My only experience is stubbing my 53 3100 with a Nova subframe. What I learned was the mating location determines the ride height. Mine came out way lower than I expected, but the slammed look kinda grew on me. What I know about IFS is that their primary purpose is to lower the vehicle. So with that in mind, why not "space" the location of the IFS so it raises the vehicle to stock height? Just my 2 cents.
