5x114.3 Wheel Spacers 1 Inch for Nissan 350Z 370Z Infiniti G35 G37 FX35, M12x1.25 Studs, 66.1mm Hub Bore, Set of 4, Not Hubcentric

1 Inch 5x114.3 Wheel Spacers for Nissan and Infiniti

These BDFHYK 5x114.3 / 5x4.5 wheel spacers are designed for compatible Nissan 350Z, 370Z, and selected Infiniti G35, G37, and FX35 applications using M12x1.25 wheel hardware. Each spacer is 1 inch / 25.4 mm thick with a 66.1 mm center bore, and the package contains four spacers.

This listing is for a non-hubcentric wheel spacer. Although the center-bore dimension is 66.1 mm, that measurement alone does not make the spacer hubcentric. The spacer must be centered through compatible lug hardware and installed with clean mounting faces, even seating, and gradual star-pattern tightening.

Scenario-Based Fitment Solutions

• A tucked wheel position: Moving compatible wheels outward by approximately 1 inch may create a more filled-out position relative to the fender.
• Inner tire rubbing: The spacer may provide additional room near suspension arms, struts, liners, or other inner components when the interference is confirmed by measurement.
• Aftermarket wheel offset mismatch: It can compensate for selected high-positive-offset wheels that otherwise sit too far inward, provided all bolt-pattern, bore, and hardware requirements match.
• Brake or wheel-barrel clearance: The outward shift may help with selected caliper, spoke, or barrel-clearance issues, but wheel shape must be checked directly.
• Four-corner spacing: A set of four supports the same change at the front and rear only when both axles have sufficient inner and outer clearance.

What a 1 Inch Spacer Changes

A 1 inch spacer makes a substantial change to effective wheel offset. It may improve clearance on the inner side of the wheel, but it also reduces available room at the fender and wheel-well liner. Measure the current wheel position at ride height, then check full steering lock and suspension compression. Lowered vehicles, aggressive alignment, wider tires, and aftermarket brake packages need especially careful checks.

Fitment and Pre-Installation Checks

• Confirm the vehicle and wheel use a 5x114.3 bolt pattern and M12x1.25 hardware.
• Verify the 66.1 mm center bore clears the vehicle hub and is compatible with the wheel-side mounting surface.
• Confirm wheel offset, wheel width, tire size, lug-seat style, brake package, and suspension setup.
• Measure original stud protrusion and wheel-pocket depth so the wheel can sit fully flat.
• Check fender, liner, brake, and suspension clearance at full lock and through expected suspension travel.

Installation and Maintenance

Clean all contact surfaces until they are flat and free of rust, paint buildup, and debris. Hand-start the hardware, tighten gradually in a star pattern, and finish with a calibrated torque wrench using the applicable specification. Do not stack wheel spacers or use damaged studs, lug nuts, or uneven mounting surfaces. Recheck torque after initial driving and inspect the spacers whenever the wheels are removed or rotated.
