After a spring plate failure I'm having to replace the spring plates. While I was there I was going to replace the torsion bars since they're all the same old age. Currently they are 24 11/16". Is there an advantage to running either the 24 11/16" bars or the 26 9/16" bars? This is on a 2-seater of unknown weight (guessing 1800-1900 lbs). I think they're 30mm based on the stamp "31130". Also, I was going to buy the SAW Chromoly race plates, is that what everyone runs? Thanks in advance.

1800-1900 seems very heavy for a 9 car unless you are accounting for spares, fuel, and people being in it.

I think most 2 seaters are running 25 or 26 mm intermediate bars. 30 mm is a really big bar that probably barely moves unless your car is grossly overbuilt.

The sway away spring plates are fine as long as you go chromoly.

I'm only guessing at the weight knowing what my 1600 single seater weighed back in the day. Even if the car weighs 1500 with me and my son in the car we're well over 1900. I know, we need to lose weight in the cockpit.
The census has been the 24 11/16" bars are ok length so I will get spring plates, weigh the car and maybe order smaller bars.
