How much will these springs lower my BMW E30?

These AST lowering springs are designed to lower your vehicle by approximately 40mm in the front and 40mm in the rear. This change can improve handling by reducing the vehicle's center of gravity.

Do these springs come with new bump stops or perches?

The manufacturer description only mentions the springs themselves. It is recommended to inspect your original bump stops and perches during installation and replace them if they show signs of wear.

What is the warranty on these AST lowering springs?

AST provides a lifetime warranty against breaking for these lowering springs. This covers defects in material or workmanship that lead to the spring breaking.
