progressive rate springs means that the spring rate changes throughout the compression of the spring. this is typically done so that the springs tend to react more casually when drving less aggressively, yet will provide a higher, more responsive spring rate, when the car is pushed harder.
linear rate means that the springs have a single spring rate, no matter where in the compression range. this is typically better for more performance-minded suspension setups, because the shocks can be appropriately valved in accordance with the provided spring rate.
- with progressive rate springs, since the rate changes, it becomes more difficult to properly valve the shocks/dampers to compliment the spring rate.
