RS clutch

Hi Andrew - yeah no problem though I have to give you my experience of the RS LWF AND Clutch together as I got them a pair. (in fact not sure you can get them seperately).
The clutch itself didn't 'feel' that much different from my then very worn and slipping standard clutch - in fact it felt lighter with a marginally more severe bite. The main difference was in the sound as you took up drive - you get the 'coffee grinder' noise as you engage drive and even when drive is fully engaged (ie no clutch) you get the coffee grinder up to around 2500rpm. I believe this is because the RS clutch doesn't have any rubber damping.
Also when the car idles in neutral without any clutch there is a knocking sound from underneath the car - it doesn't do this when clutch is engaged, this is by design too aparently.
The light flywheel enabled the car to rev up quicker especially in the lower gears - in fact when I first drove the car after fitting it was startling how it would 'pick up' compared to the standard FW. This, plus the weight saving is really why I had it all fitted. Engine response also benefitted greatly from the LFW in gear - the car would react like a racer when planting the foot down in the mid or upper parts of the rev range.
The LWF also affects idling, especially from cold - my varioram car didn't stall though I have heard some older or non-varioram cars may have stalling issues with LWF. When very cold the revs would rise then dip to almost stall then rise again in a few cycles before settling down.
To summarise Andrew, IMO the kit does change the character of the car and if your aim is to make the car a more focussed, race style car then the change is for the better.
Ideally I would have wanted all the lightweight benefits and the stronger clutch without the noises - they aren't obtrusive but certainly remove refinedment from the driveline.
My generalisation would be:
I would only do it again if I had a C2 and did quite a lot of track days - looking back it didn't suit the GT nature of my 4S that well.
On saying that IMO it's one of the best performance improving mods you can do to a 993.
edit: is that too few words Andrew? I could keep going.

I had a light weight RS clutch and flywheel fitted about 30,000 miles ago. Absolutely no difference to the driving just that 'noise' when pulling away in low gears under load and idling. I would certainly recommend it and you avoid the dual mass flywheel falling apart when its gets too old.
