However one thing to check is your fluid filled engine mounts.
Leading evidence: 'Fill engine mounts' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'mods' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Adjust angle of the seat you can reduce the shaking' (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.

Replaced the mount and she's smooth at idle again.
Adjust angle of the seat you can reduce the shaking

If you adjust the angle of the seat you can reduce the shaking.

Furthermore, the filters EvoMS is using now are not oiled.
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.

If no one is sitting in my passenger seat while the car is idling, the seat will slightly vibrate and shake - this is especially noticeable on the seat back and the seat belt buckle. The whole car slightly vibrates at idle, including my seat, but it doesn't shake because it has my fat butt in it.
In fact I notice that my idle isn't butter smooth, and that it "searches" about 50 RPM up or down. It started doing this after the EvoMS intake was installed, which I attribute to the removal of the air-straightener for the MAF. My car is also GIAC chipped, but they didn't change the idle at all.
Perhaps this is just normal? It's not annoying, just seems slightly unrefined. I highly doubt my MAF is bad, as the car only has 16,000 miles on it, and the MAF was extremely clean when I looked at it and installed it in the EvoMS intake. Furthermore, the filters EvoMS is using now are not oiled.

Streaking windshield wipers are also a sign of impending IMS failure.
In fact writing on the Rennlist BB is a sure sign of impending failure.
About the vibration it is probably the mods. However one thing to check is your fluid filled engine mounts. They can fail (oil leaks out) causing more vibration then "normal" to be transmitted through the chassis. Sometimes you can tell by looking at the the exhaust tips when the car is parked on a level surface. The tip on the failed side will often be noticably lower then the other.
Mine does it. It bothered me at first but now I kind of like it--it's a link back to the days when 911s were a little more raw.
I can do without the useless A/C and oil smells of yesteryear, though.
Mine does as well. My Boxster S did it too, straight from the factory. I kind of like it. Sort of says "this car is for drivers -- passengers are about as welcome as functional cupholders or a good radio."
