Will these springs make my car ride too stiff?

AST springs are designed with a progressive rate to maintain a comfortable ride similar to OEM. They aim to lower your car's center of gravity without sacrificing too much comfort.

Do these springs come with new bump stops or perches?

The manufacturer description only states that the springs themselves are included. It's recommended to inspect your original bump stops and perches during installation and replace them if worn.

What is covered by the lifetime warranty?

The lifetime warranty covers the springs against breaking. It's a good assurance that the product is built to last under normal driving conditions.
