Product Description

The AST Suspension Lowering Springs – BMW G80 M3 / G82 M4 are high-performance progressive-rate coil springs designed to lower your BMW G8x (including Competition and xDrive variants) for enhanced handling, reduced body roll, and a sharper, more aggressive stance while retaining comfortable street performance. Built from premium high-tensile chromium-silicone wire and manufactured with precision winding and heat treatment, these springs deliver a stable, consistent drop that improves response and cornering balance. They work with the vehicle’s original damping system and provide a direct replacement for factory springs.
