Classic 14-Inch Vintage Style: Featuring a universal 350mm (14-inch) diameter, this steering wheel combines timeless wooden elegance with a sporty racing feel. It’s the perfect interior upgrade for classic cars, muscle cars, or JDM projects, adding a touch of sophisticated craftsmanship to your cockpit. Premium Matte Black Stainless Steel Spokes: Engineered for maximum strength and longevity, the 3-spoke design is crafted from high-grade stainless steel with a sleek matte black oxidized finish. This heavy-duty construction is heat-resistant, anti-corrosion, and built to withstand the rigors of daily driving. Ergonomic Grip with Finger Grooves: Designed with the driver in mind, the back of the wooden rim features smooth, integrated finger notches. This ergonomic "finger groove" design ensures a secure, non-slip hold and exceptional hand comfort, reducing fatigue during long cruises or spirited driving. Superior Durability & Finish: The real wood rim is treated with a high-quality coating that is smooth to the touch and resistant to temperature changes. Unlike plastic alternatives, our wooden steering wheel offers a premium tactile experience that stays cool in the summer and warm in the winter. Universal 6-Bolt Fitment: This steering wheel features a standard 70mm 6-bolt pattern, compatible with most aftermarket hub adapters (e.g., NRG, MOMO, Sparco). [Please Note: Hub Adapter/Boss Kit is required for installation and is NOT included with this product.] Hiracing 14inch Universal Classic Wood Grain Steering Wheel Brushed 3 Spoke 1.5inch Depth Racing Steering Wheel with Horn Button 6 bolts
