Phresh, it's not just AWD cars (though it is more likely since the boot moves more when the wheels turn). But in any case, when you lower your car, you change the angle of the boot signifantly, especially when you slam it. This causes it to flex more than it needs to since when you slam it, you're essentially extending the boot past it's normal range of movement (or damn close to it). Then when you hit a bump, it causes the wheel to push further into the fender which results in more flex. Eventually that CV boot can't take it and it tears. Unfortunately grime then gets in and there goes your joint.
The same can be said that the axle is meeting up with the joint at an extreme angle which also causes extra stress though you're more likely to tear the boot before that anyway. Your best option is to not lower it at all. But this is CL so that's not going to happen haha! Just try to keep the joint as straight as possible. The 25" from floor to fender minimum is a good general reference. Just make sure to periodically check your boots for any leaks. Once it tears, prepare yourself for a new boot and joint soon
