Lesser Known 4th gen Prelude Aero Kits

[94PreludeJDM]

For the most part, I'm not a big fan of any of the kits for the 4th gen prelude, with the exception of the Hiro kit. A lot of the aero kits are nice though, and I was looking at http://www.preludecrazy.com/gallery/exterior/index.php which has a lot of kits I hadn't seen before (go to exterior, I think the page automatically loads to hoods and bonnets). I found some of the kits, but two that I liked and couldn't find were the KC Aerodynamics Design kit and the SPi kit, at least not in English. I searched google like crazy, as well as nearly every body kit site I know, but couldn't turn anything up...anyone have any idea where to find them?
