Mark - More washers under the front camberlink ballstud will dull initial turn-in slightly and give slightly more on-power steering.
Jamesy - Yep I always use AE oil, as for toe I run 3 degrees inboard and 0 degrees on the hubs. If you are running the kit 0.5 degree hubs just leave the inboard on 3 degrees and it'll be a little safer on power
