I know this question comes up a lot, but is there any rule of thumb or hard data on matching the torsion bars to rear coils springs for best performance?
I have 140lbs springs in the back. I was thinking of getting 180lbs.
What size torsion bars are good to keep everything balanced with both?
The cars only purpose is for autocross use.

With 180# rears, use 21mm front torsion bars with a 19 mm stock or adjustabel front sway bar. NO rear bar with this set up....If you have a rear bar with this combination you will get too much oversteer.
do you have Koni's or Bils?
