Wow.. ever since I got these installed it seems I've been answering so many questions about theses springs (heh QWK)
Anyways, they are rated to drop 1.3" rear and 1.5" front. If you want to see what they look like go here:

I highly recommend them if you want to go lower than TRD but not too low. I have the TRD kit and I don't scrape if I drive carefully.
