Eibach PRO-SPACER 15mm Wheel Spacers, 4x100 Bolt Pattern, 54.1mm Hub for Mazda Miata

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 dependant 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 14.9mm (14.3mm for Subaru). Other Knurl diameter sizes need to be indicated when ordering!

• 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 System, part number S90-6-15-010, is designed for select Mazda Miata applications using a 4x100 bolt pattern and 54.1mm hub. These hub-centric wheel spacers widen the vehicle’s track width to improve stance, handling, and wheel clearance. The 15mm spacing per side can help accommodate larger tires or wheels while providing a more aggressive appearance for street and performance applications.

Each spacer is precision engineered for a hub-centric fit, helping maintain proper wheel balance and reduce the potential for vibration when installed with compatible wheels and hardware. Constructed from high-strength aircraft-grade aluminum alloy, the Eibach PRO-SPACER design reduces weight compared with traditional steel spacers while providing durable performance. By widening the stance, the system can help reduce body roll and improve stability during cornering or off-road use.

Important fitment note: Mazda, Nissan, and Subaru vehicles may use different wheel-stud knurl diameters depending on the model, axle, or production year. This kit includes wheel studs with a 14.9mm knurl diameter. Verify the original wheel-stud knurl diameter on both axles before ordering; other knurl diameters must be specified when ordering.
