I run 7.50's on my disco and have HD normal height springs, I'm using Defender steel wheels as they Had 15mm better offset than my alloys so I didn't need to alter the steering stops, and i need to do a camel cut because I do scrape the rear arch if i articulate to much, but all vechiles are different there are alot of varibles conditon of springs vechile loading etc, if you have them give it a go see if it works, or see if somebody will let you try theirs.
