Product Description

Steeda Performance
Lower your 2015-2017 Mustang EcoBoost without sacrificing ride quality with Steeda's progressive rate Sport springs! These EcoBoost springs lower your car to optimize the center of gravity and create a drastic improvement in handling and nose dive reduction while maintaining a great ride quality. Progressive rate springs increase in rate as the body rolls to prevent excessive body roll that the factory springs produce. This also leads to sharper steering response and improved stability. Steeda engineers their springs in house using advanced proprietary CAD data and exclusive 3D modeling to create a suspension system that is second to none. This kit will work on both fastback and convertible Mustangs.

    Had these Steeda progressive sport springs installed by a local shop, ride is much more compliant over rough surfaces and the 1" drop gives the car a meaner look for sure.

    Yes, I would recommend this item to a friend!
