Yea I live in an apt complex that has around 5 speed bumps b4 I get to my parking spot. It is a B*tch, but if you take them at an angle it'll be fine. I def say don't go crazy and lower it 2" or anything.
I say lowering springs next yo. Ride would look even more sick! I know you have the gears all lined up and ready to be put on. But I just ordered my H&Rs today and hell we can meet up and put them on in week or so. Then do yours later.
