I am working on the new Chassis Guide as I have promised. Everyone needs to contibute to this to make it the best it can be. I will be posting scenarios in different classes and need YOUR opinion of what the car needs to help these specific situations. Please contribute to make this guide the best we can make it.

Here is the first scenario for Lates!

4 bar late model, have no bite on a dry slick track, what can I do to the bar geometry on the car to make it better out of the turns?

Please contribute guys!

Raise the left side bars up on the chassis. Stiffen the spring on the right front. Raising the left side bars drives the tire under the car to get a bite. Stiffening the spring on the right front will get the weight to transfer to the left rear quicker.

The question is referring to the bar geometry, yes raising the bars (upper and lower if extremely needed)(both sides) will add bite. But springs do not have any effect on weight transfer from corner to corner. A stiffer RF will only make you looser going in, which in-turn on a dry slick track makes you loose off.

Jammin,More angle on the bars. Move the arm mounting points on the birdcage forward of the axle centerline. Softer RF. Stiffen torque arm.

Of course all these things depend on every thing else ............could go the other way........I wish you the best of luck with this project............
