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 offer durability, reduced unnecessary rotating mass, and responsive handling characteristics.

Flow formed construction provides enthusiasts with a performance-oriented alternative to traditional cast wheels without the expense associated with fully forged wheel designs.

Lightweight 18.57 lb Construction

At approximately 18.57 lbs, the 18x8.5 Heliogram offers excellent weight efficiency for its diameter and width.

Reducing unnecessary rotating and unsprung weight may contribute to improvements in:

• Steering response.

• Suspension responsiveness.

• Acceleration characteristics.

• Braking response.

• Overall handling feel.

Actual performance improvements 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 layout creates an aggressive appearance while helping reduce unnecessary material and weight.

The design also provides visibility of the vehicle's brake components, making it a popular styling choice for performance vehicles equipped with upgraded braking systems.

The split five-spoke configuration delivers a balance of modern styling and lightweight engineering suitable for street and track applications.

Titanium Metallic Finish

The HL8851442T features Konig's premium Titanium Metallic finish.

This metallic gray finish highlights the wheel's spoke design and provides a refined appearance with a distinctive motorsport influence.

The finish complements a wide range of vehicle colors and offers an alternative to traditional gloss black, silver, or 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 performance-oriented driving applications.

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

18x8.5 +42 Wheel Fitment

The 18x8.5-inch configuration provides a versatile platform for appropriately sized performance tires.

The +42mm offset determines the wheel's mounting position relative to its centerline and affects both inner suspension clearance and outer fender clearance.

Compared with wider, lower-offset configurations, this wheel may provide a more conservative fitment on certain vehicles. However, compatibility depends on the original wheel dimensions and the complete wheel and tire combination.

Potential installation considerations include:

• Factory or aftermarket suspension clearance.

• Brake caliper clearance.

• Tire width and sidewall selection.

• Fender clearance.

• Steering clearance.

• Alignment and camber settings.

• Hub-centric ring requirements.

Proper fitment should always be confirmed before installation.

73.1mm Center Bore

The Heliogram HL8851442T 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 configurations.

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

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

Performance Tire Compatibility

The 18x8.5-inch width supports a variety of performance tire configurations when matched with tire manufacturer specifications.

Potential applications include:

• High-performance summer tires.

• All-season performance tires.

• Extreme-performance street tires.

• Track-oriented tire compounds.

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

Always confirm that the selected tire is approved for mounting on an 8.5-inch-wide wheel.

Common Reasons for Replacement

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

• Reduced Rotating Weight: Provides an alternative to heavier factory or aftermarket wheels.

• Performance Tire Upgrade: Supports appropriately sized performance tires.

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

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

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

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

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

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

14. Install the Center Cap: Secure the matching Konig center cap according to the manufacturer's instructions.

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.
