As long as you stick to quality ones and install them correctly, 12mm spacers are exactly safe to use. Always get wheel spacers from a genuine brand. Brand wheel spacers focus on quality and reputation. Decades of research and millions of dollars have gone into the advancement and development of wheel spacers.
They have drastically improved over the years and become safer and more reliable. Genuine brand 12mm spacers will not fail you. But with so many options out there, how do you know what types are the best option? Let’s dive into the world of 12mm spacers and find out what works best for your wheel fitment.
Top 5 Factors of Choosing the Best 12mm Spacers
Bolt Patterns:
When upgrading with wheel spacers, a vehicle-specific set is always the best option. Double-check the vehicle bolt pattern (PCD) in your owner’s manual before buying a set.
Wheel Offset:
It is a good idea to compare the difference from the desired offset to current offset. Giving an example, if you get a +50mm offset rim, then 12mm spacers change the offset to +38mm. The lower the offset is, the further the wheels are outwards from the hub assembly.
Longer Wheel Bolts:
Extended wheel bolts are necessary options if you use slip-on 12mm spacers. The general rule of thumb is that the thread length must be equal to or greater than the diameter of the bolt itself. Giving an example, an M14 wheel bolt would need at least 14mm threads to ensure a safe engagement.
Forged Aluminum:
A set of forged 12mm aluminum spacers are lightweight, strong, and good in corrosion resistance. Always choose genuine brand wheel spacers.
Hub-centric Types:
Hub-centric 12mm spacers can create a firm and stable wheel connection. If you often take your car to the track, hub-centric wheel spacers reduce the chance of high-speed vibration.
What is the 12mm Spacers Torque Spec?
The REFERENCE torque spec of the 12mm spacers is 103.5 ft-lb for M14 bolts and 83.3 ft-lb for M12 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.
