I'm really glad you wrote. I get involved with specific setup parameters and have forgotten to present the basics that are needed by a team to fine tune its chassis. I will schedule an article in the next issue that only deals with suspension changes, what they do and how much influence they have and in what areas. There is a ton of similar information out there and every car builder usually has a setup sheet that tells how to correct "loose off" or many other conditions.

What I can do is not only tell what to do in a specific order of magnitude and logic, but tell the effects each change has on other factors. We preach developing a dynamic balance to the setups and not just a handling balance that makes the car neutral. I always say, I can make a VW neutral, but I want to make my race car balanced.

Metric Mod Racer
Bob, My father and I have been avid readers of Circle Track for the last 15-20 years. I enjoy the many articles and they have helped with my racing over the years. I run a Limited Modified or IMCA Sport Mod as they are called up north. We utilize the metric chassis and all of the stock suspension points.

I'm still lacking some forward bite and would like to utilize the free calculator for locating the height of the four-link roll center. We have come a long ways with the metric chassis finding speed and something new to help the car to pivot or roll the center of the corners better each week would help.

I appreciate your articles and hope Circle Track will continue to provide us weekend warriors more valuable information. I'll never make it to NASCAR or have engineers fine tuning my car each week, but the satisfaction I find trying to outsmart my competition has added a new twist to racing. Racing has become very technical and Circle Track continues to lead the way providing cutting edge technology. Thanks for all you guys do! Mike Kressley Limited Modified 9K Houston, TX

Mike, I wrote a while back that we racers are, in reality, scientists and design engineers. We fit the descriptions to a "T" and we don't necessarily need degrees to prove that. Many successful professionals in all walks of life can become very well educated outside of the education system. I'm not necessarily against formal education, I just realize that, and am example of, someone who can achieve a high level of knowledge about a particular subject on his own. Smokey Yunick was, in fact, a self-taught thermodymamics expert as well as a mechanical engineer and proceeded to educate many degreed members of the racing community.

Because we as racers enjoy this sport so much, we have a high capacity for learning. Anytime you are interested in a subject, learning comes easy. In school I was always good at the subjects I liked and did poorly in the ones I didn't. We are all like that. So, learn all you can and be aware, you and I will never know it all.
