Hi all, I have 3 questions: Q1: Distance between front rollers and rear roller: I am thinking the further apart the front and rear rollers, the shorter the distance the car travel around a corner, hence the faster the car turns the corner. But this will make the corner a sharper turn and stability can be an issue. Is my understanding correct? Q2: Height of the front and rear roller: I know the lower the rollers, the lower the point of gravity, and hence the more stable the car. However, does this theory only applies to the bottom rollers or both the bottom and top rollers? In other words, should the top rollers also be placed as low as possible? Q3: Width of the car: I define width as the distance between the left and right fronts roller as well as distance between the rear left and right rollers. The wider the car, the more stable and its always a golden rule to max out the distance between the front/rear left and right rollers. Is my understanding correct? Thanks All.
