How does RS clutch differ?.. I heard it makes a rattle sound.. Can anyone enlighten me?

Not the clutch, but the flywheel. RS uses a single mass unit while regular GT3 a dual mass part.

Regardless of the 3.8 RS PP design, sticky hoosier tires and ham-fisted shifting, that's a big part of the problem.

More power, Lower gearing, and a lot more shifting is also part of why the .2RS clutch/TO bearing sees accelerated wear compared to the .1GT3/RS and .2GT3. It's a fact. The more you shift, the more wear that takes place.

What's the last cupcar with highest hp/trq rating using a manual transmission? Was it 415 hp? Don't remember. Mike

I was going to do it while the motor was out for exhaust cam actuators replacement but dealer advised me the warranty would be void, will wait until warranty expires.

hi guys .. so as i read your discussion the OEM GT3 normal clutch kit and DMF ITS better for long life of the clutch plate !

typically the LWFW only rattles (noticeably) when at idle, due to the single mass not "ironing out" slight variations in engine rpm which casues the chattering...

RS clutch is Much, much easier to depress
LWFW is noiser

Have 5K street miles + AX and HPDE seems fine

Just done a full RS 4.0 kit from Suncoast to my 2010 GT3. I did a ton amount of research and my conclusion is don't do it with any 997.1 GT3 as the pulley won't hold. Confirmed from Suncoast and Alex from Sharkwerks, for the 997.2 they used the same pulley as the RS so it is less likely to come loose. To be sure, you have to check your pulley whenever you have a chance to make sure no bolts are backing out. The problem with the LWFW is that it rattles, vibrates and make more noise than the dual mass. More vibration looses the harmonic balance and will vibrate bolts out of the engine, but it is a very slim chance as less restrictive exhaust and running the engine itself vibrates.

My final thoughts are the performance is mind blowing after the install. You have more pull in gears and the rev match felt like a another level, now it feels like a RS without the crazy wing and wide body. But in return, you get a dishwasher type noise at idle and still remains until 3k rpm then it goes away. You also get way more vibration like a truck while at a stop as well. Clutch is more precise and no room to play which is less streetable than the dual mass. (Jerks more)

^ overall would you say you are happy with the decision? Im about to pull the trigger.

Just an update - approx 27k miles later and it's great, I'm still loving it. As others have stated, more NVH from the LWFW and some chatter but nothing unbearable. The rev matching and overall free-er revving is very noticeable.

Would recommend to anyone.

Most of the LWFW problems were in the 997.2 engines. The 997.1 seem to be fine. Just also get the matched pulley to go with it.

who did you end up buying it all from?

complete list of parts used?

Suren27

Was done at the dealer - will have to check if I still have the parts list. Otherwise I think suncoast/sharkwerks should be able to assist.

I bought mine from Suncoast, they sell a kit. Local shop, where I had it installed said they could not beat the price.
