Stagger plays multiple roles in both lateral and forward traction. The benefit of having the right rear slip is that its surface speed is faster than the left rear, so it is trying to help go faster instead of just dragging along slowing us down. ![]() Looking at the contact patches, it should be easy to see which it is. However, this shape gives more rolling resistance.Īs we know using a staggered rear axle to go straight, one tire has to slip. The left rear is generally more square or even longer than it is wide, generally considered better for forward traction and less desirable for lateral traction. This shape is thought to be better for applying lateral traction and not as good for forward traction, but induces less drag from rolling resistance. If you drew out the static patches on sheets of paper, you may have noticed the right rear is wider than it is long. A look at the contact patches can give some clues. As you know, we use different tire width combinations on our LTO chassis. I think a discussion of the static state is also warranted. Most emphasis is generally placed on the dynamic. ![]() If you followed the chassis math thread, I talked about tire contact patch shape in both the static and dynamic modes. I think it looks similar to the post above. I wrote this some time ago in a discussion about stagger. The whole premise is built on making maximum roll speed with limited horsepower. The right rear slipping is helped along by high cross, tire selection, thin cut rubber, tire prep, etc. Actually, the left rear is in control of the rear of the kart most of the time. Left continues to reload, right rear unloads, allowing At some point stagger is correct to let both tires pull equally out of corner. After apex, left rear reloads from cross. At the apex, right rear is more loaded than left rear, allowing left to slip slightly, (maybe). ![]() As entering corner, right rear loads, making stagger proper for turn in. As the least loaded tire on a solid axle, the right rear slips on straightaway. basically the same going down straightaway. Statically, right rear tire is least loaded. Probably been discussed before, but, here is how I see modern lto karts operating.
