Before ordering a spacer kit, I suggest that you measure the amount of lift you want.
I have made some gauges that can help you decide the correct spacers for you. The price to borrow them is £3.25 – this covers the postage to a UK address, return postage and eBay/PayPal fees. The price off-eBay is £2.30. The gauges can be found on my eBay page.
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.
