I know everyone says no bar rear and stiff bar front to prevent understeer. And some people try to explain that in a number of threads but I'll admit to still not getting it.





Found this to be a really good videos. Of course like every other video or article i read on the subject it contradicts the collective knowledge of all the actual track drivers in this forum. Just seems like the basics laid out don't apply to the 370z for some reason.

The only thing I can think of is that the inherent roll stiffness of the 370z is heavily rear biased. Causing excessive understeer. so much imbalance that even adding a heavy front bar and removing the rear bar won't flip the balance the other direction. It will just get you closer to 50/50 roll stiffness front and rear. /shrug.

True that it seems like the 370z platform contradicts everything online that stiffer bar reduces grip. It’s a fact that the overall grip of a car will be higher when the tires are more evenly loaded, which is the exact opposite of what a sway bar does (removes load from inside tire and applied it to the outside tire). So it’s especially confusing that having a stiffer front bar, which distributes the load more, actually increases front grip.

My understanding is that the z has a lot of roll in the front from the factory, which can make it more difficult to control the tires with respect to the ground, considering camber gain during roll. With a stiffer front bar, the tire is more controllable which makes setting up the car easier for achieving higher grip in most cases. BUT… I’m no expect, just trying to make sense of everything I can find online. I certainly don’t have enough track experience yet to justify how a sway bar change actually affects grip levels.
