The 944 bearing has longer fingers that connect to the fork. The overall height of the LWF setup (or length coming off the end of the motor) is shorter that the dual mass setup. In order to correct the geometry a throw out bearing with longer arms is needed. Without this, the fork will be WAY over extended (angled towards motor on the one end and way too close to the slave cylinder rod on the other). Not sure it was even possible to do it wrong like this, but guess you can.

I really appreciate this pic and input
fyi; upon initial install of lwfw and replacement of bearing following, setup worked great for about 15,000 miles, then the following: 1. buzzing pedal at around 5-6 thousand rpm shifts 2. inconsistent engaement/disengagement points points 3. vibration

BTY: I'm thinking that the growling expected with the lwfw will be less with the correct set-up PS how did u figure all of this out?

The parts have been around forever. Whoever did your install (sold parts and did the labor) screwed you. The PET from the early 90's had all of the proper parts listed.... They have not changed...
Also check your input shaft splines and make sure you have the guide tubes as mentioned earlier in this thread.

No photos of dual-mass setup throw bearing, we replaced the bearing because we were in there and I found it to be a bit noisy when spinning by hand. The bearing you remove should look the same as above but with shorter "stubby" fingers if not the proper 944 part.
I didn't figure anything out, that's the way I got the car, but since P/N info is in the PET, it's not some obscure knowledge. Probably something that the guys working with stock cars are just not used to however. Remember, the RS never came to North America.
BTW, I had a bit more chatter than normal when releasing the clutch pedal. Turns out one of the needle bearings for the fork pivot shaft was missing (gearbox has been in and out a few times prior to me). What this means is that the fork/shaft were a bit crooked so I was probably not getting a "clean" release/engage. It's much better now. Just a heads-up.
Good luck.

u need to buy ALL the parts.
i sourced a set of LWFW from bob long ago on one of my 04gt3. he provided EVERYTHING. flywheel, clutch, pressure plate, guide tube, throw out bearsing and even bolts. everything went on perfectly. i like one stop shopping.
