RE: steering guards/HD arms - if I went for HD arms (I am also looking to do one or the other!), surely the force that would normally be absorbed by the arm bending will be transferred to another component somewhere, or the bushes, etc? I must admit, I was going for a sump guard - my biggest reservation is actually that they tend to catch oil leaks, so you don't notice them like you would without when a car is parked up overnight! And lets be honest, oil leaks are an issue for us LR owners...
Sorry...but yeah! Range Rover went up it no problem, not sure what all the fuss was about?
