Rucas are very easy and cheap and its a very good idea. I also have the ebay specials on my S14 and they hold up. I run a staggered settup and have some expensive tires so its best IMO to run someone sane camber angles

Still at about -1* is fine for me, i still get great turn in and dont oversteer to much anymore (which is prolly do to the tires anyway).
