The vanilla/space age belts uses larger gaps between the belt arrows, to more easily tell which direction the belt is moving, since at high speeds the arrows become very blurry. I suggest also increasing the gaps on your belts to help visualize this.

That is no small task.
1. The belts are all shared between the tiers and are color tinted to the tier. This saves on memory required I believe.
2. I don't have the original 3d assets or the art/texture skills to completely revamp all the belt sprites and animations. Doing this would require weeks of work.

The arrows being blurry is directly representative at how fast these belts are going. There would be no way around this, even if you made the spacing higher, the arrows would still have to move to the belts speed, making them very fast.

I see, well could you atleast clone it from the turbo belt as it has wider gaps? If possible ofcourse.
