Aluminum, Stronger
BONOSS forged active cooling BMW 5×120 to 5×114.3 adapters are made of forged 6061-T6/ 7075-T6 aluminum alloy. After BONOSS’s unique super forging process, these aluminum wheel adapters provide stronger impact resistance, less fatigue strength, and better corrosion resistance. The ultimate tensile strength results of these two aluminum alloys are:
- Forged 6061-T6 adapters: 42000-45000 psi (300-310 MPa);
- Forged 7075-T6 adapters: 74000-78000 psi (510-572 MPa).
3. ISO Grade 12.9 Wheel Bolts, Safer
BONOSS forged active cooling 5×120 to 5×114.3 wheel adapters come with ISO 12.9 wheel bolts (tensile strength≥1220 MPa) and ISO grade 10 wheel nuts (proof load≥1,100 MPa). This hardware is meticulously coated with Dacromet. Such BONOSS forged wheel bolts and lug nuts give neutral salt spray resistances exceeding 500 hours.
Final Verdict: Choose BONOSS, Choose Safety and Performance
With these outstanding advantages, it’s clear that BONOSS forged BMW 5×120 to 5×114.3 wheel adapters offer exceptional safety, durability, and professionalism.
