The front springs have a rate of 342lbs while the rear is a progressive spring.
The reason KW has lower spring rates than most aftermarket coilover companies is that KW is one of only three companies in the world that can tune the shocks they way we do. The other two are Penske and Olins, and both of these companies only build suspension for race vehicles to my knowledge, while KW builds both street and race only applications.
KW tunes the high speed and the slow speed of the piston separately. What this means is that when you hit a speed bump, a bumpy road, ect ect, the piston inside the shock is at its “fast speed”. This area is tuned very close to a stock system in a KW shock, which means great comfort for the driver. When coming into a corner, or breaking, the piston inside the shock is in its “slow speed”. This range is tuned to be far more aggressive than stock. This means that you get both a comfortable ride, and great handling. Other features of a KW system are the stainless steel construction and independent compression and rebound adjustability on the variant 3 systems.
I’m sure you’ve all had a suspension with really high spring rates. The purpose of this was to get better handling without real shock tuning involved, because until about ten years ago shock tuning technology just wasn’t available. Because we can tune our shocks, a high spring rate is not something we need, as this will only damage performance and comfort in the end. A good real world example of this is watching GT racing. Ever seen a car coming around the corner with two wheels off the ground? Because the shock is so stiff and spring rates are so high, they can’t keep both wheels on the ground, and the suspension can no longer do its job properly on any uneven surface. It may look cool, but who has better traction, they guy with two wheels on the ground or the car with all four?
