How to ensure wheel spacers safe? The first factor is the material.
BONOSS wheel spacers apply forged 6061-T6 (tensile strength≥310Mpa) or 7075-T6 (tensile strength≥572Mpa) billet aluminum material,
which ensures higher strength, service range, and safety than those cheap casting aluminum spacers.
Without spacers, your big brake caliper may not fit the stock wheels. By pushing out the wheel,
you can gain the ideal amount of clearance for a bigger brake instead of rubbing against it when mounting back the wheel.
