17×7.5J Flow-Formed Alloy Wheel 4×100 ET38 with Dual Finish Options

1. Product Overview

The KU-FV-10-002 is a 17×7.5J flow-formed aluminum alloy wheel featuring a 4×100 bolt pattern, ET38 offset and 73.1 mm center bore. Its three-dimensional open multi-spoke design is available in Hyper Black and FHB Silver finishes for different vehicle styling requirements.

This model is intended for aftermarket wheel distributors, tuning workshops, vehicle-accessory retailers and compatible passenger-car customization projects.

2. Flow-Formed Barrel Design

• Flow-Forming Process: The rim barrel is shaped and extended through controlled spinning after the initial forming stage.

• Optimized Material Distribution: The process is designed to place material efficiently through the barrel section while controlling wheel mass.

• Aluminum Alloy Construction: Combines structural performance, corrosion resistance and lower weight than many conventional steel-wheel designs.

• Unsprung-Mass Management: An appropriately selected aluminum wheel can support responsive steering and suspension movement without changing the vehicle’s basic geometry.

3. Open Multi-Spoke Styling

• Three-Dimensional Spokes: The layered multi-spoke arrangement creates depth and a technical appearance.

• Open Spoke Layout: Provides visual exposure around the brake assembly and allows air to circulate through the wheel openings.

• Hyper Black Finish: Offers a dark metallic appearance suited to both understated and performance-oriented vehicle designs.

• FHB Silver Finish: Provides a brighter metallic appearance for buyers seeking a clean and refined wheel style.

• Protective Coating: Helps resist oxidation, sunlight exposure and routine road contamination under normal driving conditions.

4. Precision-Machined Mounting Features

• CNC-Machined Bolt Openings: Supports consistent dimensions across the four wheel-fastener positions.

• CNC-Machined Center Bore: Provides a controlled mounting surface for compatible vehicle hubs or correctly selected hub-centric rings.

• ET38 Offset: Positions the wheel mounting face according to the specified lateral geometry.

• 4×100 Bolt Pattern: Uses four fastener holes arranged on a 100 mm pitch circle.

5. Distributor and Installation Guidance

• The two available finishes allow distributors to serve different aftermarket styling preferences with one wheel specification.

• Confirm vehicle compatibility using the rim diameter, width, offset, bolt pattern and center bore.

• Verify the required wheel-load rating, brake-caliper clearance, suspension clearance and fender clearance before installation.

• Confirm the correct wheel-fastener thread and bolt-seat profile for the vehicle and wheel.

• Tires should be mounted and dynamically balanced by a qualified wheel or tire workshop.

• Tighten the fasteners to the applicable torque specification and recheck them after the initial driving distance.
