Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Suspected cause
If its the steering wheel suspect the front wheels or discs.
Leading evidence: 'front wheels or discs' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'front wheels or discs' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Recommend action' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
Having the wheels/tires Road Force balanced is my recommended action to confirm or eliminate a balancing issue.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have a vibration at about 65+ MPH. The whole car shakes, and I can feel & see the steering wheel shaking. Not terrible, but annoying. Any tips to help pinpoint the cause?
Could be the follow (but might be something else)
These are my top 4, but I might have overlooked something
1.Cold tires which have not come up to temperature
2.Flat spot on one or more tires, especially if older
3.Imbalance of one or more tires (suggest road for balancing)
4. Suspension issue
Wickedgood911's list is a good one. If the problem occurs after you've been driving for a while, cold tires and flatspots are less likely and an imbalanced tire/wheel is my top contender. Having the wheels/tires Road Force balanced is my recommended action to confirm or eliminate a balancing issue.
Good luck.
Bent wheel is bent @ any speed.
65mph is starter speed for most wheel & tire assembly vibration issues.
Examine the rim edges inside & out of all wheels to see if you can spot any bends, if so start with the worst one 1st.
Have wheels checked, after years of searching for a solution to that same problem, I had two sets of wheels spun alone, 7 of 8 had visible wobble/run-out. RF balancing was masking the problem because tire shop wasn't informing me the wheels were out of spec.
For me, good set of true 993 turbo twist (had two bad sets of wheels) and ditched all my spacers. First time in stock (well RoW sport) trim since i have had it. Extremely happy now, up to 130mph.
Wheel balance is normally kicking in at 80mph. Below that and you shouldn't pick it up. If its the steering wheel suspect the front wheels or discs. Rear wheel vibration is more often felt through the seat of your pants than at the steering wheel. At 65mph I would suspect discs or suspension or wheel tyre faults have it balanced and get it checked round by a knowledgeable person as it seems low speed to me to get vibes...

Not normal. Do you have spacers on your car? I have had mine up to 150mph and steady as a rock all around (no spacers). Same feeling as 50mph. First..Get the wheels balanced and tracking set up. If the car reacts the same afterwards you can look further into the matter.
