View Full Version : Stiffening Rear

Is there anything that could be done to a stock torsion bar to make it stiffer?
Seriously. What does anybody, what can you, do with a stock torsion bar after you replace it?
I've seen formulas for Torsional Constants, J, but I don't know how these translate to performance. A 25mm bar doesn't seem to be considerably stiffer than a 25mm, but a 28mm bar is ( from the radius exponentially ).
Can I alter the rear torsion bar, and if not, what could be done with it?

I moved this into the Abarth section and tweaked the title to get more interest.
