NYC993

I know the topic was discussed to death but I will add another data point for any new owners out here who might be on the fence like I was.

I have 98 C4S and it was time for new clutch at 80k miles. Mine was slipping when in gear. In short, LWFW is a good upgrade and I would do it if new clutch is needed. I don't think it's as mind blowing as others claim, so If you have regular clutch I would not run to get LWF, until you need new one. The biggest difference is having the new clutch itself. Low point of engagement and no slipping makes it an upgrade in itself.

The engine spins a bit faster, but again not as noticeable as some describe. I did 6 to 5 to 4 to 3 at 80mph and it's easier to rev match, even if you don't match the revs perfectly, light fw makes engagement smoother. The car feels a tiny bit faster, but it can be simply due to clutch not slipping anymore and me being more aggressive.

Also, I don't experience loud gear box chattering that others describe. I have slightly louder chatter if you lug the engine (i.e. in 2nd gear under 2k rpm), but I had that with reg. fw. Also when tranny oil is fully warmed up, you can hear slight chatter at idle in the cabin. Outside it's not noticeable due to exhaust sound (I have stock motorsound).

I have zero stalling issues, the ECU actually saved it couple times when I was about to stall (still getting used to the having brand new clutch).

My impression as well on the C2. No chatter at idle warm or cold. Slight chattering when lugging engine <2k rpm 2nd gear. Love the quick rev!

Chatter for me, particularly when hot but it is supposed to be this way.

Plenty chatter when hot but gearbox has done 160k miles. Gun it in first and second you will notice the difference in acceleration. The car is approx 300lbs lighter than standard anyway so may be more noticeable in mine. (Sunroof delete, RS interior, etc.)
Not a comfort option imho.

Just installed my LWFW and RS clutch kit from Steve W. The difference is very subtle, but definitely a very nice upgrade.
My experience is very similar to NYC993. A little chatter at idle and low revs in 2nd & 3rd, but gear engagement is very precise and tight.
Love it!

My result was more than subtle. No chatter at all. 764PP and 4.0 disc. Very pleased that I did it. Boost comes on much quicker. :-)

LWF and RS clutch alone is subtle. I enjoy the combination of those two along with the re-gearing. Those three items together make the car more responsive especially on the lower end and in the middle gears, 3,4,5.

My LWF does chatter at idle but it goes away when under load, as it should.

Good upgrade. Should be good for another 80k+, enjoy.

Thanks for the test drive...that made the decision very easy.

Thank you for the input. While I don't have slippage yet, the engagement point is very high and I might consider doing the clutch on my car. A quick question: how would one go about finding out if a 993 has a LWF? Is opening it up the only way? I am approaching a year with the car and have little history of what has been done to it... Nor does the PO who had it for about 3 years and 50k miles.... Thanks!

LOL - you better not drive a car thats been re-geared too!!!

One way is you would have slight gear chatter in neutral when gear oil is warmed up. The chatter disappears if you depress clutch. You can also feel it in the gear leaver. But it's very slight.

If you drive another 993 that has LWFW you should be able to tell the difference if you have DMF.

I have yet to do that.

BTW, not sure if you saw/heard, I met the owner of your old targa. We found out through RL that we work for the same company.
