Good Vibrations
If it is pure road speed related vibration, then look to out of balance rotating equipment.
Felt as overall vehicle vibration (seat of the pants) is usually the rear axle. Felt in the steering wheel, the front.
On our Porsches I've seen bent rims, out of balance/faulty rotors, axle shafts, bad bearings.
With engine rpm vibrations - engine load and revs, we've seen engine issues like mounts, improper mixture, etc. or driveline such as flex plate, transmission, driveshaft.
