Default Large diameter swaybar and bias question.

This question is for those of you who have used the larger Whiteline XRD bars (the ones that go up to 26 or 28mm in the rear).

I currently use a ground control/Koni setup and i have adjustable whiteline bars in the front and rear. I have the 20-22 front bar and the 20-24 bar in the rear all with endlinks. I use the front bar set to 20 and the rear set to 24. I like the handling feel with thos setup as it give me nice turn in, good front and grip and the tail rotates seemingly well for a scooby. IT seems that the 4mm differential between the bars makes for this nice handling. If i raise the front bar mm setting, the front looses overall grip and the nice handling characteristics start to go away. Raise it all the way and it handles like crap. If i lower the rear, the same thing happens.

My question is this... with the 4mm differential, i get the better handling characteristics. Hypothetically, would this be the same if i had a 24mm front bar and a 28mm rear bar (provided they were available)? Or would having that large a bar in the front (even with the rear size bias) be too stiff for the front and take away grip. Since adjustable swaybars can be more of a tuning aid than fixed rate ones, would i end up with the same sort of chandling characteristics with overall less body roll since i am using the same basic ratio, just heavier bars?

Your spring rates come into play also. There's more than just bars that play into how well a car rotates.

I'm aware of that. I thought that i had indicated that above. Sufficed it to say, with all else being equal, would what i asked hold true? Please don't bust my chops with speculation, i am looking to hear from folks who have used those heavier bars and thier findings regarding it.

Your sway bar can be too stiff. If it's too stiff, your spring/shock won't be as effective because the sway bars are doing work for your spring/shock. Although you are maintaing that 4mm differential, is your spring/shock stiff engough for the increased sway bar diameter? Bigger is not always better.

If you want that same differential run no front bar at all, and run the stock bar on the rear. See what you think.

Making our beautiful fully independent AWD suspensions fully dependant with swawbars equivalent to live axles is not the answer.

I'd say if you want less body roll, correct that with rebound damping and spring rates, not rollbars.
