Adjustable spring plates install

[mmasse]

I am about to install factory adjustable spring plate on my 76.

What should be the initial setup for the adjusters?

What I mean is, when I installed the non-adjustable ones, I just measured the angle before disassembly and try match when assembling, but I don't know how to set the adjusters in order to ensure that I have appropriate heigth adjustment when I am done.

Thansk in advance for your help

Set the adjusters in the middle position and install at same angle as old ones. The adjustment is for “fine tuning” so are used for final ride height/alignment/corner balancing.

Opinions may vary. I set mine with the adjuster neutral so I could go up or down as needed.

In the middle like others have said.
Inspect the T-bars, use grease on both ends of the splines, they are marked L & R, make sure you understand the principle behind the 40/44 splines for indexing.
Use antiseize lube for the nuts/bolts.

Good time to upgrade bushings and consider bigger t-bars....

[mmasse]

Thanks for the inputs.
Mikez, I already upgraded the T bars (30mm) and I am installing elephant Racing Poly Bronce bushing...look forward to drive when finish.
Thanks

Now, my rear end will be completed.

30mm Torsion Bars
Adjustable spring plates
Elephant racing PolyBronce bushings.

Look forward to test it

Here is a pic of the spring plate about to be install.

Looks nice, Mario.
For the bolts, use antiseize grease for the torque. (M16 = 177 ft-lbs.)
If washers are used, flat washer goes on first, then lock washer.
Set the shorter torque-plate in the middle (Eccenter lobe on bolt at 3 o'clock) so that the eccentric bolt can be adjusted up or down for the final height-setting/corner balancing.
Stock '76 axles are pretty small to take that kind of power.
What size/type CV's and axles are you using?

[mmasse]

I have stock CVs/axles.
I am in the middel of a tranny rebuild doing all the reommeded improvements to hadle the power (e.g 1 piece retaining plate, reinforced side cover, assymetrical 1ast with beefed up guide and slider...and oil tranny cooling with internal spray bar)

What axles CVs would you suggest?
Thanks

Porsche upgraded the CV's/axles to a bigger size in 1985, about one year into the Carrera 3.2 for obvious reasons.
I don't believe the larger flanges from '85-'86 can be bolted on an earlier 915. In 1987, the G-50 came in changing the set-up again.
I would start a new thread and find out what others have done to get stronger CV's/axles on a mid-year 915.
Stock CV's in '76 were designed for about 175HP, you can see that they are not really for a 3.6 liter with 280+HP.
Also, '76 had stock 15" wheels. If you have bigger wheels, it'll add to the torque exerted on the CV's/axles.
