STH Multi-Step Build Plan/Thread

i didn't delete that post fast enough i was remembering wrong.

Adding stiffer front bar would increase the load on the outside tire. which if the car had 50/50 roll stiffness would decrease the front grip.

And adding load to the outside tire, and removing it from the inside tire, causes lower overall grip. That’s just physics related to tire load sensitivity and the fact that the coefficient of friction decreases with higher tire load.

So it’s something else going on that makes the Z have less under steer with a stiffer front bar.

yeah exactly my confusion. Also would be interesting to know how many people with stock suspension or stock balance spring rates have done the roll bar thing. Or if they experienced the decrease in understeer with wildly different than stock balanced spring rates front/rear.

I don't think i'm going to really find an answer i guess. Like it would be easier to just buy suspension and tires and then test different sway bar setups to see what is most balanced.
But honestly I want to know why more than I care about the resulting handling.

Same here! The engineer side of my brain tells me I have to justify WHY it could possibly make sense even though it has been confirmed by all the track guys on here.
