Optimize Your Stance with Eibach Pro-Spacers

Achieve the perfect wheel fitment and improved handling characteristics with the Eibach Pro-Spacer System. Specifically engineered for the 1990-2005 Mazda Miata and select MX-3 models, these 15mm spacers provide a wider track width, resulting in increased stability and a more aggressive aesthetic. Eibach is world-renowned for precision manufacturing, ensuring your wheel assembly remains perfectly balanced.

Technical Specifications

  • Thickness: 15mm per side
  • Bolt Pattern: 4x100
  • Hub Bore: 54.1mm
  • Material: High-strength, lightweight aluminum alloy
  • Compatibility: Designed for specific Mazda hub configurations

These spacers are designed to integrate seamlessly with your factory or aftermarket wheels. By pushing the wheels outward, you improve the vehicle's cornering stability and create a flush, performance-oriented look. Please note that proper installation requires verification of your vehicle's specific wheel stud knurl diameter (typically 14.9mm for these applications). Always ensure that your wheel studs are compatible with the spacer thickness to maintain safe thread engagement. Whether you are preparing for a track day or simply want to improve the daily driving dynamics of your Miata, Eibach spacers are the gold standard in wheel accessories. Elevate your driving experience with high-quality components from GGCRACING.
