I just redid my front end & it lowered from 27" in the front to 26". That is using the center of the wheel as the plumline, from the ground (level ground that is) to the bottom of the wheel well trim.
I wouldn't have minded a 1/2" drop, but this is too much. My trim is actually below the top of my tire (barely). Nothing touches when I turn the wheel too sharp, but it is lower than I wanted it. I was hoping that I had some sag in my stock springs with 100K on them & the new Hotchkis wouldn't drop me too much, but it dropped 1" just as advertised.
I am going to do my rears w/new shocks also, in a month or two. I just found out that we have a spring shop here in Ytown that will make springs to order so I am going to check them out tomorrow, hopefully.
