Anybody:Tune up help for $$$

I don't think the spring plates on the 1970 S are adjustable.  The 1986 however is adjustable with the factory plates. You can adjust the ride height on the 1986 without aftermarket adjustable spring plates but of course they make it much eaiser.  The eccentric bolts on the spring plates have a total adjustable range of around 3/4 inch. They are great for fine tuning, but to make any serious ride HEIGHT change you must re-index the t-bars (thats the fun part).  Turning the eccentric bolts on factory adjustable spring plates requires a special wrench. It is a regular hex head, but it is thinner than a standard wrench. The wrench must fit between the spring plate and the inner wheel well, a standard wrench is just too thick and won't fit. The wrench is available from most major Porsche parts supliers.
