I have been all over the place and I have looked at a lot of set ups. I am finally getting the chance to lower my 07 GT/CS. However I am a little concerned putting both the front and rear springs on because the front already sits pretty low on the California Special. Anyone here lower theirs all the way around or did you just do the rears? Have any pictures? How is it over speed bumps as that is pretty much what it is like going over getting in my drive way? As always thanks for the responses.
