What is there really that can be done to "ruin" the lr3/4? What I'm getting at is there aren't really that many extreme modifications even available, therefor you'd have to try pretty hard to ruin it.
I suppose these bump stop extension are the first real crazy mod that could fall into the scope of your statement.
I was never a fan of the "rod mod" precisely because of what you just said. I did install the LLAMS electronic interface though because it sure is nice to fit into a garage when needed or gain more lift with a simple dial turn while highway driving is still kept at the factory height.
The LR3/4 does not need much, like I said earlier. It will never be a rock crawler and I could never see bouncing that heavy lug through what we did at the Pearls Pond days of MAR. It's not a great deep snow ride, either. It's more of a
jack of all trades, master of none. The LR3/4 will preform better than most other 4wd's on the market in the same category, but it does not really excel at anything, even if you jack it up and put 35's under it.
I towed a boat about 3 weeks ago with a V8 4-runner 120 miles each way. By far the LR3, even with a 6cyl, tows better. And that's what I like about the LR3/4's - they're versatile. They're not great off-road and I don't think that sets the bar for a vehicle - even if Land Rover's heritage may sway that way. But I can jump into the LR3 and be comfortable camping in the woods, towing, going out to dinner, or driving across the country.
Of course, I like the woods. I live in the Shenandoah Valley of Virginia so naturally a few mods to the Rover are favorable. But the LR3/4 does not need much to improve upon what is already offered from the factory. I'm not going to be doing the Camel Trophy in the LR3 and neither is anyone else. So making your LR3/4 bullet proof is silly to me. Bumper, winch, under body protection and maybe a roof rack and auxiliary lighting is all the LR3/4 really needs to improve its versatility off-pavement. If you were a fisherman in OBX, perhaps your requirements would differ.
What happens, though, is people get bored. They start adding lift rods, big tires, double spare tire carriers, swing away Jerry Can racks, motorized remote control spotlights, the biggest LED light bar they can find.... They fuck the truck up. Just because you can does not mean you should. I mean really, what benefit do 35" tires serve on an LR3/4? Why do you need three spare tires? It's like putting a 5" lift on a D1.
