Update: So I made this post last night and scheduled it. Later I looked it up anyway and I kind of get. At least as far as I think someone without an engineering degree can.

So now it’s a pop quiz to see who can get it right!

So if you have two cars that can pull the same amount of maximum lateral g’s, but weight differently. The lighter one will be able to corner faster, because the heavier one will reach the same amount of lateral g’s sooner because it has more weight.

Edit: This is wrong. Both cars will be going the same speed.

But if for example you’re trail braking. You’re transferring weight from the rear to the front. This causes the back end to have less grip than if there was no weight transfer.


But from the first example. Shouldn’t the back end have more grip since there’s less weight on it? And shouldn’t the extra weight on the front cause understeer? Obviously understeer will happen if you do it too hard, because you’ll overload the front, either with too much weight or too much braking and cornering.
