sway anti roll bar front and rear 155Q4

**Stichl** · 28-03-12, 08:46

Hello,
can someone tell me about the experiences, done with the thicker swaybars?!
I intend to install stronger ones in my car. Before I do so I would like to know if this invest (to order the 28mm /24mm version from Australia) is worth it?!
My car is no race car, but "sportive weekend streetcar", only.
I found a front arb from an Dedra Integrale, which I could install.
Additionally I thought to order the 24mm rear arb from Australia, to combine it with the 24mm Dedra front arb.
Is this a good combination or could it become too stiff in the rear??
Or ist it sufficient to change to the Dedra front arb, only (for a sportive street car, no race)?!
Thank you very much for any comments.

I'm not sure if the coupe is the same but the 155 body is not as stiff as it could be. I'm sure we have all been shocked when we have jacked the car up only to find that the front doors don't open or shut very well.

I found that the Dedra front anti roll bar along with a front strut brace tightened up front end response no end. There is still some understeer but turn in to corners is now much more direct.

It might be worth trying this first, then seeing if you want to adjust the handling any more.

What suspension are you running at the moment?

Might be worth posting these again:

Hello Steve,

Thank you for your answer. I will do as you stated and try the Dedra swaybar first - I have a front strut brace installed as well, additionally I did seam welding to the front axle carrier. I hope this is sufficient to get it stiff.
A good solution in my eyes is to use these braces from an 156 GTA

To your question: I have D2- coilovers installed - these are the coilovers for the Fiat Coupe 20VT, not the Alfa 155 Q4. I had to do minor changes to the rear axle carrier to get them fit. Problem is that I have the wider wishbones from the Fiat Coupe 20VT installed (front) - therefore I would have needed the front suspension from a Fiat coupe in combination with the rear suspension from a Alfa 155 Q4. But I think that there are almost no changes... only the price for the Alfa 155 Q4 D2-coilovers is much higher than for Fiat Coupe (I have read a few minutes before)???

Do those braces bolt between the front subframe and the main body? Sounds like a good idea. When you jack a 155 up you can actually watch the front door move in its surround so any extra strengthening would be welcomed.

I was just checking you didn't have the standard saggy suspension.
