G37 Track Set Up. Oversteer Help.

2.2Lude

Thanks for bringing that up. This is something that was always a bit hard for me to understand when I was originally doing research last year on how to get a base set up in place for my car. Admittedly, I kinda just went with it thinking it'll work out without fully understanding it.
I read a lot on this site from members like yourself and others that have provided input.

Maybe you can help me wrap my head around the concept better.
Traditionally a stiffer front bar will INCREASE understeer by REDUCING GRIP correct?

So how does a stiffer front bar both INCREASE understeer and INCREASE/ADD grip?

Or is it just something that comes into play with a square tire set up to improve the front grip with wider tires but use a stiffer bar to increase understeer and balance the cars front/rear traction?
