Hello,
may I introduce myself. My name is Juergen, I am owner of a Fiat Coupe 20VT with a lot of modifications, thus a conversion to a 4x4 drive from a crashed Alfa 155 Q4.
Up to now I have measured 565HP out of the Fiat Coupe 20VT engine. My first engine got a damage to crank bearings, because of a bad constructed oil sump. I needed a self-construction to get the transfer box mounted. But I forgot to install enough baffle plates. Thus in corners the engine did not get enough oil.
Now I changed whole engine and bought a new turbo (GTX35R) - my goal is about 650HP with E85.
To strenghten the Alfa 155 Q4 gearbox I mounted 3 strenghtening plates, additionally I changed to strengthened gears 1-3.
Up to now the 565HP were no problem at all.
To get a stiffer chassis, I additionally modified the front subframe (seamwelded), I installed an additional underfloor strut, changed the rear subframe bushes to solid ones and now I am gonna to install 156 GTA front braces between front subframe and chassis.
Additional changes: D2 coilovers, big brakes (356mm front, 305mm rear), etc.
Only part I never found was an upgrade for the anti roll bars.
Now I read that the front Dedra Integrale anti roll bars are better / stronger than the 155 Q4 ones?! This sounds strange to me (and is annoying - a few years ago there were a lot of them in German Ebay, meanwhile they are very rare).
Additionally I heard that there is a possibility to get upgrades parts from Australia?!
Now my question: Is this upgrade (28mm front, 24mm rear - really much!) a good solution for a street car like mine?! I would like a stiffer suspension with adequate behaviour for normal roads. I don't do races.
Therefore my preferred solution would be the 24mm front anti roll bar from Dedra in combination with the stronger 24mm rear anti roll bar from Australia?!
What is your opinion to this?!

Thank you very much

Juergen
