Interesting, I'll look into it further. 2" lifts are generally the default replacement suspension height because they tend not to cause any issues. I was under the impression that Land Rover radius arms are very similar in dimensions to Patrol arms, and therefore should be fine with a 2" lift.
I fitted aftermarket radius arms to the Cruiser with the 3" lift, however this was more for guard clearance than castor correction. At least Land Rover arms seem to be significantly cheaper than those.
