Upgrade your stance and wheel fitment with American-made precision. BSB USA wheel spacers are engineered and machined in the United States from high-strength 6061-T6 billet aluminum. Each spacer is CNC-machined to exact tolerances with a precision-machined 56.1mm center bore for an accurate hubcentric fit, then anodized black for corrosion protection and a clean finish.
Built for Subaru vehicles with a 5x4.5 bolt pattern and 56.1mm hub, including the WRX, WRX STI, Impreza, Forester, Outback, Legacy, Crosstrek, and Ascent. These 1/2" (12mm) slip-on spacers move each wheel outward 1/2 inch, adding clearance for brake calipers and suspension components and filling out the stance for wider wheels and tires.
Features:
- CNC-machined from solid 6061-T6 billet aluminum

- Slip-on design: slides over your factory wheel studs and uses your original lug nuts

Installation:
Clean the hub face, slide the spacer over the factory studs until it sits flush on the hub, then mount the wheel with your original lug nuts. Confirm full thread engagement on every lug nut (8 turns on 12x1.25, 6.5 turns on 12x1.5); if your studs are too short, install extended wheel studs before use. Torque with a hand torque wrench to the factory spec, not to exceed 110 ft-lbs, and re-check torque after the first 25 miles.
