Throttle response is better addressed with a tune

If your Z is only seeing street duty I would recommend installing the South Bend Stage 2 daily clutch and flywheel kit with quiet option. This clutch and flywheel will last longer than the Genuine Nissan OEM clutch and flywheel and it is more durable/stronger as well. Joe certainly knows his stuff and thank you again Joe for helping out the Z community! Install a Z Speed Performance CMAK Kit as soon as possible if you already have not before it’s too late and your Z ends up riding on the back of a flatbed tow truck lol. Also this is a great time to change your transmission fluid if you have not. Definitely install a brand new flywheel at your mileage.

The weird thing is, I've had my car since 50,000 miles and have not once had an issue with my CSC. It may be possible that the previous owner did the upgrade as it did come with a few mods when I purchased it, I'm now at 112,000 miles and have never had a problem with the CSC giving out..
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.

If Seb looked at it; you’ve taken it to the right place

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?
