You do not want to lincon lock a daily driver, on icy roads you will never stay strait, your tires will hop on every corner and your tires will ware out fast. If you lincon lock the front you would have to unlock at least 1 hub every time you want to turn and I don't think the CV axles would hold up very well. I tried to stiffen up the factory rear limited slip by putting a spacer under each spring. I don't have it installed in the Kia yet but when I do I will post the results.
