What does single adjustable mean?

Single adjustable coil-overs allow you to adjust both rebound and compression damping with one knob. This is simpler than a double-adjustable setup, where rebound and compression are adjusted separately. Single adjustables are a good choice for street cars and weekend racers who want improved handling without the complexity of independent adjustments.

What spring rate should I choose?

Spring rate is a matter of personal preference and intended use. A stiffer spring rate (higher lbs/in number) will provide more responsive handling and less body roll, but will also transmit more road imperfections to the cabin. A softer spring rate will be more comfortable for street driving, but may result in more body roll in corners.

Do these coil-overs require any special tools to install?

No special tools are required for installation, but you will need basic hand tools such as wrenches, sockets, and a torque wrench. Refer to the manufacturer's installation instructions for specific torque specifications and procedures. It is always a good idea to have a professional mechanic install coil-overs if you are not comfortable working on your car's suspension.
