I made the decision based theory, opinion, sale and moonphase.
The more HP/Tq in a 911 the more it can squat under throttle. Most of the 3.2L cars are 29 or 30mm in Rear (for track). My car has 265hp (at crank), so i opt'd for elephant racing's recommendation 31mm as a track option. I also have AirConditioning and heat, so car has more weight than a stripped track car (2780lbs w/o driver).
If you have a turbo, you might opt for the 33mm on the track.
Also note some of the 993s in our club are using 600LB or more springs. The car barely moves when you press down on the rear bumper. (like the Haas mobile)
When all is said and done, the 23/31 torsion bar combo is streetable on 17" street tires, without extra visits to the dentist.
Note my rear sway bar settings are soft with the 31s. ymmv.
However , 30mm v 31mm you are splitting hairs....pick one.
