This is just a factoid that may interest some people. I've always thought that the jounce travel of the rear axle was measured from the top of the axle tube to the rubber jounce bumper on each side. However, some snooping around back there revealed that, except for one wheel bumps, the nose of the axle housing hits the AXLE SNUBBER (in the tunnel) about an inch BEFORE the tubes hit the jounce bumpers. I was surprised! This means that if the rear of the car is lowered a bit and you have ,say, 2 inches from the axle tube to the bumpers on each side, you really only have 1 inch of suspension travel. It's something to chew on.
