Command the Road with the Motegi MR158 18x9.5 Flow Formed Wheel

Unleash the full potential of your performance vehicle with the Motegi MR158 18x9.5 wheel. This wider variant of the celebrated MR158 series is engineered to provide an aggressive stance and an increased contact patch, translating to superior grip and enhanced cornering capabilities. Crafted using state-of-the-art flow forming technology, this wheel offers a significant reduction in weight while boosting structural integrity, delivering a noticeable improvement in vehicle dynamics and responsiveness. The striking Motorsport Gold finish, complemented by a precision machined lip, ensures your vehicle makes a powerful visual statement.

Advanced Flow Formed Construction for Peak Performance

The Motegi MR158's construction is a testament to cutting-edge manufacturing. Its flow formed aluminum composition involves a specialized process where the wheel barrel is spun, heated, and stretched under high pressure. This effectively forges the aluminum, optimizing its grain structure and creating a denser, more resilient material. The result is a wheel that is both incredibly strong and remarkably lightweight, drastically reducing unsprung mass and rotational inertia. This translates to sharper steering, quicker acceleration, and more effective braking. Each wheel is rigorously tested and certified to SAE J2530, JWL, and VIA standards, guaranteeing uncompromising quality and safety.

Key Dimensions for Aggressive Fitment

This Motegi MR158 wheel is precisely engineered with the following specifications:

  • Diameter: 18 inches
  • Width: 9.5 inches
  • Bolt Pattern: 5x114.3 (5x4.5 Standard)
  • Offset: +40mm
  • Center Bore: 72.56mm
  • Load Rating: 1560 lbs (707 kg)
  • Wheel Weight: 21.9 lbs

The substantial 9.5-inch width and +40mm offset are designed for enthusiasts seeking an aggressive fitment that maximizes tire performance and provides a dominant road presence. The Motorsport Gold with Machined Lip finish offers a distinctive, high-performance aesthetic that will elevate your vehicle's overall look.
