We have had karts in the past where there were different pills. The pills were numbered I, II, III, and IV, I believe. One had the numbers clockwise and the other pill was counterclockwise. To get the same caster and camber on each side, one of each was used. If you used the same pill on both sides, you could either have the same caster or the same camber, but not both. This was in the vicinity of 2006 on a shockwave cadet kart.
