911 Rod

The front end of my 86 911 is now complete.
Thank you for your input.
Now to tackle the rear.
Any little tips before I mark everything and remove the torsion bar caps?
Thanks in advance.

I assume you have read the various posts etc?
Mark the springplate angle on the body in pencil to give you a rough start.
Mark the toe & camber bolts.
Make sure you have the big Allen wrench to fit these before you start.
The bolts to the trailing arm are under tension so you have to be inventive with the jack to remove these.
The torque on the lock bolt on the springplate is a huge 181 ft-lbs so you'll need a 'real man's' torque wrench. But if it's not really, really tight, your suspension will sag.
Be prepared to have to do it all twice.

Are you replacing the bushings?

Thanks Ian,
As usual your opinion is helpful.
Yes this whole project is because of the ER bushing I'm about to install.
I replaced the rear "banana arms" last year, so I know what I'm getting into.
I've read many posts, 101, Bentley, etc.
I am a firm believer in doing as much reseach as possible.
2 brains are better than one.
The bolt you are mentioning is the first or second one, the other being minimal height adjustment?
I don't remember torquing it that much. Can do though. I'll check Bentley.
It looks to be as simple as ...
Mark all of the settings.
Remove (jack) pressure from shock (remove bolt).
Remove torsion cover plate.
The other 4 setting bolts.
Re-index
Re-assemble
Do it as many times as it takes
Do you know what angle I should shoot for with Euro setting?

The order:

Jack & remove shock bolt & let it drop.
Reposition jack with it's edge just on the springplate at the springplate/trailing arm junction.
Remove toe & camber cams.
Remove 2 bolts at trailing arm end of springplate (the under-tension ones). Be careful - the springplate can whack down violently once these bolts are out so ease down slowly with your jack.
Remove 4 cover screws.
Now you're cooking . . .

Thanks for the confirmation Ian.
I've found specs on Euro height.
The angle is the difference between the door sill and the plate.
It does not tell me if this is while the car is under load or not.
Does anyone have a link to this info?
Thanks

Rod, I use my floor jack to lift the trailing arm, brake, etc. I use a second jack on the spring plate to ensure it does not pop down unexpectedly. The one I have is a small telescoping jack that is easily adjusted. It never hurts to be safety conscious. Good luck and let us know how it turns out.
