5x114.3mm to 5x100mm Wheel Adapters 1in Thick - Change Bolt Pattern

In this review the KAX 5x114.3mm to 5x100mm wheel adapters are evaluated for drivers who need to fit 5x100mm wheels to a 5x114.3mm hub. The bottom line: these 1in (25mm) adapters are best for owners looking to change bolt pattern and move wheels outward for clearance or stance, and they deliver solid construction and straightforward hardware. The review focuses on fit, materials, and ease of installation based on the supplied components and customer feedback.

Key Features

• Bolt pattern conversion: Converts a 5x114.3mm vehicle hub to accept 5x100mm wheels so users can mount a different wheel fitment without replacing hubs.
• 1in thickness: The 25mm thickness provides measurable offset change for clearance or appearance while maintaining a short profile that usually avoids excessive trimming.
• Forged 6061-T6 aluminum: Forging from aircraft quality aluminum yields a strong, lightweight adapter that resists deformation under normal driving conditions.
• M12x1.5 studs and 10.9 nuts: Supplied M12x1.5 threaded studs and SGS certified 10.9 class split nuts give reliable fastening and long-term durability.
• 73.1mm hub bore: Hub centric 73.1mm bore centers the adapter on the vehicle hub for consistent alignment and reduced vibration when matched correctly.
• Installation guide included: The package includes four adapters, nuts and a professional instruction manual to assist with torque and fitting recommendations.

Who It's For

This product is aimed at drivers of vehicles with a 5x114.3mm bolt pattern who want to use 5x100mm wheels, including many late model Accords, Civics, Camrys, RAV4s and a range of other cars and crossovers listed in the compatibility notes. It is particularly useful for enthusiasts who need a modest offset change of 1in to clear calipers, fenders, or to achieve a wider stance.

Those who should look elsewhere include drivers with less than 2in of clearance between fender and tire or vehicles with factory wheel studs longer than the adapter thickness without the intention to trim studs. Also, any user unsure of hub bore or bolt pattern compatibility should verify measurements before purchase.

Pros & Cons

Pros

• Solid build from forged 6061-T6 aluminum offers strength without excessive weight.
• Complete hardware kit with M12x1.5 studs and SGS certified 10.9 nuts simplifies installation.
• Hub centric 73.1mm bore helps maintain balance and reduce vibration when matched correctly.

Cons

• Fit receives mixed feedback from some customers, so precise measurement and verification are necessary before installation.
• Adapters add 1in of offset which can require trimming or checking for clearance on some vehicles.
