About this part

Product Details

30mm front and 30mm rear drop. AST Lowering Springs replace your stock springs to lower your BMW 4 Series Gran Coupe. This reduces the center of gravity for better handling without sacrificing too much ride comfort.

These springs are cold-coiled on Wafios machines, a popular choice for spring manufacturing. They are designed specifically for your vehicle to ensure a proper fit and function.
