Cast Aluminum Construction & Performance Benefits

The Konig Backbone utilizes one-piece cast aluminum construction, a proven wheel manufacturing process designed to provide dependable strength, consistent quality, and affordability.

During manufacturing, molten aluminum is poured into a precision-engineered mold to form the wheel's structure. Once cooled, the wheel undergoes additional machining, finishing, and quality-control procedures to achieve its final dimensions and appearance.

Benefits of cast aluminum construction include:

• Durable Construction: Engineered to provide dependable performance for compatible street-driven vehicles.

• Weight-Conscious Design: Aluminum construction helps reduce weight compared to many heavier wheel alternatives.

• Cost-Effective Performance Styling: Delivers distinctive aftermarket styling without the expense of fully forged wheels.

• Consistent Manufacturing: Precision casting provides repeatable wheel dimensions and design characteristics.

• Everyday Versatility: Suitable for compatible daily-driven and street performance applications.

At approximately 13.4 pounds, the Backbone offers an attractive weight for a 15x6.5-inch aftermarket wheel.

Backbone Design & Fitment Considerations

The Konig Backbone features a distinctive six-spoke design with a muscular appearance and unique dual lightening-hole details. Its Matte Black finish and machined spoke accents create a clean, aggressive look that complements both classic and modern sport-compact vehicles.

The 15x6.5-inch width and +38mm offset provide a versatile configuration for many compact vehicles with compatible wheel and tire clearance.

For Honda and Acura enthusiasts, the 4x100 bolt pattern makes this wheel particularly relevant to older Civic, CRX, Del Sol, and Integra platforms retaining their original four-lug hub configurations.

However, actual fitment depends on the vehicle's suspension geometry, brake package, tire selection, and available fender clearance.

The 73.1mm center bore may require vehicle-specific hub-centric rings to properly center the wheel on smaller factory hubs.

Vehicles equipped with aftermarket brake upgrades should be checked using the brake manufacturer's wheel clearance template before installation.

Important: The Backbone's 15-inch diameter and six-spoke design do not guarantee clearance for every factory or aftermarket brake package.

Common Reasons for Replacement

• Factory Wheel Upgrade: Replace original equipment wheels with a lightweight, stylish aftermarket alternative.

• Improved Vehicle Styling: Enhance the vehicle's appearance with bold six-spoke styling and a Matte Black finish.

• Classic Sport Compact Builds: Complete a Honda Civic, CRX, Del Sol, or Integra project with a traditional 15-inch performance wheel.

• Performance Tire Compatibility: Accommodate appropriately sized street or performance tires.

• Custom Vehicle Builds: Upgrade the appearance of a modified Honda, Acura, or other compatible four-lug vehicle.

• Damaged Wheel Replacement: Replace bent, cracked, or cosmetically damaged factory or aftermarket wheels.

• Matching Wheel Replacement: Replace an existing Konig Backbone wheel with the same dimensions, offset, bolt pattern, and finish.

Installation Notes

1. Verify Vehicle Compatibility: Confirm the 15x6.5-inch size, +38mm offset, and 4x100 bolt pattern are appropriate for your vehicle.

2. Check Hub Compatibility: The 73.1mm center bore may require appropriately sized hub-centric rings for vehicles with smaller factory hubs.

3. Confirm Brake Clearance: Verify adequate clearance around factory or aftermarket brake calipers, especially when using upgraded brake systems.

4. Use Proper Lug Hardware: Confirm the wheel's required lug-seat design and install compatible lug nuts with the correct thread pitch, seat profile, and engagement. Factory Honda ball-seat lug nuts should not be reused unless specifically approved for the wheel.

5. Select Appropriate Tires: Choose tires approved for installation on a 6.5-inch-wide wheel and appropriate for your vehicle's intended use.

6. Inspect Suspension and Fender Clearance: Verify adequate clearance throughout steering and suspension travel.

7. Maintain Proper Tire Diameter: Select an appropriate tire profile to maintain suitable overall tire diameter and minimize unnecessary changes to speedometer accuracy.

8. Install TPMS Sensors: Transfer or install compatible tire pressure monitoring sensors when required.

9. Torque Wheel Hardware: Tighten lug nuts to the vehicle manufacturer's recommended torque specifications.

10. Perform Final Fitment Inspection: Confirm proper wheel seating, tire clearance, brake clearance, and secure installation before driving.
