What Does Rear Toe in Do RC Car?

Rear toe-in is one of the most important setup parameters for RC cars. It can have a huge effect on how your car handles, and it’s worth taking the time to get it right. So what exactly does rear toe-in do?

To understand rear toe-in, first you need to know a bit about steering geometry. The angle of the wheels relative to each other and the chassis is referred to as ‘toe’. Toe-in is when the front of the wheels point slightly inwards towards each other, while toe-out is when they point outwards away from each other.

So why would we want our RC car’s wheels to be slightly toed in? Well, it’s all about cornering stability.

When you turn your car, the outside tire needs to roll further than the inside tire in order for it to stay on its intended path. If you have no toe-in, then this difference in distance travelled will cause the wheels to push against each other and resist turning. This makes your car feel sluggish and unresponsive in corners.

By adding some rear toe-in, you can counteract this effect by creating an imbalance between the left and right tires that helps them turn more easily. This allows your car to corner better without sacrificing straight line stability or speed. The amount of toe needed will depend on a number of factors including track conditions, driving style and vehicle weight distribution, so it’s best to experiment with different settings until you find one that works best for you.

Conclusion: Rear toe-in is a crucial element of RC car setup that can have a huge impact on handling performance. By creating an imbalance between left and right tires, it helps them turn more easily without sacrificing straight line stability or speed. The exact amount of toe needed will depend on many factors, so it’s important to experiment with different settings until you find one that works for you.
