1,5" vs 6" travel distance for sim racing motion systems

When considering a motion simulation system for sim racing, one of the first questions that comes to mind is, “What should I get?” While this is a valid question, a more precise one would be, “What do I need?”

We've already explored the different DOFs (dimensions of freedom) and their benefits, and travel distance is an important factor in this context. The available space in your room can be a significant consideration when choosing between systems. The larger the travel distance, the bigger the motion system, meaning it will occupy more space in your racing setup. For example, a 6DOF motion system with a 6” travel distance will be much larger compared to a 2DOF system with only 1.5” of travel.

The key benefit of a 1.5” travel system is its quicker responsiveness. It reacts faster, providing a snappier, more immediate sensation that some racers prefer. On the other hand, the 6” travel system offers smoother and more nuanced immersion, allowing for a deeper and more detailed experience. However, while the 6” travel provides greater realism, it can lead to motion sickness for beginners, as it is a more intense experience. These systems also tend to be more expensive due to the larger and more complex components required for their functionality.

Ultimately, the more travel distance you have, the more detailed your motion experience will be. A longer travel range means greater accuracy in simulating real-world motion, enhancing your sense of realism and even impacting your overall performance. But keep in mind, this comes at the cost of space and a higher price tag.

Choosing the right motion system is about finding a balance that works for your preferences, available space, and budget. The ideal choice depends on how much immersion you’re looking for and whether you prioritize a more compact system or the most realistic experience.

So, have you decided which motion system is right for you yet?
