Should probably get it checked out before dishing out money on a CSC elimination kit if I already have it. Is there any way to check without taking everything apart? Sebastian @ Specialty Z tried looking under the car but could not tell.

The CSC elimination kit relocates it outside the transmission bell housing so, if you had your Z inspected by Seb and he could not find anything then it is possible that you may not have the CSC elimination kit installed on your Z. The Genuine Nissan OEM CSC failure is a gamble more the less a roll of the dice if it will fail or not?? It is possible the Genuine Nissan OEM CSC could have been replaced before you purchased your Z. I replaced my Genuine Nissan OEM CSC four times before I finally had my Z Speed Performance CMAK Kit installed. Replacing the Genuine Nissan OEM clutch and flywheel the first time was something I really was happy that I changed my flywheel had light burn spots on it and my clutch disc had a lot of wear on it. Shifting will improve after you install your new clutch and flywheel. Install the Z Speed Performance CMAK Kit if you don’t have one.

I got Zspeed 20LB flywheel and Stage2+ clutch with quite option, along with a Ebay heavy duty CSC. My feedback:

1. Solid flywheel has pros and cons.

PROS: engine revs noticeably faster and there is less vibrations (if DMF is worn it will vibrate). Car feels much more alive and is more exciting to drive.

CONS: the clutch engagement is harsher, without DMF there is no damping or cushioning of clutch engagement so you def feel if you let off clutch too fast. Fuel consumption goes up, this is debatable, however I did notice it go up by 15% because it funner to drive and engine wants to rev. Tranny rattle from 1000-1500RPM.

2. Stage2 Zspeed clutch has more pros then cons

PROS: My Z is pushing about 320WHP and stock clutch would slip at drag strip in the second gear. Stage2 grabs like a MOFO and with SMF the car picks up like no tomorrow.

CONS: Clutch pedal is about 25% heavier.

What is DMF and SMF?

would you guys take the CMAK kit to be installed at a transmission shop or an actual dealership??? or maybe even a high end tuning shop??? not sure how easy of a job it is.

It's not a difficult job. But any idiot tech can screw it up. I'd avoid the dealership for installation any aftermarket parts unless you have a good relationship with the tech doing the work. Find a competent shop - preferably one that has done the same job with the same parts on another Z34.
