2014+ BMW M4 Convertible 3.0L Turbocharged

Part #: ASTLS-19-009

Overview

Upgrade your BMW M4 Convertible with the AST Lowering Springs, designed to enhance both the aesthetics and handling of your vehicle. These high-quality springs are engineered specifically for the 2014 and newer models, providing a tailored fit that maintains your car's factory reliability while delivering a more aggressive stance. Whether you're a spirited driver seeking improved cornering or an enthusiast looking to refine your vehicle's appearance, these springs are an excellent choice.

AST suspension lowering springs are crafted to lower your M4's ride height by approximately 20mm to 60mm, giving your convertible a sportier, more planted look.

Designed with a focus on maintaining ride comfort, these springs balance performance gains with everyday drivability, making them suitable for both street and spirited driving.
