What is the specific drop height for these springs?

These AST lowering springs are designed to provide a 50mm drop in the front and a 40mm drop in the rear for the specified BMW 3 Series models.

What does 'progressive design' mean for these springs?

A progressive spring design means the spring rate changes as it compresses. This allows for a softer initial ride, similar to OEM, but stiffens up under load for improved handling and reduced body roll during spirited driving.

What does the lifetime warranty against breaking cover?

The lifetime warranty against breaking covers the springs themselves against failure due to breakage for as long as you own the vehicle. It ensures peace of mind for the longevity of the product.
