The AST Lowering Springs for the BMW 4 Series F36 are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and shot peening for fatigue resistance. The powder-coated finish ensures long-lasting corrosion resistance, making these springs a reliable upgrade for enthusiasts seeking improved ride quality. Featuring progressive rates on most vehicles, they provide a balanced combination of comfort and performance, especially during aggressive driving or cornering.

Designed specifically for the 2014 and newer BMW 4 Series F36 models, these springs are compatible with vehicles equipped with Electronic Damping Control (EDC). They serve as a direct replacement for stock springs, lowering the ride height by 25mm at the front and 20mm at the rear, enhancing the vehicle’s stance and handling dynamics. Installation is straightforward for those familiar with suspension upgrades, and the springs are suitable for street and spirited driving. These springs are ideal for drivers seeking a lowered, sportier look without sacrificing daily comfort, and they are compatible with a range of F36 chassis configurations.

Overview

AST Lowering Springs for the 2014+ BMW 4 Series (F36) are manufactured from a premium high tensile chromium-silicone wire which is handpicked by AST engineers for its quality and metal consistency.
