Our mission at the RaceWise Dirt Track Chassis School is simple: help racers of late model, modified, and street stock-type dirt racecars improve their racing program. We provide help through education. At the RaceWise Dirt Track Chassis School, students learn how suspensions actually work and how tires make side and forward bite. This foundation of knowledge enables students to learn not only WHAT to do to improve handling and tire performance, but, more importantly, they come to understand WHY! The knowledge we provide takes the mysteries out of chassis set-up and tuning and eliminates guesswork and misunderstandings that are so common for most racers. All critical aspects of chassis set-ups, tuning and tires are covered in an easy-to-learn, step-by-step, organized, racer-friendly manner.
Rear steer. In the most basic terms, rear steer is caused simply by movement of the rear suspension. When the rearend articulates, moving one wheel ahead of the other, the movement is translated through control arms to the chassis. If both of the wheels move fore or aft the same amount, the effect is not noticed and referred to as zero rear steer. Obviously, this has a limited effect on helping a car corner at race speeds on a dirt track. It is when one wheel moves fore or aft more than the other that cornering becomes easier or more difficult.
Dirt car setup is undergoing a change, and has been for about five years now. What used to be standard setups are a thing of the past for the top teams competing in dirt late models, modified, and even the stock classes. It may be an affront to most dirt racers to say that technological changes that have taken place in asphalt racing have trickled into the realms of dirt racing. The general trend in all of circle track racing has been to make changes to our setups and car construction to make better use of the four tires, especially the left front tire. The primary indicator of a left front not working is when we see that tire off the ground through the middle of the turns. A tire not in contact with the racing surface does no work. It is dead weight.

This unique camera angle shows exactly what is happening in the rear end of a 3 link. This was filmed in June of at Kennedale Speedway Park. Is footage like this helpful to your setup? Comment below. I would like to see right front that would show how front works thru the corners. I still run a 3 link on my A mod hear in East Texas. I have been out of it for a lil while now … Just started back here a month ago.
Rear Steer: The Key To A Quick Lap In Dry Slick Conditions
Mod 4 3 link
Rear steer in a circle track race car is a condition caused by suspension movement. Under the right conditions, rear steer can be beneficial and enhance performance. Under the wrong conditions, it can ruin your handling. We do not necessarily need to know the exact amounts of rear steer our cars are subjected to, but we do need to have a solid understanding of what produces rear steer and what effect rear steer has on the handling in our cars. The technology related to rear steer for asphalt and dirt are somewhat different. There are a few similarities, but many differences in how we evaluate and use rear steer for each group.
I here alot of people saying the same thing about a 3-link. They can't beat a 4 bar off the corner. I have already called and talked to DW about switching mine over to a 4 bar z-link and it will cost around to Does anybody know where I can get it down cheaper? I going to run a couple of more races then put it up for the summer if anybody fines something that works please post.
