I'm working out the final bugs in my '87 951 and I have the shake in the steering wheel starting at about 55 mph and it goes away above about 65 mph. I know the solution is to drive faster but the traffic in California doesn't always allow it.

Here's what I have done recently:
- new tie rods (both ends)
- newish steering rack
- steering linkage from column to rack seems tight
- new sway bar bushings
- wheel bearings are adjusted right and appear tight
- ball joints are just rebuilt
- new wheels and tires, just balanced
- new brake rotors
- control arm bushings look ok
- front struts seem ok

The only thing left is the upper strut mounts. Those things are expensive !!

Is this just something that these cars do or am I missing something ?

If you raise the front end of the car and grasp each wheel, there is zero play top-down or aft-fro? You'd be surprised how easily they appear to be tighter than they actually are. BTDT.

Balanced as standard off the car I assume.
In case you have lock nuts, they differ in weight from normal wheel nuts. This weight difference will cause an un-balanced situation resulting also in the shudder as described.
