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.
