Will these springs make my BMW 640i ride too stiff?

AST springs use a progressive design. This means they are softer on initial compression for comfort, and get stiffer as they compress further to improve performance during harder driving.

Do I need any special tools to install these lowering springs?

Installation typically requires spring compressors and other standard suspension tools. Refer to the manufacturer's installation instructions for a complete list of tools and procedures.

What is the warranty on these AST lowering springs?

AST backs these springs with a lifetime warranty against breaking. This covers defects in materials and workmanship for as long as you own the vehicle.
