      Description

      Enhanced Suspension Performance. The Ford Performance Lowering B-Springs significantly lower vehicle height, improving handling and road feel for your Mustang. These springs are designed for enthusiasts seeking better cornering precision and a more aggressive stance. They replace the factory springs and provide responsive handling ideal for street driving and occasional track use.
