Flow Forming Technology & Performance Benefits

The Konig Ampliform utilizes Flow Forming Technology, an advanced manufacturing process designed to improve wheel barrel strength, durability, and overall performance while minimizing unnecessary weight.

During manufacturing, the wheel begins as a precision-cast aluminum structure. The wheel barrel is then subjected to controlled heat and pressure while rotating at high speed. This process stretches and compresses the aluminum, creating a thinner, stronger barrel with improved mechanical properties compared to conventional cast wheel construction.

Benefits of Flow Forming Technology include:

• Reduced Unsprung Weight: Lightweight construction can improve suspension responsiveness compared to heavier wheel alternatives.

• Increased Barrel Strength: Flow forming improves the mechanical properties of the aluminum wheel barrel.

• Improved Fatigue Resistance: Enhanced material properties help withstand repeated loading during demanding driving conditions.

• Greater Shock Resistance: Improved barrel strength and material characteristics provide additional durability.

• Performance-Oriented Construction: Offers advanced wheel manufacturing benefits at a more accessible price than fully forged wheels.

At approximately 20.06 pounds, the Ampliform provides a weight-conscious option for enthusiasts seeking an 18x8.5-inch performance wheel.

Ampliform Design & Fitment Considerations

The Konig Ampliform features an intricate mesh-inspired multi-spoke design that combines aggressive styling with modern performance-wheel engineering. Its Dark Metallic Graphite finish provides a sophisticated metallic appearance suitable for street, autocross, and track-focused vehicles.

The 18x8.5-inch width and +32mm offset provide a versatile configuration for vehicles with compatible wheel and tire clearance. Depending on the application, this configuration may accommodate wider performance tires than factory wheels.

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

The 72.6mm center bore must be compatible with the vehicle's hub dimensions. Vehicles with smaller hub diameters may require appropriate hub-centric rings, while vehicles with larger hubs cannot accept the wheel without a specifically approved solution.

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

Important: The Ampliform's spoke design does not guarantee clearance for every brake package. Always verify the exact wheel configuration before purchasing.

Common Reasons for Replacement

• Factory Wheel Upgrade: Replace original equipment wheels with a performance-oriented aftermarket design.

• Improved Vehicle Styling: Enhance the vehicle's appearance with aggressive mesh-inspired spokes and a premium Dark Metallic Graphite finish.

• Reduced Unsprung Weight: Upgrade from heavier factory or aftermarket wheels to a lightweight Flow Formed alternative.

• Performance Wheel and Tire Setup: Accommodate compatible performance tires for street or track applications.

• Custom Performance Builds: Complete a modified BMW or other compatible performance vehicle with premium aftermarket wheels.

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

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

Installation Notes

1. Verify Vehicle Compatibility: Confirm the 18x8.5-inch size, +32mm offset, and 5x120 bolt pattern are appropriate for your vehicle.

2. Check Hub Compatibility: The 72.6mm center bore must be compatible with the vehicle's hub diameter. Hub-centric rings may be required when the wheel bore is larger than the hub.

3. Confirm Brake Clearance: Verify adequate clearance around factory or aftermarket brake calipers, especially when using larger performance brake kits.

4. Use Proper Lug Hardware: Install compatible conical-seat lug nuts or bolts with the correct thread size, length, and engagement. Factory hardware may not be compatible.

5. Select Appropriate Tires: Choose tires approved for the 8.5-inch wheel width and compatible with the vehicle's available clearance.

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 avoid unnecessary changes to speedometer accuracy or vehicle handling characteristics.

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

9. Torque Wheel Hardware: Tighten lug nuts or bolts 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.
