To use thicker swaybars or not?

[MTA_NRT]

Hello,

The question is very simple - is it reasonable to use thicker swaybars with keeping the same as before balance between F & R ones?

I.e. if front is 15 & rear is 17 mm in diameter, and if such setup is satisfying in terms of steering character, is it a reason just to make it thicker with keeping the same ratio between F & R?

I.e. let's formulate the question in other way:
We have hypotetic car X which has rather good steering character, and has the F-swaybar with dia of Y & R-swaybar with dia of Z, what will change if to make the proportional increase in dia of both swaybars, let's say Y+20% & Z+20%?
How the behaviour of the car will change? What will be the difference except evident mass growth because of thicker swaybars which weighs more ???

The prob is that we wonder, does rally stresses & speeds & roll levels obey us to use thicker swaybars or it doesn't change anything except mass?...

Thanks!

Hi there,

Your question is a good one but we have to understand that we are dealing with a variety of chassis's, roads and of course driving styles. Generally speaking a car maker will produce a car to be be more understeer biased for obvous reasons and so it is our Job to adjust this . In most instances uprating both front and rear Swaybars an even % is a 'responsible' choice but this is normally only good at a limit of 20-25% increase and for spirited on road driving only. At the end of the day we take into account numerous factors and spend countless hours in the track before a decision is made and even then we may list 2-3 bars combined with 3 point adjustability.
