914 ride height?/raising rear/trailing arm ideas? Options

[slugmika]

I'am going to raise my rear suspension pick up points and would like to know what should be the ride height?
I found that front shoud be 108mm from torsion bar center to spindle center.
What is Porsches recomendation?
I know that some of you have raised pick up points, have you used the factorys specs or what.
How much have you raised those?

And finally, is there any poin to make the stock kind of trailing arms? I have allready made a jig with stock trailing arm dimensions. Those would use stock bearing hub but otherwise made of tube. We would use uniball's rather than stock kind of bushings.

Car is now on a table and it would be easy to make allmost anything, so if you have good ideas feel free to share

Thanks
Mika
