Using 12 mm spacers is a good practical application for aesthetic purposes and performance upgrades. It is the most cost effective and easiest way to widen wheel track. This is a big improvement for your ride. For example, the wheels sit further away which provides better stability and rollover resistance. In addition, wheel spacers add more inner wheel clearance.
This allows you to install bigger tires and larger brakes safely and nicely. For those who plan on keeping the factory wheels and want to add bigger brake calipers, the wheel spacers will be a very useful solution. However, getting the wrong wheel spacers can cause improper installation. To avoid costly mistakes, here are 7 must-know tips of the best 12 mm spacers.
7 Pro Tips for the Best 12 mm Spacers
- Thickness:
Think about your goal. If you just need a little bit of wheel clearance to fit a big brake kit, a thin thickness like 12mm is a good idea. If you plan to achieve a more aggressive wheel style, thicker spacers like 25mm may be a better option. - Proper Offset:
The 12 mm spacers essentially reduce the distance from the wheel center to the hub assembly, thus they subtract the offset. For example: if the stock wheel offset is +42mm, then a 12mm spacer will make the final offset +30mm. Use an offset calculator before making a decision. - Bolt Pattern:
Wheel spacers are installed on the hub assembly and in return attach the wheels to them. In this case, the bolt pattern is an important factor. If you use 12 mm spacers with stock wheels, make sure the bolt pattern is the same as the OEM one. - Hub-centric:
Hub-centric spacers come with specific center rings that allow the spacers to sit centered on your hub, rather than dangling off the bolts. They provide a firm and stable wheel connection, meaning no additional force, no vibration, and no annoying noise. - Wheel Bolts:
If you use 12mm spacers, you need longer wheel bolts to secure rim spacers safely. Stock bolt length + spacer thickness = required wheel bolt length. - Quality Material:
The best 12 mm spacers should be crafted from forged 7075-T6 aluminum alloys which offer superior strength and rust resistance. - SGS TÜV Test Reports:
Good 12 mm wheel spacers should come with proper SGS TÜV performance test reports. SGS TÜV test reports = guaranteed quality and performance.
