Cliff - I think his problem is vibrations he feels in steering wheel and seat of his pants - not the speedo needle.
If " In fact, we have spun the wheels on the car and they spin out of round" is true then you'll never get smooth ride with egg shaped wheels. You can have tires pulled off and they can spin the rims alone on the balancer to see if they are out of round. You might find 2 are better than the other and use those for the front. Like Calmotion said may be okay for back - or for a garage decoration. At price I assume the EMPI Fuchs aren't scrutinized by German Fuchs TUV standards - just round enough.
You mentioned lug centric. Are you using the right lug nuts? There are round ball shouldered and tapered acorn bolts/nuts. Are you using bolts or studs with nuts. I've been looking at the CIP1 Fuchs with 5" backspacing http://www2.cip1.com/ProductDe...=ACC-C10-6649 - and in one place it says "These wheels are machined to use tapered 60 degree acorn style mounting nuts or bolts." But if you click on wheel hardware for that wheel it says "C32-6655 - CHROME PLATED 14MM WHEEL BOLTS WITH BALL-SEAT - WITH 1-1/4 INCH THREAD - 4 PIECE SET" http://www2.cip1.com/ProductDe...ProductCode=C32-6655
If you have the wrong nuts/bolts then they aren't making much contact with wheel and could be moving around. Maybe pull a wheel off and put some paint on the seating part - and see if it makes full contact with the wheel. Might be obvious - but as you put a wheel on do so in a cross diagonal pattern (not around the wheel). This will seat wheel properly as you apply the right amount of torque with a reliable torque wrench. I avoid torquing wheels at places that use a rattle air gun - even with the supposed torque extensions. Old fashion beam torque wrench for me.
