Does the RS LWF need a RS clutch?
So I got the flywheel, bolts, pilot bearing etc. without the clutch. I bought a stock clutch here. Now the mechanic tells me the fork is too far from the LWF. Do I need the RS specific clutch? TIA.

The pressure plate is the same (although the RS part number may be slightly stiffer), . The throwout bearing and guide tube is longer and the disc has a sprung centre. Part numbers are available here if you search or on Pelican in their parts catalog. Be careful to use the correct length bolts and the starter ring gear can be installed backwards (it is notched only on one side).There are also some discs out there which are labelled with the flywheel side on the wrong side.( these should be all gone by now but old stock might still show up.)

So then the starter ring could have been installed backwards? Ill check on this mate. Thanks

If you are using used lwf parts then the shorter flywheel bolts and longer guide tube should be correct already. Compare them to your DMF ones to be sure.. These parts are different than the dual mass flywheel because the LWF is thinner thus shorter flywheel bolts and a longer guide tube. The LWF throwout brg has a 944 number(the most common usage is in a 968) and has longer ears than the DMF one.The thinner LWF moves the clutch further from the trans and closer to the engine.Thats why your mechanic has noticed the throwout you have is too short
The pressure plates are interchangeable from 964 and 993 and twin turbo 996 and gt3. Clamping pressure is lowest in 964 next stiffer is 993 then twin turbo. The difference is about 30% from lightest to stiffest. The RS pressure plate falls somewhere between stock 964 and turbo spring pressure probably very close to stock 993.
You must use a spring centre disc with the LWF to provide some torsion damping. The DMF absorbs some torsion and can be used with a solid centre disc but you should not use that type disc with LWF
The starter ring has a shallow notch,the plate sits down into the notch . If installed backwards it holds the pressure plate slightly away from the disc by the depth of the notch. This will not likely be noticed but will result in clutch slip when assembled.

Depends on how much you spent. If you buy a full kit with LWF and everything expect to pay about $2000 +. The parts places and dealers usually don,t just have a replacment RS clutch kit anyway and will still need to order the 3 parts seperately . The disc is about $375 and the bearing is about $160 you already have the pressure plate.The 3 pcs together are probably $1000+. If your 3 pc DMF kit is still new then maybe you can exchange it.

John/Bill - Will the 996 GT2 plate work? Here is the part no.
996 GT2 plate 996 116 027 51
Troy of EBS Racing has one in stock and is offering it to me. BTW, he has given me excellent service for my other parts:-)
Pls advise so I can order.

That is the turbo pressure plate ( 20-30% stiffer than stock normal asp.car) I thought you already had a plate. You need the disc and throwout bearing. Some people use the turbo pressure plate as a performance upgrade but it will result in a stiffer pedal (Although still not as stiff as the " 999" Sachs motorsport number plate that the turbo guys often use.

I,m not clear what problem you are trying to fix. Your original post said the throwout bearing wasn,t right. You need the longer ear type for the LWF. 9441168001. That is the ONLY cause of your distance problem. That release bearing will still need to be used with any pressure plate IF you are using a LWF.. You also need to obtain the correct disc. There might be several part numbers which would work BUT you need a 240 mm with a spring centre. NOT a solid centre. You need the correct throwout bearing and the correct disc to use the LWF. I don,t understand how changing the pressure plate is the next logical part to change to fix your problem. The pressure plate are the exact same size and shape. THE THROWOUT AND DISC ARE DIFFERENT NOT THE PRESSURE PLATE. Your picture doesn,t show a starter ring gear. You will need one. The DMF has it built in the LMF is a seperate part.

I really appreciate your help in this matter.
