5x100 Hubcentric Wheel Spacers 1 Inch for Subaru BRZ Impreza FR-S Exiga, M12x1.25 Studs, 56.1mm Hub Bore, Set of 4

5x100 Hubcentric Wheel Spacers for Subaru BRZ, Impreza, FR-S, and Exiga

These BDFHYK 5x100 hubcentric wheel spacers move compatible wheels outward by 1 inch, or approximately 25 mm. They are intended for vehicle and wheel setups that match a 5x100 bolt pattern, 56.1 mm center bore, and M12x1.25 wheel-stud thread pitch. The four-piece package is designed for drivers who want to adjust both front and rear wheel position with the same thickness.

A spacer can be useful when an aftermarket wheel has a high positive offset, the tire sits close to a strut or coilover, or the factory wheel position looks deeply tucked inside the fender. The spacer changes effective wheel offset, so it must be selected from measurements rather than from vehicle name alone.

Scenario-Based Fitment Solutions

• Inner tire-to-strut clearance: The 1 inch thickness may create more room between the inner tire sidewall and the strut, spring perch, or coilover body.
• High-offset replacement wheels: Moving the wheel outward can help correct an overly inward wheel position when the bolt pattern and center bore already match.
• Brake and wheel-barrel clearance: Additional wheel position may help with some spoke or barrel clearance issues, but the wheel must still clear the caliper and rotor during a test fit.
• Front and rear stance adjustment: A set of four supports a consistent 1 inch change at all four corners when the complete vehicle has enough fender clearance.

What the 1 Inch Thickness Changes

A 1 inch spacer moves each installed wheel outward by about 25 mm. This is a significant offset change. Before ordering, measure the existing inner clearance and the available space between the tire and the fender. Also consider tire sidewall bulge, wheel width, alignment, ride height, steering angle, and suspension compression.

If the vehicle is lowered or uses wider tires, test clearance at full steering lock and through the expected suspension travel. A setup that clears while parked can still contact the fender liner or body under cornering, braking, or road impact.

Required Fitment Specifications

• Vehicle bolt pattern: 5x100
• Wheel bolt pattern: 5x100
• Hub bore: 56.1 mm
• Thread pitch: M12x1.25
• Spacer thickness: 1 inch / approximately 25 mm
• Package quantity: Set of 4
• Design: Hubcentric bolt-on wheel spacer

These dimensions are critical. Do not substitute M12x1.5 hardware for the specified M12x1.25 thread pitch. Verify that both the vehicle hub and wheel center bore are compatible with the 56.1 mm hubcentric interface.

Stud, Wheel Pocket, and Fender Checks

Measure how far the original vehicle studs extend beyond the installed spacer mounting surface. If they protrude, the back of the wheel must have pockets deep enough to accept them without contact. The wheel must seat fully against the spacer with no gap.

Install only on clean, flat hub surfaces. Follow the correct torque specification and tightening sequence, then re-check torque after initial driving. Inspect brake, suspension, tire, and fender clearance before normal road use. Do not stack wheel spacers, and use professional installation if the wheel offset or stud-clearance measurements are uncertain.
