Ok. I have Sportline springs that I'm about to put on my car. I don't want to get them on there and get the car aligned and then realize that I should have put the Pro kit on it. I do have to drive it, everyday. What springs do you have and how much did they drop your car? (From the top of the fender lip to the ground.) Do you have any problems with obstacles such as speedbumps, driveway aprons, etc. I would really like to focus on the Sportlines, Pro's and possibly FRPP "C" springs.
