15mm Wheel Adapters 5×100 to 5×120 (Hub to Wheel) For Subaru
These 15mm adapters convert a 5×100 hub to a 5×120 wheel bolt pattern while remaining hubcentric with a 56.1mm center bore. They use M12x1.25 threads and come in a 4-piece set. Factory studs may require trimming if they interfere with wheel fitment. CNC machining ensures consistent tolerances to promote balanced rotation and proper seating on Subaru platforms that use 5×100 hubs.
Customadeonly Forged 5×100 to 5×120 Adapters, 20mm Thick
Two 20mm spacers provide a robust option for converting 5×100 hubs to 5×120 wheels. Center bore is 57.1mm, and the kit uses M12x1.5 studs. The product notes emphasize compatibility checks prior to ordering since wheels must be confirmed for 5×120 fitment. Anodized aluminum construction and CNC precision support a stable stance and improved handling when used with aftermarket wheels.
Customadeonly Forged 5×120 to 5×100 Wheel Adapters, 25mm Hubcentric
This 2-piece kit converts 5×120 hubs to 5×100 wheels with a 72.6mm hub bore on the hub side and 54.1mm on the wheel side, offering a centralized, precision fit. Manufactured from high-grade T-6 aluminum and CNC-machined for precise tolerances, the adapters support improved handling and a more aggressive stance. Factory stud trimming may be required depending on OEM stud length, so verify wheel clearance ahead of installation.
Customadeonly 5×120 to 5×100 Wheel Adapters, 2pcs 25mm Thick
This pair of 25mm thick adapters converts 5×120 hubs to 5×100 wheels, featuring 72.6mm bore on the hub side and 54.1mm bore on the wheel side. M12x1.5 studs and anodized finish contribute to solid construction and corrosion resistance. As with similar products, some factory studs may need trimming for proper clearance, and users should confirm wheel compatibility and clearances before installation.
Buying Guide: Key Purchase Considerations
Purpose and fitment: Ensure the adapters match your vehicle’s hub thickness, bolt pattern, and center bore. Many adapters specify hubcentric design to minimize vibrations and improve balance. If your wheel bore exceeds the adapter’s center bore, hub rings can help achieve a proper fit.
Center bore compatibility: A 56.1mm or 57.1mm bore is common for 5×100 to 5×120 conversions; larger bores may require hub rings for proper seating. Verify that the wheel’s center bore is compatible or plan for a hub-centric spacer solution.
Studs and trimming: Factory studs can be longer than necessary when paired with adapters, which may require trimming. Check thread pitch (13×1.25 vs 12×1.25 vs 1.5) and confirm compatibility with your wheel and lug nuts before installation.
Material and finish: CNC-machined aluminum spacers and adapters offer strength and precision with a light weight. Anodized finishes resist corrosion and maintain appearance over time, especially for daily drivers and performance cars.
Load rating and safety: Choose adapters rated for your vehicle’s weight and driving conditions. Follow manufacturer torque specs and installation instructions to ensure safe mounting and proper seating each time the suspension is cycled and wheels are rotated.
Compatibility checks: Confirm whether the vehicle’s OEM wheels are compatible with a 5×120 bolt pattern or if there’s any interference with brake calipers, rotor hats, or wheel lips. When in doubt, consult the wheel manufacturer or a professional installer.
Warranty and support: Look for products with warranty coverage and access to customer support for fitment questions and potential returns or exchanges. A clear return policy helps reduce risk when attempting a bolt pattern change.
These five adapters provide multiple thickness options (15mm, 20mm, and 25mm) to help users achieve the correct offset, improved stability, and a more aggressive stance when pairing 5×100 hubs with 5×120 wheels. Always verify wheel compatibility, center bore requirements, and potential stud trimming before purchasing and installation.
