Eibach PRO-SPACER 15mm Wheel Spacer Kit with Extended Studs for Mazda 3 and Mazda 6

Eibach PRO-SPACER wheel spacers for cars, trucks, and UTVs are the ideal solution for improving stability and handling, increasing clearance for larger tires, and giving your vehicle that aggressive and commanding presence. By widening the vehicle's track width, wheel spacers lower the center of gravity, reduce body roll, and ultimately enhance capability of your vehicle on- or off-road. Mazda / Nissan / Subaru have various wheel studs that are dependent on the model, axle or year manufactured. Before ordering, please check the knurl diameter of the original wheel studs on both axles. In our kits, we include wheel studs with a knurl diameter of 13mm.

• Precision Engineered Hub-Centric - for Perfect Fit and Wheel Balance.
• Made from High-Strength Aircraft-Aluminum Alloy.
• Reduced Weight Compared to Steel Wheel Spacers.
• Widen Your Stance - For Better Handling.

The Eibach PRO-SPACER wheel spacer kit is engineered to improve vehicle stance, handling, and wheel clearance on compatible Mazda applications. By widening the track width, these spacers can help reduce body roll, improve cornering stability, and provide additional room for larger tires or wheels. The kit includes extended wheel studs designed for applications requiring a 13mm knurl diameter.

Each spacer is precision engineered with a hub-centric design to support accurate wheel positioning and balanced operation. The high-strength aircraft-aluminum alloy construction helps reduce weight compared with traditional steel spacers while providing durable performance for street and performance driving. Proper installation requires confirming the original wheel-stud knurl diameter on both axles, as Mazda, Nissan, and Subaru applications may use different stud specifications depending on the model, axle, or production year.

This Eibach PRO-SPACER kit is listed for select 2004–2009 Mazda 3 applications and is also identified for the 2003–2008 Mazda 6 with the 2.3L engine. Verify vehicle-specific fitment, wheel-stud requirements, wheel clearance, and applicable installation procedures before ordering. Professional installation and re-torquing after initial driving are recommended for safe, reliable performance.
