Are you using the rear shock bolts? I need ef ones, as mine were too short, and I had to buy some at lowes lol, and they are too long. Also how did your old coils ride in your ef ( I never rode in it), the rears are pimp in my car, but the fronts are beginning to be murder lol.

Al;so be careful heard on my forum, anything over 450 might require revalving with the konis, and low ride height might require them to be shortened too.
