Will these springs make my M3 ride too stiff?

These AST springs use a progressive rate. This means they offer a comfortable ride during normal driving but get stiffer when you need more support during cornering or hard braking.

Do I need any special tools to install these springs?

Installation requires a spring compressor to safely remove and install the springs. It's recommended to consult a service manual or a professional mechanic for the correct procedure.

What does the lifetime warranty cover?

The manufacturer provides a lifetime warranty against the springs breaking. This covers defects in materials or workmanship that lead to the spring failing.

About this part

Product Details

25mm front and 25mm rear drop. AST Lowering Springs replace your stock springs to lower your 1988-1990 BMW M3's center of gravity. They're made on Wafios coiling machines for a consistent spring rate.

These springs are cold-coiled and use a progressive design. This means they get stiffer as they compress, helping to balance a lower ride height with everyday comfort.
