Finally got around to putting my Eibach springs into my SR+. I'm downloading the pics from my phone now, but overall here's my first take on driving with them.
My first drive was on some surface streets, including going over railroad tracks, and then getting onto the freeway and "going with the flow of traffic" around 80-90 mph. Overall, the car feels a bit smoother driving it on the 20" wheels than before. With the stock springs, it felt tighter driving on a bumpy road. Now it feels smoother, and definitely not "floaty" or anything like that. Still feels very stable, and even more stable now when I jerked the steering wheel a couple of times to maneuver around some obstacles (one be at high speed on the freeway).
Overall, the car looks & feels great. I didn't cut the bump stops, and I haven't had any shock travel issues yet. Visually, the car looks lower with the fender gap nearly gone, and it obviously looks lowered. Before, I had a 4-5 finger gap all around, and now I have a 2 finger gap all around. Since I'm using bigger 20" wheels, the ground clearance in the front & back are pretty much the same as what they were before with the stock 18" Aero wheels, so I didn't lose any clearance there.
