        Hi Anon, glad to help you! Variable rate coil springs are meant to maintain the proper attitude of a car on the road while absorbing some of the shocks and bumps the car goes through. However, variable rate coil springs are designed to adjust to the weight of the car. So while on a car using regular springs, the more weight you load in it the lower it will sit, on a variable rate coil spring car, the springs will have two compress stages. So while the car is empty or there are only a few passengers in, it will sit high and it will absorb every shock in the road. Once you begin loading the car, the wide coils of the spring are compressed, the car sits lower and is more stable, and the suspension feels more rigid but it is still there doing its job.
