I have been undecided over which way to go with my flywheel for more than 6 months. I think I have read every post on the this site and pelican on this subject. I like the smoothness and quiet operation of the DMF but I can feel the heavy weight on every shift
I also have a vibration above 4200 RPM that I hope the replacement flywheel will correct. My car is a 95 so the MWF was attractive to prevent possible stalling issues.
With all this information, I have decided to go with the LWF. My car is in the shop right now. Stay tuned to find out if I made the right decision.

I suggest -- if you haven't already -- talking to Steve at Rennsport systems in Portland about intake parts that should be replaced while you're in there to reduce the chance of vacuum leaks, as those leaks are one of the significant causes of the stalling. I know I wish I had.....

On the flip side, maybe it will never stall.

95 C4 993, I have read many of your posts concerning the stalling issues with the LWF. I know you are not happy and the stalling drives you crazy. I may be joining the club, but, I took all this info into consideration when making my decision. Your comments are appreciated.
However, I have read many posts in favor of the LWF. I spoke with my wrench, and Steve Wong on this issue and they feel the main drawback is transmission noise at idle and at low RPMs. Everything else is a plus.
The flywheel and clutch is being replaced without removing engine.
Stay tuned

The stalling doesnt happen that often but when it does happen, I just want to put my fist through the windshield. It's more common with the A/C or lights on is what I have noticed in the past several years.
The transmission noise doesnt bother me and I dont usually hear unless Im pulled up next to wall---like a drive through. Its sounds like marbles rolling in a tin can. There is a noise that comes between second and 3rd gear---its like a low gargle.
The advantages, feel, and performance are great but in my opinion. That damn occassional stall is haunting.![grr](https://rennlist.com/forums/graemlins/cussing.gif)
BTW--the only fix I havent tried is Steve Wongs chip but I did speak to him a few years back about it but I've gotten to the point that I dont want to waste any more time with it. I probably have thousands of dollars in personal time vested in it already.
Good luck and keep us posted on how it turns out.

My stock '95 with DMF idles ~750 according to the Tach, no stalling issues.
Is that normal idling for a 993? I intent to clean the ISV as part of maintenance anyway.
With LWF installed, what idling RPM can be expected?
Would it help to open the butterfly setting just a little? I assume there is an adjustable throttle-stop?

As suggested - call Steve Weiner.
Stalling with lighter flywheel can be stopped with a change to a purpose calibrated ecu chip.
I have a RS camshafts, Andial sports clutch and Euro RS flywheel with Rennsport Systems engine management chip designed by steve Weiner for this configuration - never stalls.

oh, I forgot the Billy Boat stainless steel exhaust headers.

Without making any other changes like chip, cams, etc., where does the idle RPM ends up when doing ONLY the LWF and clutch?
Would love some answers from people who installed LWF without doing anything else.![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
And, has someone tried to move the throttle stop to increase idle slightly?
Please, just people who ONLY changed the LWF & clutch but nothing else.
