There's an instruction booklet that comes with the kit. It's in Japanese but the pics are pretty helpful. I'd recommend you get a FSM if you haven't done a suspension swap before.
When you jack up the car try and get the whole car off the ground. If you can only do one side make sure you do either the front or the back at the same time. The front is especially important because the sway bar is a real bitch to work with if you only jack up one side.
One final tip. When you take the sturts apart (with spring compressors) make sure you put the peices on in exactly the same order you took them off.
