this is the SLP eibach kit, not the prokit/sportlines. It's not supposed to be more than a 1" drop
I had the same setup at one point but I sold the front springs in favor of something lower, not knowing anything about valving/spring rates. I don't know if my setup was worn out by the time I got it (bought it used), but one thing I did notice was the rear liked to jump when I hit bumps around corners, which wasn't the most stable feeling. I replaced the rear bilsteins with Koni 3rd gens which helped a lot and eventually replaced the rear springs with something softer also. It did handle pretty well though, was a HUGE upgrade from decarbons. The first time I got on the highway the car felt totally different, I never noticed the floaty/bouncy feeling until I had the new setup on it and it was solid.
looks good!
