![]() Always scale the chassis with the driver sitting in it and in the spot of the garage each time. But if you want to scale the car this is what I recommend. It does not tell us anything about what the car is going to do once we turn the car, accelerate forward, or brake, this is when all the weight transfers and factors like center of gravity height, roll centers, tire offsets, shock dampening forces, and spring rates come into play. It tells us how fast the car is when it is sitting still, like in the garage. Remember that scaling only tells us a small part of the story. Q: What would be a good weight distribution to start with on a micro sprint? Front to rear and left to right.Ī: I can't just give numbers without telling my whole story. On a torsion front car you would add about 1/3 turn. ![]() On a coil car one turn =1/8" in height so this can be compensated by adding 1-1/2 turns to the side of the front with the smaller tire. 159" (not quite 3/16") difference in ride height. As you can see even an inch of front stagger will only result in a. Since stagger is circumference to find the diameter we must divide it by pi, which is 3.14, then we must divide the diameter by 2 to find the radius. I will show you how to calculate the change in ride height. Thanks.Ī: Because front tires rotate independently, unlike the rear tires, the difference in circumference (stagger) will only change the ride height, it will not make the car turn. If this is true, does it matter if both front tires are the same size? If the right front is bigger, is this more like adding cross weight? Please explain what the left front does. Read the results of our research and testing as we discover new methods that will improve your racing effort and help you become successful.Q: Mike, you mentioned earlier that front stagger does not help you turn. Horsepower cannot equal these gains.Join us as we explore the many existing ways to make your car faster through the turns. Gains in mid-turn handling performance over many laps represent the biggest gains in performance you will experience. ![]() When we achieve this goal, the car will be neutral in handling, all four tires will be working for maximum traction, and the setup will stay consistent over a longer period of time.The fastest cars do not necessarily have setups that will be fast beyond 20 laps. Balance in a setup is not just a neutral handling car, but also one where we know that both suspension systems, front and rear, are working together. Dirt and asphalt racers will benefit from this new trend in racing technology. That will be a major technical theme of Circle Track magazine articles in coming issues. All of the trial and error methods that have been developed over the past 30 years were aimed at achieving a balanced setup.During the past 10 years, racing technology has advanced to the point where we now know how to get to the balanced setup in an easier and quicker way. This term denotes a condition that racers have always sought. In this and future articles in Circle Track, we will be referring to a "balanced" chassis setup. ![]()
