Now I realize why they used the liquid filled mounts.
Leading evidence: 'Fill mounts' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check transition mount, odds are its due' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Will have all the seals replaced (RMS, Input shaft, IMS).

Just replaced my motor mounts with the Rennline adjustable mounts.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have leaky seals on the trans side of engine. Will have all the seals replaced (RMS, Input shaft, IMS). Thinking of upgrading to an aluminum flywheel and stage 1 spring clutch. How is the drivability with this package? Is it worth the extra cost? My flywheel will probably need resurfacing as I have got the car stuck and the clutch slipped one time. Also thinking of IMS bearing kit. Had replaced it with the cheaper Pelican retrofit kit about 40K miles ago. Would the double row for single kit from LNE be a good choice? This is on a 2001 C2 Cab.
The double row pro from LNE is a good choice, the Solution is even better. My opinion on the flywheel/clutch - stay with the OE Dual Mass flywheel and clutch components. A lightweight flywheel and spring clutch is NOT an upgrade. The dual mass flywheel is designed to reduce harmonics that affect the crankshaft. Some M96 engine experts do not recommend lightweight flywheels and will not install them. You will be way better off in the long run to use an OE dual mass flywheel and clutch components.
I switched from a LWFW back to dual mass recently. For everyday driving, I prefer the dualmass flywheel since it is quiet and easier to drive in stop and go traffic. For sports driving where the engine
spends most of the time in the higher rpms, the engine feels noticeably more responsive with the LWFW, but your transmission will make rattling noises in neutral, and misc. strange noises under some conditions.
If you still want to a LWFW despite the warning, I have a AASCO LWFW for sale if youŕe interested.
Just did a clutch last week and went with an oem clutch kit and flywheel based on issues I�ve read about with the lwfw. Also did an AOS and dual row retrofit imsb from LN at the same time purely out of pm given it�s The right time to do with the tranny split. Yes the solution is a better option, but given the imsb is only one of many modes of failure I did not wish to spend the extra $1500-2k given the cost of the kit and lack of authorized installers in my area� would have required me shipping the car off, so I�ll just plan on servicing it again in 5yr provided I still have the car.
I went with Assco LWFW and Sachs Stage II sprung disc and Sachs pressure plate.
Yes it rattles in neutral.
I enjoy the performance from it.
Not all agree on this modification, buts that's ok, it's fine to have different points of view
I never recommend installing the LWFW. As adamant as Porsche is about saving weight, and doing every thing they can to keep weight or shave weight, I believe the 13 extra pounds is there for a good reason as many has explained. The noise alone is enough for me to not recommend it.
But if you're ok with the noise, and know all the risks, I have no problem with anyone doing it. I have a friend who I built a 3.4 big bore (3.8) for and he knew all the risks and drawbacks, so we put the LWFW and sprung clutch in. He was so happy for a while and has put 30k on it, but I feel like whenever the opportunity arises, he will go back to DMFW !!
Had a LWFW that had been installed by the previous owner, one of the first things I did was remove it.
Performance and response - awesome
General driving, noise, rattles and takeoffs from stops, potential engine harm - not great
I have a used Sachs sprung clutch disk that can be used with the ASSCO flywheel if you're interested - they retail for a fair bit.
Just replaced it Saturday. Was cracked and need replacing. Now no shudder when I let the clutch out in reverse. Used the AGA tool and did it while trans in the car.
Think I will stick with the stock set up. Just replaced my motor mounts with the Rennline adjustable mounts. Used the sport bushings. I got more vibrations and rattles than before. Not sure I would like more of that for a DD.
Mine will be done in the next few weeks when the diff gets upgraded. Had in the Proflex "race " mount inserts, wholly vibration was like driving a cup car or F2000 great on the track, switched to the "street yellow" much better. Will probably run the yellow in the new mount.
I probably should have put in the yellow, but I do like the improved performance feel. Very glad I did not go with the red! Now I realize why they used the liquid filled mounts.
