Whenever you raise the height, the toe-in increases. I found that out when I wore out a pair of new tires in a 100 mi trip after adjusting the front height. By the same token, as the suspension ages and sags, the steering goes to toe out, which makes the car wander.
I got tired of going to alignment shops and paying big bucks for them to maybe do nothing or fuss about "not in the computer". I started adjusting toe-in myself using a tape measure front to back, which isn't hard if you have tires with straight channels (search the web). My cars drive perfectly straight, the steering wheel is clocked correct, and I have no abnormal tire wear. If tight linkage, you can adjust to 1/16" toe-in. Toe-in just compensates for play in the linkage that moves the front wheels on a RWD back (and out). Opposite on FWD since the front wheels pull. Ideally, the front wheels are exactly parallel when driving on either.
