New 996 owner/Tranny vibration??

Hello all,

I've been lurking on this forum for some time in the cayenne section but finally I just recently picked up a 02 C2 2weeks ago for a fun toy car and have been smiling every time i hop in untill earlier today on the high way I started hearing a light buzzing sound from the clutch pedal but I put my foot on it, it goes away and comes back as I let off. I can also feel the clutch pedal vibrate and would vibrate harder as the rpm rises.
Then after 10mins of driving I feel the car vibrating if I try to push it past 3000rpm! first thought was the IMS, I had PPI done before I got it and the shop said the motor was actually in very good shape and thought it was replaced with a lower mileage motor(90k miles on the ODO), everything check out perfect other then a stiff clutch pedal which didn't bother me.

So far I did NGK iridium plugs, oil change, cleaned MAF & throttle body the day after owning the car. I already made an appointment to have the IMS upgrade put in, but what do you guys think the vibration can be?

02 90k miles with only the following mods
K&n intake
Cat & muffler bypass
Unknown brand headers
Previous owner said the owner before him upgraded with aftermarket cams? but i doubt it lol

Could be a stuck lifter or coil packs. Any CEL lights? Might have someone read the ECU with a code reader.

Have your Transmission Mount & Engine Mounts inspected.

My Transmission Mount was bad causing a vibration above 55mph and when shifting.

I took it to Weissach in vancouver, at first they said it was the fork in the clutch, but after taking the transmission apart. The fork was good.
They said it most likely the way the clutch is worn that caused the vibration and flywheel.
I will know more in about an hour so will report back once its confirmed, as its currently in the process!

UPDATE****

So it was a badly worn clutch and leaking slave cylinder, however it wasn't slipping what so ever.
Fly wheel was ok, said there was abit of heat on it? but they'll clean it up.
I had to replace the clutch, updated fork pivot, slave cylinder, RMS, IMS update = 3600$ taxes inc
