Hi guys,
One for the more technical PHers. Which clutch would be best for my 996 turbo x50 tuned to 673bhp. Do you think the 964 RS would be okay or would you recommend something else.
The guys at JZM will be able to tell you exactly what you need. They fitted my 997 Turbo with a good quality upgraded clutch.One for the more technical PHers.

Sachs should would fine
Would I notice any difference in the feel of the clutch. Don't want to fit anything that will make the car undrivable. IMIA said:
Sachs feels stock but if you go for lwfw you have to get used to it as its a bit grabby with a lwfw. What clutch were you running before? Even a new OEM clutch would not hold hard third, fourth, fifth gear runs even for one pull with 673 bhp lol!
I've got the duel mass fly wheel, If I go for the Sachs would you recommend I change the fly wheel?Moosh said:

The GT3 RS 4.0 lwfw apparently has all these benefits bit is still quite civilised in terms of transmission chatter etc so you have the best of both worlds. Hope this helps.
Just been looking at reviews on the GT3RS 4.0 LWFW and some are saying that they don't last long and are prone to failures. Does anyone have experience with the above. Also I have read that the conversion creates additional rattle/noise from the transmission. Again advice very much appreciated.

best person to speak to is someone like Ken at 9e. He's done mine and it definitely rattles and transmission chatter but if you learn to be in correct gear all the time i.e. do not labour engine there is very little noise. I read the GT3 4.0 flywheel was much better in this respect but suspect its a characteristic of all lwfwSpeak to 9E or Fearnsport to see what they use on their conversions, you need something rated to deal with the torque, BHP isn't the killer for clutches.., if you track it a lot you might want a single mass, but for street use and a soft smooth pick up, a dual mass is better as they are damped.. see what Ken has to say, a stock GT2 unit might be strong enough.., or a Sachs upgrade friction/pressure plate..
I had a Sachs 890 as part of my conversion from 9e. I have (for the moment ) a lot less hp than you have, but gob loads of torque.
I believe they are using the same clutch in much higher power applications than I have. Haven't noticed any difference whatsoever compared to STD 996t clutch.

I've got Sachs 890 from 9e also with no problems, standard fw (I think), been dyno'd with similar bhp figs as op's car. Clutch feel is acceptable, biting point q high & a little hard to judge and needs revs, overall though it's not too dissimilar to oe, and it does not slip when on the power which is the main thing.

From your description sounds like you may also have a lwfw. The Sachs on its own should be no different to stock and doesn't need any more revs.Gassing Station | 911/Carrera GT | Top of Page | What's New | My Stuff
