It'll be beneficial to remove the 12mm bolt holding the wiring bracket to get to some of the nuts on the driver side, along with the ability to remove the coils. Also, at the back of the drivers side, (closest to the steering wheel) The wiring will be clipped into a bracket, try and squeeze it and pull it out, it'll give you the ability to pull the coils comfortably. Essentially the driver side is horrible, but theres lots of little things that you can move to make life easier.
