Konig Hexaform 18X10.5 5X114.3 ET18 Gloss White Flow Formed

Flow Formed Strength in Gloss White — Konig Hexaform HF0851418W in 18x10.5 5x114.3 ET18

The Konig Hexaform HF0851418W is a flow formed aluminum wheel built in 18x10.5 with a 5x114.3 bolt pattern and ET18 offset in gloss white. Flow forming spins the barrel of the wheel under heat and pressure after casting, compressing the aluminum grain structure and producing a wheel that is significantly stronger and lighter than a comparable cast-only design. The HF0851418W brings that engineering advantage to a wide-body 10.5-inch wide fitment in a gloss white finish that commands attention at shows and on the street. Each HF0851418W is sold individually with a matching center cap included.

The 73.1mm center bore covers the widest range of 5x114.3 vehicles, and the 60-degree conical lug seat accepts standard aftermarket lug nuts without adapters. TPMS sensors mount without modification. The ET18 offset is an aggressive stance fitment verify fender, suspension, and caliper clearance before ordering for your application.

Fitment

The HF0851418W fits vehicles running a 5x114.3 bolt pattern. Due to the extreme 10.5-inch width and ET18 offset, thorough fitment verification is required before installation. Compatible platforms include:

Frequently Asked Questions

What is flow forming and how does it benefit the Konig Hexaform HF0851418W?
Flow forming (also called flow forging or rotary forging) is a manufacturing process where the barrel of the wheel is spun under heat and pressure after the initial cast. This aligns the aluminum grain structure, increasing tensile strength and reducing weight compared to a standard cast wheel of the same size. The HF0851418W uses flow formed construction for better performance than a conventional cast wheel at this width.

What tire sizes work on the Konig Hexaform HF0851418W (18x10.5)?
An 18x10.5 wheel supports tires from approximately 275 to 315 wide, depending on the desired stretch or fill. Common performance fitments include 295/35R18 and 305/35R18.

What lug nuts does the Konig Hexaform HF0851418W require?
60-degree conical seat (acorn) lug nuts in the thread pitch specific to your vehicle. Most 5x114.3 platforms use M12x1.25 or M12x1.5. Factory OEM lug nuts are not compatible.

Is the Konig Hexaform HF0851418W a good fit for the Ford Mustang S550?
The S550 Mustang runs 5x114.3 and is a compatible platform. The 10.5-inch wide, ET18 offset will sit aggressively. Fender rolling or a slight pull may be needed. Mock-up before mounting tires.

Does the Konig Hexaform HF0851418W need hub-centric rings?
The HF0851418W has a 73.1mm center bore. If your vehicle's hub bore is smaller, hub-centric rings are recommended to prevent vibration at speed.

What is the warranty on the Konig Hexaform HF0851418W?
Konig backs the HF0851418W with a lifetime structural warranty and a 1-year finish warranty to the original purchaser, covering defects in materials and workmanship under normal use.

Will the Konig Hexaform HF0851418W fit Brembo calipers on the Nissan 370Z?
Caliper clearance on a 10.5-inch wide ET18 wheel must be verified by mocking up the wheel before tire mounting. Most 18-inch wheels clear the 370Z Brembo Sport package, but the ET18 offset moves the wheel outboard significantly. Always measure spoke-to-caliper clearance with a spacer or physical mock-up.

Is the Konig Hexaform HF0851418W TPMS compatible?
Yes. The HF0851418W is compatible with factory-style TPMS sensors. Have your tire shop retain the OEM sensors during installation.

Installation Notes

The HF0851418W is an extremely wide, low-offset wheel. Always verify fender, suspension, and brake caliper clearance before mounting tires. Torque lug nuts to the vehicle manufacturer's specification in a star pattern using a calibrated torque wrench. Re-torque after the first 25 to 50 miles. Do not use an impact wrench for final torque.
