Torsion bars
I am going to upgrade the torsion bars on my 911, 3.2. I have planed to install 23 mm Sander tubular bars in the front and 29 mm Porsche compact bars in the aft.
I am wondering about this combination and what thickness will there be on a solid bar that have the same stiffness as the 23 mm Sander tubular?

In general, 23mm is a bit stiff for a 3.2 911, unless you plan on some type of competition. I am running 22mm on my 89 turbo, which is quite a bit heavier car. 22/29mm is a popular combination for a street driven 911. A 23mm solid bar will be "thinner" than a 23mm hollow/tubular.
