The AST Lowering Springs are engineered to provide a precise lowering solution for BMW 3 6CYL. and 320D models produced between 10/1999 and 09/2005.

These springs are a direct replacement for the original equipment, developed specifically for each vehicle to maintain optimal suspension geometry and performance. Their progressive coil design balances lowering height with ride quality, making them suitable for both everyday driving and spirited performance. The use of premium materials and precise manufacturing processes guarantees long-lasting reliability, supported by a lifetime warranty against breaking.

AST’s extensive experience and commitment to quality have resulted in a product compatible with over 2500 vehicle models from 1966 to the present, reflecting their adaptability and engineering excellence. This set is ideal for drivers seeking to improve their BMW’s driving dynamics while retaining comfort and safety standards.
