What does 'single adjustable' mean?

Single adjustable means one knob controls both rebound and compression damping. This simplifies tuning, as you don't have to adjust each independently. It's a good setup for street cars and weekend racers.

Do I need any special tools to install this kit?

You'll need basic hand tools, plus a spring compressor to safely install the coil springs. Refer to the manufacturer's instructions for specific tool recommendations and torque specs.

What spring rate should I choose?

The 325 lbs/in spring rate is a good starting point for many GM vehicles. However, your ideal spring rate depends on your car's weight, intended use, and personal preference. Consider your vehicle's specific needs when selecting a spring rate.
