I think the thinking is weight transfer/balance in turns?

The track guys, IIRC, say that you need more front bar for better traction/oversteer though.

All I know is that it's a balancing act and too much/too little of either bar plays different roles depending on what kind of driving you're going to be doing.

My input, for me, 99.9% of my driving is very aggressive street driving, so I got the Nismo S-Tune bars, because I assume they know what they're doing a bit, and they are making a stiffness setting for the masses, which I fall into.

I tried looking online, and you're right I'm getting a lot of conflicting information. The bottom line was "it depends" and its all about balance. Increased stiffness may increase grip, but then again going too far reduces it. The best I understand it now is thus: (if someone understands it better please correct me if I'm wrong)

The front is looser than the rear under that scenario. Which means the front rolls a bit more, and since the rear doesn't roll it has to slide. So it's all about the balance of the two.

I'd still think that softening the front relative to the rear would be the way to increase overall traction. I.e. upgrade both front and rear, but put rear on stiffer and the front on softer. So both bars are stiffer than stock, but the rear increases stiffness more than the front.

Suspension is confusing...
