I've seen H&R's freshly installed on AGX's and they have appeared to run just a hair over 1.5". If you want to play it safe, consider the Eibachs, they only lower about an inch. Dont waste your time with the Tein's. I have the Tein soft springs with version 5 struts and HATE them! Opie, used to run Agx's with the Tein's and just replaced them with the Eibachs.
