I just rebuild my control arms and everything and I’m starting to assemble it all and was wondering how to clock the T-bars they are 1.03 bars from pst I want the car sitting at a low stance and anything else I should look out for while installing everything? Thanks Jdpdart
Pst 1.03 t bar clocking?

Any ride height adjustment is in the adjuster. I don't believe there is any preloading.

F/R does not matter so long as they are on correct side. Bear in mind L is driver's side. They are only going to fit and work at all at "one" clock. Otherwise the car will be either on the ground, or jacked to the sky. Not sure if you can even put them in on the wrong hex flat
I don’t know specifically about the 1.03” PST bars, but some torsion bars can be installed on the wrong hex flat. I know because I’ve done it! Pretty sure it can only happen with bars that have little or no indexing though.
Basically, letting the LCA hang all the way down like the factory described in the LCA install goes to a different flat. With stock LCA’s it’s harder to do, they hit the K frame before they hang down far enough if they’re all the way onto the pivot pin. But, if you have the QA1 tubular LCA’s, or let the stock LCA’s slide backward on a poly LCA bushing, you can clear the K and the LCA will hang down further than the factory intended.
The end result is a car that sits ridiculously high in the front and can’t be lowered.
With the PST bars you can probably only install the LCA’s one way. If you want the car lower, and install larger bars, I generally ignore the FSM about where the LCA should be on install. Larger torsion bars often have different indexing so the FSM description of the LCA position isn’t accurate, and trying to force the LCA further down can put you on the wrong flat. Instead of letting the LCA hang all the way down, hold it close to where you want it at ride height. For a lowered car this will be close to parallel to the ground. Then take a look at the torsion bar hex. More than likely you’ll lower the LCA a smidge and it will line up.
What you don’t want to do is slide the LCA back any clear the K to force it lower. Or, if you have QA1 LCA’s, don’t let them hang all the way down as they’ll literally hang straight down. Starting close to your expected ride height should keep you from ending up a flat off if you’re using aftermarket parts.
There’s no preload, but if you index the LCA a hex flat off the range the adjusters control probably won’t line up with a ride height you want.
