As soon as the LE ADS was installed the difference was noticed right away. The suspension immediately felt more rigid and feels like its reacting to the road faster. In +R mode it is very stiff and Would be comparable to going up three clicks on a an adjustable coilover damping from before it was installed. Sport mode is a good daily driver mode, is comfortable to use and stops you from constantly bouncing in the seat like +R mode does. Comfort mode is quite soft and squishy. The small bumps are absorbed but the bigger dips and bumps are a little more firm as the suspension gets compressed and has time to react to the road.
It is a great upgrade if you are looking to drive the car hard as it feels planted at high speed and at low speed its a little uncomfortably stiff. I would say it is a worth while upgrade as it only takes around 10 mins to install.
