Getting rid of the stupid dual mass flywheel

Cautionary tale: clutch engagement will be very low to the floor (same problem exists with LS2 slave + Katech spacer). I've been limping along this entire winter with this situation, and will be having a custom 1/4" shim made to space the LS7 slave cylinder out a little more.

Also, how many of you guys with the RAM flywheel installed have NOT had a tune and do NOT have other significant power-adding mods?
I just had a conversation with East Coast Performance today, and he confirmed my belief that most of you guys probably had some tuning done after the 19Lb flywheel was installed. Without a tune and/or other mods, it's his belief (and mine) that such a lightweight flywheel would probably have some pretty significant effects on daily driveability.
Concerns go beyond just those involving getting the car moving from a standstill too. There are also potential issues with sudden stops, where the engine might not be able to "catch" itself, thus stalling out.
If there are folks out there with the 19lb flywheel installed on a basically stock V that is still running on the OEM tune, I'd love to hear your experiences.

Don't see what the issue is with the light flywheels, I have the katech ls9x clutch and flywheel combo. The flywheel is 12 lbs and no tuning other than turning my cags off, I haven't had any issues with driveability. Unless the twin disk clutch compensates for the issue the ultralight flywheel hasn't caused me any grief. To be honest it drives much better than the stock setup, granted that doesn't take much.

Replacing mine now.
Is the Dual Mass unit two pieces?
I sure hope so, as it is twisted and I cannot get to the bolt holes.
When you look at it from underneath it looks like the out layer is coming off, but it was late and I wanted to get at it in the morning with a fresh set of eyes.

Gents, forgive my ignorance and general "noobiness" on this board, but I read this thread and it sounds like y'all are talking about replacing the CTS-V dual mass flywheel with a setup from an LS7... But I thought that the big issue was that the crankshaft on the CTS-V (I think that we're talking about the LSA engine?) is set up for 8 bolts? And I thought that most other LS-based flywheels were not.... I ask because I'm installing an LSX454 in a vehicle and it utilizes the 8 bolt flywheel, therefore, I'm having the CTS-V clutch/flywheel installed, which y'all sound like you're removing just as quickly as you can.... Can anyone help clear up my confusion? Thank you.

OK, so all of you who are getting rid of your dual mass flywheels are 6-bolt guys.... I need to bone up again on my Cadillac, somehow I thought that "CTS-V" = LSA--sorry!
Just in case I'm not happy with what I end up, is there anything out there for the 8-bolt guys to do when it comes time for clutch/flywheel replacement? Thanks again for the help.

Thanks! Got it now. I did do a little
and looks like Lingenfelter is offering a flywheel and ZR1 clutch setup for this crankshaft.... I'm hoping that I'll be happy with the dual-mass setup for a little while, though. Sorry for the thread hijack.

So for a bone stock 05 V is this considered a good clutch set up? I will be grabbing a clutch soon for my wife's Cts-v and trying to find the most cost effective replacement. If I can make it drive a little better for her all the better. How is the pedal feel on this after getting some miles on it? Did it ever come up off the floor?

One thing I'll mention. Take the clutch assy and bolts to a machine shop and have them balanced. Not expensive at all...and both the LS7 clutches needed some work. I do that on ALL clutches...even high end pieces for my race car need work...so it's money well spent.
