Help indexing torsion bar. Quick question..
Hey guys, I'm raising my car up by one inch. Already put in the weltmeister spacers up front, that was easy, but anyone know how many clicks will raise the rear by a rough 1 inch? I know final adjustment will be by the spring plate. Im pretty sure I have a 28mm white Automotioin torsion bars circa 1998. Also, I think I want to go clockwise on the spring plate collar-driver side, and counter-clock wise on the passenger side. right??
thanx a bunch

The inner splines adjust height by 66mm per spline. The outer by 60mm/spline. To get 1" (25mm) you will need to move 4spline on the inner and 4 the opposite direction on the outer. 264mm - 240mm - 24mm.

Man, it's been a PIA to get this thing down. Got everything off, just need to "pry" the tube down. Just thinking, maybe I'll just change over to adjustable coil over springs on the rear and call it a day. Stupid question: If I do go the coil over route I need to completely remove the torque tubes right??

torsion bars, not torque tube. you can also get rear coilovers with correct spring rates (helper springs) in conjunction with your stock or performance torsion bars to help with fine tuning (corner balance and some ride height). Torque tube is not relevant on this subject... the torque tube connects the transaxle to the the clutch .

If you go to coil overs you will still need to reindex your torsion tubes. Persevere at getting the torsion tube out. If the control ars are still attached to the the tube. Jack them up so the tube is not trying to rotate that is normally what jams it. Once you take the wight of the control arms (and hubs etc) off the t tube is should drop down without too much difficulty. Then you can start reindexing 
. Reindexing torsion bars is a good 944 right of passage. Don't let it beat you

Ok, Thanks. So, on the drivers side I will need to rotate inner splines by 4 clicks CLOCKWISE, then reindex the outer splines by 4 clicks COUNTERCLOCK-WISE to get 24mm of height (raise the car) Correct? Again, goal is to raise car by one inch or so...
Opposite rotations on the Passenger side, Correct?

Before you go to the trouble of reindexing those bars, you might want to check the position of your eccentrics back there. If they are at their lowest setting you can get an increase of 3/4in right there, that might satisfy your “one inch or so” rear height adjustment without touching the torsion bars.

Thanks MAGK944, been there-done that. No dice.
Well, the Beast is down. Before I go into and expose the TB's gonna do a lot more reading and take measurements so I don't get lost.

Ok, I can see this is gonna be actually pretty easy (with you guys help!). One thing....... Just realized after measuring that the torsion bars are actually 30mm, NOT 28mm. Does anything change? On my 30mm do I still go 4 clicks clockwise on the inner, then 4 clicks counterclockwise on the outer (driver side)??
My bars are: "Genuine Sway Away Product" 30mm OD, 19mm ID. At the ends they are stamped "L" "1228" "1097"
Thanx!

Whew!! Gotterdone! I was initially worried because there was only a little better than 1/2 inch drop (elevation of body) from the end of the spring plate to the banana plate above, but then remembered that further down this will translate to a larger arc as the angle opens up, so I think I'm good. I'll have my son help me button her up in a few days, while im in there will re do CV boots/grease etc., need to get these by UPS
Will report later. Thank you all involved :-)
