5x100 to 5x112 Hubcentric Wheel Adapters 20mm for Audi A4 A6 Volkswagen Jetta Beetle Golf, M14x1.5 Studs, 57.1mm Hub Bore, Set of 2

20 mm 5x100 to 5x112 Wheel Adapters for Wheel-Pattern Conversion

These BDFHYK wheel adapters convert a compatible 5x100 vehicle-side mounting pattern to a 5x112 wheel-side pattern. They are intended for wheel-swap projects where the vehicle hub is confirmed as 5x100 and the selected wheel is confirmed as 5x112. The 20 mm adapter thickness also moves the wheel outward, so it must be evaluated as both a bolt-pattern conversion and an offset change.

The product title references selected Audi and Volkswagen applications, but model names such as A4, A6, Jetta, Beetle, and Golf include generations with different factory hubs and bolt patterns. Fitment should be confirmed from the exact vehicle and wheel measurements rather than from the model name alone.

Scenario-Based Uses for This Adapter

• Install compatible 5x112 wheels: Provides the required bolt-pattern transition from a 5x100 vehicle hub to a 5x112 wheel.
• Create additional inner wheel clearance: The 20 mm outward change may help when the replacement wheel is too close to brakes, suspension, or inner wheel-well surfaces.
• Correct an inward wheel position: Can help when the selected wheel has a high positive offset and sits too far inside the body line.
• One-axle wheel conversion: The set of two covers one axle when the same measured setup is required on both sides.

Key Conversion Parameters

• Vehicle-side bolt pattern: 5x100
• Wheel-side bolt pattern: 5x112
• Adapter thickness: 20 mm
• Center bore: 57.1 mm as listed
• Thread specification: M14x1.5
• Package quantity: Set of 2
• Adapter function: Changes bolt pattern and wheel position at the same time

When to Choose 20 mm Instead of 15 mm

The 20 mm version moves the wheel 5 mm farther outward than a 15 mm adapter. It may be appropriate when more inner clearance is required or when the selected wheel sits noticeably inward. That additional movement also places the tire closer to the fender and liner. Measure the proposed wheel width and offset, then compare the final inner and outer position before choosing the thicker adapter.

Required Fitment Checks

• Verify that the vehicle side is 5x100 and the replacement wheel side is 5x112.
• Confirm the 57.1 mm bore is compatible with the vehicle hub and selected wheel interface.
• Confirm M14x1.5 hardware, lug-seat type, and usable thread engagement.
• Check the replacement wheel center bore and mounting-pad shape.
• Inspect brake-caliper, suspension, tire, fender, liner, and steering clearance.
• Calculate effective wheel offset after adding the 20 mm adapter.
• Confirm whether one set of two or two sets are required for the intended axle configuration.

Installation and Ongoing Inspection

The adapter and wheel must sit fully flush on clean, undamaged mounting faces. Use compatible hardware and a calibrated torque wrench, following the applicable tightening sequence and torque specification. Do not stack adapters, add separate spacers, or install over damaged studs, bolts, or lug seats. Recheck torque after initial driving and inspect the assembly whenever the wheels are removed.
