Wheel loads - please read and explain

[CSB]

I got this out of Race Car Vehicle Dynamics, can anyone put this in laymans terms?

If a left turning car is loose, increasing static weight on the on the RF will result in a greater load difference at the front axle while cornering and thus a decreased maximum side force potential for the front track. At the same time, the LR load is increased which results in a decrease in load difference at the rear axle and a corresponding increase in maximum side for capability for the rear track. Both of these changes are in the direction of push and the car becomes tighter while cornering.

I'm not sure I follow that 100% as it doesn't say whether you are in deceleration, coast, or acceleration which is going to make a difference.

If you increase the static weight on the RF, that can be just adding wedge or bite which increases the RF and LR static wheel weights. We all know that generally loosens the car in and tightens off. So if they are talking exit or non deceleration then yes.

I would also venture to say that is probably relating to asphalt, but that’s a guess. An asphalt car uses the LF a lot more then a dirt LM would. They also have higher speeds and rely on aero much more then a dirt care can due to track bumps and ruts.

Thanks. Pretty sure it pertains to asphalt. Its really tough to study the how's and why's of a DLM, pretty much every technical book its asphalt based.

This is definitely asphalt speak. I'd say they are talking about a steady state situation in the corner where you are not really on either pedal too hard.

Basically they are just saying that 2 evenly loaded tires (both fronts or both rears) will have more grip than one heavily loaded and one lightly loaded one. This is not always the case on dirt. It depends on tires, surface, many other things. If they were the same, you would want all your ballast as low as you could get it.

That book does have some good info in it, but this isn't it.
M'bilt & Billet's right on.

I believe the statement is referring to cornering only. The static adjustment of wedge applies to dirt as well as asphalt with the exception of a very inconsistent track.
