For a while now my car has had a slight vibration that you could feel while revving the car in the 2500-3500 rpm range. Recently it's gotten worse where you can feel it while driving around 3500rpm and above. It's rattling the car(I think) and I can feel it through the shifter. Does it sound like it's the TT bushings, or could it be something else?

Car is a 99 coupe 6 speed. Bolt-ons, spec twin clutch, B&M ripper shifter, RPM Stage IV trans, RPM stage II rear with 3.90's.

You didn't specify how you rev'ed the engine. If you had the clutch pedal to the floor/shifter in gear and felt the vibration, it's not the TT bushings (with clutch disengaged/shifter in gear the driveshaft is stationary). If you rev'ed it with the clutch pedal up and shifter in neutral, then it could be the TT bushings. Please post how it was rev'ed.

When my bushings were shot, I didn't notice any vibrations. What I did notice was the driveline being "notchy". When I put the car in any gear (while in motion) and the clutch engaged there was a very noticeable "clunk", like there was slack somewhere.

Car is in the body shop right now, but I believe with the car in gear and with the clutch pressed to the floor, when I would rev it this is when most of the vibration would occur. I can also now hear a rattling around 2k rpm when just cruising and letting off the gas.
