Konig Flow Forming Technology

The Heliogram utilizes Konig's Flow Forming Technology, a manufacturing process that combines a cast aluminum wheel center with a barrel formed under pressure and rotation.

During manufacturing, the wheel barrel is stretched and shaped to its final dimensions. This process improves the aluminum's strength-to-weight characteristics compared with conventional cast wheel construction.

The result is a lightweight performance wheel designed to provide durability and reduced unnecessary rotating mass.

Flow formed construction offers an attractive alternative for enthusiasts seeking modern performance wheel technology without the cost associated with fully forged wheels.

Lightweight 21.9 lb Construction

At approximately 21.9 lbs, the 18x12 Heliogram offers impressive weight efficiency for its exceptionally wide configuration.

Reducing unnecessary rotating and unsprung weight may contribute to improvements in steering response, suspension responsiveness, acceleration, and braking characteristics compared with heavier wheel configurations.

Actual performance benefits depend on the weight and specifications of the original wheel and tire combination.

Motorsport-Inspired Split Five-Spoke Design

The Heliogram features a distinctive split five-spoke design inspired by modern motorsport wheels.

Its open spoke configuration creates an aggressive appearance while emphasizing the wheel's wide proportions and concave face profile.

The design provides a balance of visual appeal and lightweight construction, making it suitable for enthusiasts seeking a bold performance wheel.

Titanium Metallic Finish

The HL2851420T features Konig's premium Titanium Metallic finish.

This metallic finish highlights the wheel's split five-spoke design and concave profile, creating a refined appearance with a distinctive motorsport influence.

The finish complements a wide range of vehicle colors and provides an alternative to traditional black, silver, and bronze wheels.

Knurled Bead Seat Technology

The Heliogram incorporates knurled bead seats designed to increase friction between the tire bead and wheel.

During aggressive acceleration, braking, and cornering, high forces can cause a tire to move slightly relative to the wheel.

The textured bead seat helps resist this movement, making it particularly useful for high-horsepower and track-oriented applications.

Note: Knurled bead seats are not beadlocks and do not eliminate the need for proper tire mounting, inflation, or maintenance.

18x12 +20 Wheel Fitment

The 18x12-inch configuration provides an exceptionally wide platform for appropriately sized performance tires.

The +20mm offset determines the wheel's mounting position relative to its centerline and affects both inner suspension clearance and outer fender clearance.

This wheel configuration may require:

• Wide-body fenders or substantial body modifications.

• Custom suspension geometry.

• Appropriate tire width and sidewall selection.

• Additional negative camber where suitable.

• Verification of steering and suspension travel.

• Careful brake clearance evaluation.

• Proper wheel stud and lug hardware selection.

This is a specialized performance wheel configuration and is not intended as a universal factory replacement.

73.1mm Center Bore

The Heliogram HL2851420T features a 73.1mm center bore.

Vehicles with smaller hub diameters may require appropriately sized hub-centric rings to help center the wheel during installation.

Hub-centric rings do not correct an incompatible bolt pattern, incorrect lug hardware, or insufficient brake clearance.

Performance Brake Clearance

The Heliogram features an open split five-spoke design that may accommodate various factory and aftermarket brake systems.

However, compatibility with larger brake calipers depends on the specific brake system, rotor dimensions, wheel offset, and spoke clearance.

Always verify brake clearance using an appropriate manufacturer-approved brake template before purchasing.

Wide Performance Tire Applications

The 18x12-inch width is intended for appropriately sized wide performance tires.

Potential applications include:

• High-performance summer tires.

• Extreme-performance street tires.

• Track-oriented tire compounds.

• Dedicated motorsport tire configurations.

Tire selection must account for the vehicle's drivetrain, suspension geometry, available clearance, and intended use.

Always confirm that the selected tire is approved for mounting on a 12-inch-wide wheel.

Common Reasons for Replacement

• Factory Wheel Upgrade: Replaces original wheels on appropriately modified vehicles with a lightweight performance-oriented design.

• Wider Tire Configuration: Provides a 12-inch-wide wheel for compatible high-performance tire setups.

Installation Notes

1. Verify Bolt Pattern: Confirm that the vehicle uses a 5x114.3 bolt pattern.

2. Check Wheel Dimensions: Ensure the 18x12 +20 configuration is appropriate for the vehicle.

3. Confirm Center Bore Compatibility: Determine whether hub-centric rings are required.

4. Verify Brake Clearance: Check clearance around factory or aftermarket brake calipers.

5. Inspect Suspension Clearance: Ensure sufficient clearance around struts, coilovers, control arms, and related components.

6. Check Fender Clearance: Verify that the wheel and tire combination will not contact the fenders during steering or suspension compression.

7. Select Compatible Tires: Use tire sizes approved for a 12-inch-wide wheel and appropriate for the vehicle.

8. Evaluate Body Modifications: Determine whether wide-body fenders or additional clearance modifications are necessary.

9. Use Proper Lug Hardware: Install lug nuts or bolts with the correct thread specifications, seat profile, and engagement.

10. Inspect Hub Mounting Surfaces: Clean corrosion and debris from the wheel mounting surfaces.

11. Install Hub-Centric Rings if Required: Use appropriately sized rings when the wheel center bore is larger than the vehicle's hub.

12. Install TPMS Sensors: Use compatible tire pressure monitoring sensors where required.

13. Mount and Balance Tires: Have tires professionally installed and balanced.

14. Torque Lug Hardware: Follow the vehicle manufacturer's specified tightening sequence and torque requirements.

15. Verify Final Fitment: Check wheel and tire clearance throughout the required suspension and steering travel.

16. Recheck Lug Torque: Follow the applicable wheel and vehicle manufacturer recommendations after initial driving.

17. Maintain the Finish: Clean using wheel-safe products suitable for metallic-painted aluminum wheels.

Important: Additional components such as hub-centric rings, aftermarket lug nuts, extended wheel studs, or spacers may be required depending on the vehicle. All supporting hardware must be selected for the specific application.
