I never understood this. Downsizing brakes is the last thing I'd to to an LR3/4, especially as the tire size starts to increase and the lbs start to stack on. Just get a set of 18" Compomotives that clear the larger brakes. If you can afford the aftermarket front/rear bumpers, racks and sliders, then you can afford the correct wheels (or just forego one of the aforementioned options). My LR3 with (5) 35"s, a rack, sliders and a steel front bumper needs MORE brakes, not less. I can't imagine driving something that weighs just as much and has an additional 80+hp with less/equivalent brakes. Just one man's opinion though...
