Default Determining Torsion Bar Size...

Does anyone know of any way to determine the size of the torsion bar without dissassembly?

I'm asking because even though the PO believed the bar had been changed to a 30mm (the rear end has been lowered/indexed) the suspension just doesn't feel all that stiff. I know "bouncing" the rear end is far from scientific, but is there a propceedure (like: compress the suspension and inch with the tire on a scale and compare before and after readings) that might save me the dreaded torsion bar removal torture?

I believe you can jack the car up and take the ends off.
Then just slide the t-bars out a bit and measure them.

TonyG was telling me about how if you cut a hole in the side of your car, you
can slide the t-bars out without the huge hassle.
So I assume you can do the same without the hole if you just plan to measure.

Get a string and measure the circumference. Then divide by Pi.

I used the speadsheet on the AZ PCA site to calculate the uncompressed position of the bars when I switched to the 29mm bars. It worked very well. You should be able to back into the bar diameter using the spreadsheet.

Good Luck
