Adjustable spring plates

It has been suggested (by a mechanic) that I might want to consider adjustable spring plates for my 83' SC.

I would welcome any input about the performance of this upgrade (is it worth it, not worth it, etc...)

And any recommendations of adjustable spring plates (brand or manufacturer) that are great and well worth it, or ones that are horrible and I should stay away from.

Thanks

You should already have factory installed adjustable spring plates.

The only advantage is when you setup and corner balance the suspension.

yeah the aftermarket plates speed up the process of rear suspension changes. Are you adjusting your rear suspension ride height, camber and toe a lot?

For extreme wheel fitments where wheel back space is critical the location and configurations of the trailing arm adjusters can be important.

stock and the various aftermarket versions will differ in this respect.

I did a complete suspension refresh in my garage last winter, very happy with the results. I went with adjustable spring places b/c of the savings that I'd realize for the alignment done by my local wrench. Doubtful I'll adjust the height again, but now I have the option and the difference in price was negligible. I don't think I would have gone adjustable if I had paid someone to do the suspension work.

+1 - I did the same. Not hard and learned more about the complete suspension. I went with Sway Away adjustable spring plates (and Elephant Racing poly-bronze all the way around). It's tedious, but not too hard to do your own "string" alignment with the aid of some simple laser levels from your favorite big box home improvement store.

maybe because its an issue with the rubber bushing?
these rubbers normally are vulcanized and sold by porsche as one piece only.
no mechanic has fun removing the old rubber.
so he suggests the part as is.

Making ride height changes in the rear is a real pain in the rear. If you have adjustable spring plates, it cuts the time and number of attempts down. I'm no pro mechanic, but I doubt they get it spot-on the first go around either, and I would expect a discount with adjustable plates. I don't think any mechanic would profit from you having adjustable spring plates unless he was selling them.

If they're coming off for other reasons...I'd replace them. I got mine from Elephant (just the splines) and they worked out well.

That's right....I think you nailed it. The height adjustment in the rear is difficult and time consuming. There is some adjustability with the stock spring plates, but apparently not anywhere near as much than with the aftermarket adjustable spring plates out there. I think the comparison would be 1/2" with stock vs. 2" with aftermarket adjustable spring plates.

I have a set of 15's I am running right now, but I also have a set of 16's that I may want to go back to at some time. The thinking is, that if I have the adjustable spring plates, I will be able to do that myself without too much difficulty rather than having my mechanic reindex the torsion bars again.

I was not under the impression that the aftermarket allowed that much adjustment? I have not played with them.

In any case once your suspension is close the stock adjustment should be plenty.

Remember, if you are adjusting the ride height you may need an alignment. Is that something you are comfortable doing in your garage?

I have learned that whatsoever versions of springplate there are, the adjustment is just kinda finetuning (max 10mm up or down from zero). whereas you actually dont want to go that much, as it will change the rest of the wheel allignment in relation.

It is NOT made for the actual ride hight-setup that has to be done by setting the torsion bars right. The torsion bars have inside to ouside different toothing, which, by rotating, allows you to change ride hight up or down various inch.

this graph is in German, but you can guess the idea of the bars. you allways have to envisage the inner and outer toothing in relation to each other.
