Product compatibility notes: adapters vary by hub bore, wheel bore, and vehicle studs. The selections below prioritize common 4×100 to 4×114.3 conversions used on Honda, Toyota, Acura, Mazda, and similar models. All options rely on 12×1.5 studs and 71 mm or 67.1 mm hub bores where specified. When in doubt, verify wheel bore clearance and stud length before installation.
OCPTY 4X 4 Lug Wheel Adapters 15mm 4×100 To 4×114.3
Key features: 15 mm thickness, 71 mm center bore, 12×1.5 thread, forged 6061-T6 aluminum, compatible with a wide list of 4×100 vehicles. Best for drivers seeking a mid-width spacer that maintains hub seating and a robust mounting surface. This option is well suited for those who want a safer, forged alternative over cast spacers. Caution: ensure your wheels have enough backpad clearance to seat flush with the hub; misalignment can cause contact with studs.
Titan Wheel Accessories 1 Inch Adapters
Key features: 1″ thick adapters, 67.1 mm bore, 12×1.5 studs, CNC-machined 6061-T6 billet aluminum, black anodized finish. Best for drivers wanting a simple, consistent increase in track width for improved stability and aggressive stance on 4×100 hubs. Choose this if you prefer stronger billet aluminum with corrosion resistance. Caution: some wheels may require machinist attention to fitment around the hub clearance bore.
EZAccessory 4 Wheel Adapters 4×100 to 4×114.3
Key features: 1″ thick spacers, forged 6061 T6, CNC-machined, corrosion-resistant black anodized finish, includes high-load capacity hardware. Best for drivers who need a balanced mix of lightweight performance and rugged reliability. Better for daily driving and occasional track use. Limitation: some wheels may require additional backpad clearance to seat properly.

Key features: 15 mm width, 71 mm center bore, M12x1.5 studs, includes two adapters per set, critical fitment note about backpad clearance and potential stud trimming. Best for users who need precise 4×100 to 4×114.3 conversion with clear installation notes. Choose this if your wheels have adequate backpad depth to clear the factory studs. Caution: wheels may require stud trimming to seat flush, which can affect fastener engagement if not done correctly.
Customadeonly 4×114.3 to 4×100 15mm Hubcentric Adapters
Key features: 15 mm thick, hubcentric 64.1 mm inner bore and 54.1 mm outer lip, four pieces, 12×1.5 studs. Best for achieving precise centering when converting 4×114.3 wheels to 4×100 hubs, with hub rings optional for size mismatches. Choose this if center alignment matters for balancing and road feel. Limitation: potential need to trim factory studs depending on wheel clearance.
Buying Guide: Key Purchase Considerations
What bolt pattern do you need to convert?
Confirm your vehicle’s hub pattern (4×100 is common on many older Hondas, Toyotas, and Mazdas) and ensure the adapter converts to 4×114.3 (4×4.5).
What is the correct thickness?
Adapter thickness (6 mm, 15 mm, or 20 mm) affects wheel offset and brake clearance. Choose thickness that provides the needed stance without rubbing or wheel misalignment.
Is hub bore compatibility crucial?
Center bore compatibility prevents centering issues. Adapters with a 71 mm or 67.1 mm bore fit specific hubs; mismatches may require hub rings to ensure proper seating.
Are there notes about backpad clearance?
Backpad clearance is essential for flush seating. Some 15 mm spacers require 11 mm of backpad depth. If your wheels lack pockets, stud trimming may be necessary, which can affect seating and safety.
What about hardware and installation?
Look for forged aluminum spacers with high-grade studs (12×1.5) and corrosion-resistant finishes. Ensure you have the correct lug nuts and the proper torque specifications for safe installation.
Will these affect handling or warranty?
Adapters add width and may alter weight distribution. They can influence braking feel and steering response. Always verify compatibility with your vehicle’s warranty and confirm that the installation does not interfere with any suspension or brake components.
What are common limitations to expect?
Common limitations include clearance with certain wheels, the need for stud trimming, and potential alignment changes. If a wheel’s center bore is smaller than the adapter’s bore, you may need hub-centric rings to ensure accurate centering.
FAQ
- Q: Do 15 mm spacers require special wheel pockets?
A: Yes, many 15 mm spacers require backpad pockets at least 11 mm deep to seat flush and avoid stud interference. - Q: Can any 4×100 wheel fit with these adapters?
A: Compatibility depends on the wheel bore, hub bore, and clearance around the brake components; verify before purchase. - Q: Are forged spacers safer than cast spacers?
A: Forged spacers (like 6061-T6 aluminum) generally offer higher strength and stability than cast spacers, reducing deformation risk under load. - Q: Will adapters affect wheel alignment?
A: They can affect alignment by changing track width; have a professional check alignment after installation. - Q: Do these adapters include all mounting hardware?
A: Most sets include studs and lug hardware, but confirm included items in the product listing before buying. - Q: Is hub-centric alignment important?
A: Yes, hub-centric designs reduce vibration and balancing issues by aligning the wheel to the hub precisely.
