Before ordering a spacer kit, I suggest that you measure the amount of lift you want.
Here is a link to the discussion I had while I was developing the spacers - zRoadster.net
Below is a video that I made showing how to fit the spacers. At the end of the video, you can see the difference the spacers make to the tilt of the seat.
