Eibach PRO-SPACER 20mm Rear Wheel Spacers, 5x4.5 Bolt Pattern, 70.5mm Hub, Ford Mustang | S90-4-20-017

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. When using the wheelspacers you have to verify that the wheels being used have suitable cut-outs to take up the original bolts. Without these cut-outs it is necessary to use the delivered studs in exchange to the original studs!

• Precision Engineered Hub-Centric - for Perfect Fit and Wheel Balance.
• Kit Includes 2 Spacers and all necessary mounting hardware.
• Made from High-Strength Aircraft-Aluminum Alloy.
• Reduced Weight Compared to Steel Wheel Spacers.
• Widen Your Stance - For Better Handling.

The Eibach PRO-SPACER S90-4-20-017 rear wheel spacer kit is designed for select 2010–2014 Ford Mustang applications. These hub-centric spacers widen the vehicle’s track width to improve stance, support more confident handling, and provide additional clearance for compatible wheel and tire combinations. The 5x4.5-inch bolt pattern and 70.5mm hub center are engineered for proper wheel alignment and balanced installation when matched to the vehicle and wheels.

Manufactured from high-strength aircraft-aluminum alloy, Eibach PRO-SPACER wheel spacers offer reduced weight compared with conventional steel spacers while maintaining durable performance for street and off-road use. The 20mm spacing per wheel helps create a wider, more aggressive appearance and may reduce body roll by lowering the vehicle’s effective center of gravity. Always confirm wheel, tire, suspension, and brake-clearance requirements before installation.

Before using this Eibach spacer kit, verify that the selected wheels have suitable cutouts to accommodate the original wheel studs or bolts. If the wheels do not provide sufficient clearance, the supplied studs must be installed in place of the original studs. Professional installation and proper torque procedures are recommended. Fitment includes select 2010, 2011, 2012, 2013, and 2014 Ford Mustang models; confirm the exact application before ordering.
