The upper and lower stock control arms are different lengths to get that camber change. The only way to lessen it is to lengthen the upper control arm or shorten the bottom one, which would lead to a whole lot of issues beyond camber change. If you lengthen the uppers, you have to move the attaching points of the inner ends in the same amount you lengthen the A arm. Your best bet is to limit front travel to about four inch, and make a soft stop if you don't use the factory one. You can also start with the front end lower if there is room.
