![]() Wow, I'm confused and I know what I'm doing.ġ. The tie-rods need to be level and so does the pitman arms. I have seen many bad designs over the years. So does the angle of tie-rods in the front-end. Setting toe, it should always be set on the LF and not the RF due to the load on the RF. Front stagger along with caster will determine when this occurs. If you put too much front stagger in the kart it will push coming off. Think about this, front stagger, many say it makes no difference since the front tires have no positive connection like the rears. There are far too many variables to give a generic setup. This is why you "must" do your own thing. The reality is, the entire setup should be different. The setup may be the same but the approach is very different. To throw another monkey wrench into the equation, suppose a driver has his CG biased toward the LR but is very tall and has a very high VCG? Then there are the guys who carry their weight in different places, one has a lot of upper body weight and the other has lower body weight. Again, depending on the location of the CG. More stagger is used to loosen the kart, so more cross-weight is used to tighten it up, ie more drive off the LR and less grip on the RF depending on the CG location. On LTO karts, cross-weight is usually used in conjunction with rear stagger (where the right rear tire is larger in circumference than the left rear tire) to balance handling. Again, you must consider the location of the CG. The difference is the grip level that the RS and LS tires is running in is almost the same depending on how the track "rubbers up". ![]() On asphalt, the situation is different, but the same. If the CG location adds more weight to the RF, then it may make the kart loose. If the CG location adds more weight and grip to the LR, then it makes the LR more dominant and makes the kart want to push. a 2 where the RS tires run, then depending on the CG location will determine what you do with cross. On a scale of 1 to 10, 1 being drier and 10 being moister, say a track has a 6 where the LS tires run vs. Hence part of the confusion.Īnother part of the confusion would be how the track drains water and holds water. Therefore, adding cross or decreasing cross can and will have very different results. The result will be totally different in handling. If the CG is biased more to the left and toward the LR, then adding cross will add more weight to the LR. If the CG is biased closer to the jacking axis then adding cross will add more weight to the RF than the LR. Here is the issue, the relative position of the CG compared to the jacking axis, a line drawn from the center of the LF/RR tire contact patches. Cross-weight is also called wedge: If the percentage is over 50 percent, the kart has wedge if it below 50 percent, the kart has reverse wedge. To calculate the cross-weight percentage, add the RF weight to the LR weight and divide the sum by the total weight of the kart. For those of you who are beginners cross-weight is the percentage of diagonal weight of the RF + LR weight total compared to the total weight.
