If you get hold of a couple 25kg bags of sand and put them in the front boot this will help to bed the new spring in, I left them in when i had mine tracked. If the silent blocks at the end of the spring needed to be pressed in and are tight you need to slacken the eye bolts, move the car up and down to settle the suspension then tighten them up while the wheels are on level ground, as Ralph mentioned. if you pushed them in by hand they will seat them selves.
