What is the spring rate of these coil-overs?

These coil-overs come with 400 lb/in springs. This means it takes 400 pounds of force to compress the spring one inch.

What kind of adjustments can I make with these coil-overs?

These coil-overs allow you to adjust both ride height and damping. Ride height adjustment lets you fine-tune your car's stance, while damping adjustment lets you control the firmness of the suspension.

Are any other parts needed for installation?
