While You are in there mods Clutch Upgrade
 

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.

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

when you guys do when u take off tranny.. other than rms and ims any other seals or stuff that is easy to do with tranny off?

Do the AOS. Not "easy" but easier to do with the trans out (you don't have to remove the intake).

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.

Check the transition mount, odds are its due for replacement.

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.
