Installing 12 mm spacers will be helpful in wheel upgrades. If you get a set of alloy wheels that don’t quite fit your car because of high offset, wheel spacers will make the offset lower. By pushing the wheel further away from the hub assembly, they avoid potential rubbing issues. Normally, a big brake kit require more space between the wheels and the hub assembly.
By creating more inner wheel clearance, the 12 mm spacers clear big brake clearance issues effectively. Besides, they also make your car look sporty and muscular. You can achieve such a purpose without replacing the stock wheels. But the big question is: what are the best 12mm wheel spacers? Let’s dive in to help you make a wise decision.

How to Choose the Right 12 mm Spacers?
1. Quality Material:
The best 12mm spacers are made of high-strength materials like forged 7075-T6 aluminum alloys. These materials offer superior strength and resistance to the harsh conditions encountered during passionate driving.
2. Extended Wheel Bolts:
High-strength extended wheel bolts are necessary if you add 12mm wheel spacers. For example, if the OEM bolt length is 35mm, then you need 47mm wheel bolts to safely secure a half inch wheel spacer.
3. Hub-centric Design:
Hub-centric spacers can create a firm and stable wheel connection. If you often take your car to the track or off-roading adventures, you will eventually need wheel spacers with integrated hub-centric rings to ensure safety.
What is the 12 mm Spacers Torque Spec?
The REFERENCE torque spec of the 12mm wheel spacers is 83.3 ft-lb for M12 bolts and 103.5 ft-lb for M14 bolts. This is just a reference value. Some wheels or applications may require more or less tightening torque. It is always a good idea to ask a tire expert to figure out the exact torque spec before operating.

Who Sells the Best 12 mm Spacers?
With over 17 years of manufacturing experience and 1800+ drawing updates, BONOSS provides the best 12 mm wheel spacers. There are several key advantages that make their spacers a top choice.
1. Extreme Lightweight Benefits
As we all know, the lighter the unsprung weight is, the better the handling capabilities. BONOSS forged lightweight plus 12 mm spacers are machined with “Hollow Carved” holes. Compared with the previous production, they are at least 20% lighter. The weight of these BONOSS wheel spacers is quite insignificant, and they won’t damage any suspension parts.
2. Excellent Anti-corrosion Materials
BONOSS forged lightweight plus 12 mm spacers are made of high-strength 6061-T6 and 7075-T6 aluminum alloy materials. These wheel spacers have better thermal conductivity than steel ones. They are much lighter and much better in corrosion resistance.
To further prevent corrosion in wheel spacers, BONOSS applies a black hard anodizing surface treatment. It is ideally suited for aluminum to improve corrosion resistance. This process makes BONOSS forged lightweight plus 12 mm spacers more durable and corrosion-resistant.
3. Worry-free 10-year Warranty
Every genuine BONOSS forged lightweight plus 12 mm wheel spacer is covered by a 10-year warranty. This 10-year warranty protects the customer’s interest and ensures product quality and safety. It is worry-free to use BONOSS forged 12 mm spacers.
