Hi i have a type-r with whitline suspension 3way and whitline goodys on the car front and back now i really want to put on some 27mm swaybars on the car.
its a 440hp 6speed with dccd but on track as you now its gives a little understeer.
Now i was thinking of using a 27mm at the front and 24mm on the back to counter this or is it beter to just put in a 27mm on the back to.
And deal with the understeer my self or just by setting the dccd on a other setting as i sometme do.

I’m about to test this weekend 27mm front and back on my hawkeye, I was advised by the whiteline guys the wider the tyre the thicker bar you want, I’m running 285 wide and took a chance with the 27mm all round. From what Iv read previously though you want your bars the other way round to help with your understeer so the 24mm up front and the 27mm rear.

Then you will get more oversteer i belive.
But maybey some one else can clear this.
And did you have under or oversteer before the swaybars.
and lett me now what the findings are.

Bigger bar on the rear will make it more tail happy.

That is why if you not going bigger all round, most people get away with only changing the rear to reduce the under-steer.

Or, bigger bar on the front, with sticky tyres, will stop the camber curve collapsing, to a degree, and stop the tyre rolling onto its wall = reduced understeer. Might be useful on a tight/twisty circuit/autox.
It will still understeer but at much higher speeds - speeds you may not reach. Understeer at the very limit is useful, if you want to drive home.
But, the benefit of awd is traction, so impeding traction, by reducing suspension independence, via big bars, is unhelpful.

The car drives good but just want to improve the swaybars and look what it will do with bigger ones.
It just have a litle understeer at the very limit and maybey what you say get more corner speed with bigger bars.
And maybey reduse bodyrool.
But would you do bigger al around or 27mm front and 24mm rear.

i hope its a track car -27mm bars have no give at all -lots and lots of crashing over manhole covers,may even reduce grip being so stiff

My thoughts exactly, especially as its on a classic too.

24mm adjustable rear and 22mm front is great on my classic saloon.
