BDFHYK 5x114.3 Wheel Spacers- 15/20mm, 56.1mm Hub Bore, M12x1.25 Studs, Fits Subaru WRX, STI, Forester, Impreza, Legacy, Outback, Set of 4

15 mm or 20 mm 5x114.3 Hubcentric Wheel Spacers for Subaru

These BDFHYK wheel spacers are designed for compatible Subaru WRX, WRX STI, Forester, Impreza, Legacy, Outback, Ascent, and other listed applications using a 5x114.3 bolt pattern, 56.1 mm hub bore, and M12x1.25 wheel hardware. Each selected variant includes four spacers.

Choose the Thickness or Package for Your Setup

• 15 mm: A moderate outward shift for stock or aftermarket wheels when measurements show that only limited additional spacing is needed.
• 20 mm: A larger effective-offset change when the wheel must move farther outward for measured inner clearance or wheel-position goals.

A thicker spacer creates a larger effective-offset change. More inner clearance also means less room at the fender and wheel-well liner, so choose by measurement rather than appearance alone.

Key Fitment Specifications

• Bolt pattern: 5x114.3 / 5x4.5
• Center bore: 56.1 mm
• Thread pitch: M12x1.25
• Package: Set of 4 in the selected thickness
• Listed applications: Compatible Subaru WRX, WRX STI, Forester, Impreza, Legacy, Outback and Ascent applications

Common Reasons to Use Wheel Spacers

• Move compatible wheels outward when they sit too far inward.
• May provide additional room near inner tire, brake, or suspension components.
• Support selected aftermarket wheel offsets when all hub and hardware dimensions match.
• Create a more even wheel position across the front and rear when axle measurements support it.

Fitment Checks Before Ordering

Confirm the vehicle and wheel bolt pattern, hub diameter, wheel center bore, thread pitch, wheel offset, tire size, lug-seat style, brake package, and suspension setup. Measure original stud protrusion and wheel-pocket depth so the wheel can seat fully flat. Check clearance at ride height, full steering lock, and expected suspension compression. Exact requirements can vary by model year, trim, wheel design, and previous modifications.

Installation and Maintenance

Clean all mounting faces and confirm full hub-to-spacer and spacer-to-wheel contact. Tighten compatible hardware in a star pattern using a calibrated torque wrench and the applicable specification. Do not stack spacers or use damaged studs or lug nuts. Recheck torque after initial driving and during routine tire service. Professional installation is recommended if any fitment dimension is uncertain.
