we have heard much about teh pros of LWF /RS clutch set out. What about the things you dont like about LWF

I dont have stalling problem with my 95 993 but what i dont like about the LWF is the reduced torque and steadiness of the engine at low rev, esp in city driving and stop and go traffic. Reversing the car is relatively more difficult

one would have to rev up after the clutch is engaged, and car could no longer move along smoothly at idling rev with clutch engaged.

Thats why i plan to move up to MWF.

AS to the dual mass flywheel, i have no idea how a new one would feel on my 993 which was bought used. But with my new 987 with dual mass flywheel, i dont thank it feels like an "elephant" though the contact point is relatively vague in comparison. our stock 993 can manage 0-60 in mid 5s and is a LWF or even MWF really needed?

I am considering if I should replace my LWF with a MWF or even a new OEM flywheel. Just some thoughts at this moment.

is the OEM flywheel much more expensvie than a MWF? any good parts dealers guys would recommend?

During 1,000s of miles of mostly urban driving I've experienced none of the problems you've described. Mine is a '96 so maybe that explains our night & day experiences.

Con: The revs build so fast you're into speeding ticket sooner than with the stock DMF.

IIRC, cost wise, the lwf is < OEM < mwf. I agree with you that it is a bit more difficult to drive, at least at first. I assume that once you get the hang of driving with the lwf, it won't be so difficult. As for the noise that some complain about, I really like it.

i doubt if the car would be faster, or reaching 60 miles or 100 km in quicker time with LWF installed. There had been discussions here before and it seems that most ppl agree that with the LWF, the engine revs more freely (both up and down) but it does not necessarily make it faster.....

I was having trouble reconciling this issue in a prior thread and someone posted this:

Pretty compelling and does in fact state that acceleration is improved.

I love my LWF. I am not a scientist or an engineer, so I can not give you hard evidence. Does my car rev faster, you bet (tested side by side with DMF 993). Does it feel like it accellerates faster, and more easily, you bet. Would I ever go back to the DMF....NO WAY!

Compelling is an understatement. Great read.

ANDIAL takes the LWF and adds some weight to it...this was done to address problems with the 1995 OBD I model. It aint cheap, about $900 as I recall.

The only disadvantage I have heard of...whem the car is in neutral, at a stop, you can hear the gear sets rattling around. If you son't like the noise, depress the clutch and it goes away.

The LWF does improve accelleration. I did timed runs before and after.

Yes the LFW is harder to live with when compared next to the DualMass....yes it is noisier when at idle and accelerating in 1st n 2nd gears, yes you need more revs to move away smoothly, yes you are correct reversing can no longer be done at tickover, yes it is stall prone in MY95 cars, but.........the engine revs faster, it accelerates faster, it makes the car feel more alive, it makes a great noise, it costs less if you are doing a clutch change and need a new Dual mass........really it is a very individual thing.....some will love it (I do most of the time), some will hate it......suggestion to those thinking of doing this.....drive a comparible MY with one installed.

I had the LWF on my previous 993, a '95 model. It stalled now and then: the revs would just drop and the engine turnoff. On my '96 model, no problems at all. Just benefits.

I've got a 97 C2S with the LWF and RS clutch.

The car seems to run just fine. It doesn't feel or chatter like most LWF's I've had experience with. In fact, it is fairly OEM as far as I'm concerned, however I have never driven a 993 with a DMF.

But I'm able to get the car to take off from a light fairly well. No chatter, very smooth engagement. The quickness in off-load revs had me a bit surprised at first, but just needed to compensate with my driving habit.

The LWF does have one caveat I do not like: It will stall the car in certain situations for me. If I'm turning the car, as if parking into a spot at full lock, and I depress the clutch and put her in neutral, the revs will fall (very quickly) and sometimes do so in a matter that gets below the idle and occasionally stalls the car. It's not a perfect science, and in fact when I tried to force it to stall (in that situation to show a tech) I couldn't get it to work.

I like it. Getting into the 997 after driving the 993 is a very different world. A great one, don't get me wrong, just very different.
