The recommended torque spec of Mazda 3 wheel spacers would be mentioned in the manufacturer`s manual. Getting the best spacers properly installed is beneficial.

What Are Quality Mazda 3 Wheel Spacers Made Of?

When choosing quality spacers for performance upgrades, aluminum types come as a priority. BONOSS forged active cooling Mazda 3 rim spacers are made of forged 6061-T6 and 7075-T6 aluminum alloys. Because of good thermal conductivity, these aluminum wheel spacers will dissipate brake heat better. This is good for rims or brakes. They feature nicer designs that add both style and function. Apart from the base functions of spacers, BONOSS forged active cooling Mazda 3 wheel spacers provide more practical advantages.

The best advantage of this is the active cooling function. There are petal-shaped grooves carved on the back sides. These heat dissipation grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates. The air takes away the heat, so it achieves the purpose of actively dissipating heat for the braking system. These BONOSS forged active cooling wheel spacers help make brake cooling better.

Can Mazda 3 Wheel Spacers Affect Fail?

As long as you torque each wheel nut correctly, genuine brand Mazda 3 wheel spacers won’t fail easily. They are upgrading parts to give your Mazda 3 cars better performance as well as a unique look, especially if you’re taking it to racing events. To ensure a stable and firm wheel connection, a BONOSS forged active cooling Mazda 3 wheel spacer kit comes with ISO grade 12.9 wheel studs (tensile strength over 1220 MPa) and ISO grade 10 wheel nuts (proof load over 1,100 MPa). Even facing impacts, these wheel fasteners are not easy to break.

What’s better, these BONOSS forged active cooling Mazda 3 wheel spacers come with full-cone lug seats. Full-cone seat design provides a larger contact area, more force acreage, and better fitting. This allows the studs and nuts to apply enough clamping force to lock the BONOSS forged active cooling Mazda 3 wheel spacers, avoiding any potential loosening risks. In that case, the axle-spacer-wheel connection can be fastened firmly, meaning no vibration, fewer stress loads, higher safety, and a longer service life range.
