It's an acceleration ability that allows you to shoot far ahead of everyone else. The reason this ability is good you have to go more into the weeds of the specific track layout.
I don't have the picture on hand, but basically, this skill activates early on in the final corner before the final straightaway. This is the most important part of the race. When it kicks off, it allows your end closer to surge forward ahead of everyone and then hold the lead in the final straight. A golshi with it equipped will get 10 lengths ahead of a golshi without it, which is what makes it so incredibly strong on this course. The descriptions don't really do a good job of explaining the mechanics behind it. But what you need to understand is there's no other acceleration ability on this track that gives you the same advantage.
In the previous CM on the medium course, it was Taiki Shuttle's Shooting to Victory and Maruzensky's Red Shift which were the good acceleration abilities, but on this map they're practically useless because they activate too *late*, so not even worth grabbing. Every course is going to have abilities like this where they're strong on some and weak on others. It's all about where it kicks in on the final corner.
