With Mazda hub-centric wheel spacers, you don’t have to spend a large budget on aftermarket wheels while improving the appearance of your vehicle. Their thicknesses vary from about 1/8″ all the way up to 2″ or more. If you intend to make your Mazda look sportier and more noticeable without changing wheels, then the thickness will be determined by the distance from the edge of the fender to the face of the tire.

Performance & Material

Forged Aircraft Aluminum

Aluminum Alloy Perfromance

BONOSS forged Mazda wheel spacers are safer and stronger than those casting alternatives: Tensile Strength ≥ 310Mpa (AL6061-T6), Tensile Strength ≥ 572Mpa (AL7075-T6), Yield Strength ≥ 275Mpa (AL6061-T6), Yield Strength ≥ 503Mpa (AL7075-T6), and the Tensile Strength of the cheap alternatives is approximately 125Mpa below. This means our forged Aluminum Mazda wheel spacers provide stronger impact resistance, less fatigue strength, longer service life range, and stronger corrosion resistance.

ISO Grade 12.9 Wheel Studs

Wheel Studs (SCM440)

The matching wheel studs of BONOSS Mazda spacers applied high-strength JIS SCM440 steel material. Take the matching wheel studs as an example, they have achieved ISO standard grade 12.9, tensile strength ≥ 1,220Mpa, limited life range test ≥ 2,000,000 stress cycles without damage, ultimate tensile load ≥ 152,000N, hardness (HV) ≥ 395, NSS ≥ 500H… And the matching lug nuts have achieved ISO standard grade 10, proof load ≥ 1110Mpa, hardness (HV) ≥ 349
