Replying to Topic 'suspension'
We have those. We call them "speed bumps". It depends. With Eibach springs the ride wil have very little travel and you shouldn't have a problem. If you decide to go with a variable coilover system where you can adjust the height you want it dropped, you will have very little [if any lol] travel in your suspension. I don't think you have to worry about these. Just take your time over them. Don't fly across them but you don't need to crawl either. I'd suggest measuring how high they make these speedbumps and allow a tiny bit for travel of the suspension. Probably .3 of an inch. As for the springs they won't lower the car enough to be a problem. Most Eibach kits, as I had on mine, will lower a car about 1.5 inches. No problems there.
Then of course there is your method to driving. If you think the bottom might scrape over something unusually high then take it diagonally. One wheel at a time. Sometimes with lowering it requires a little more care given to driving. A small sacrifice for what looks SO much better.
