Clutch questions

Patporscheguy · 03-17-2003, 04:42 PM

I am putting my engine together and I noticed that I have a rubber center clutch. According to my mechanic it has a good amount of life left in it, but there appears to be a crack in the rubber. This may just be they way it was made but it is a good excuse to put a new clutch it in case my youthful exuberence destroys this one

.

My question is what clutches to you guys reccomend for a fairly low price? Is the Sachs kit the best for $? Also what about lightening the flywheel while I am getting it resurfaced? Will this destroy the integrity of the metal, or be unstreetable?

Thanks for helping a nube out!

I would recommend the sachs clutch. I would not bother with the flywheel for street use. It makes the car harder to take off in first gear without stalling and if its done improperly you could get some bad vibrations. From experiance with a turbo 944 I learned that the rubber center clutches are junk. I would imagine the 911 is the same story. Why not just buy a sprung disk if your pressure plate is good ?

Agree w/ the Sachs or Sport Sachs. Rubber centers are a disaster waiting to happen.

Ok thanks guys, I'm gonna get a pro to look at my pressure plate to see if I need a new one.

Does anybody know a good machine shop in San Diego?

Thanks,

Check with Black Forest in Kearny Mesa, they may be able to direct you somewhere.

Pat, just buy the whole kit. You'd be pretty crushed to go through the trouble of installing a new disc, only to learn later that you need a new t/o bearing too. The whole kit come with everything you need and it's not that expensive. When you have your engine out, it's no time to cut corners.

I have a Sachs aluminum clutch with a Truman aluminum flywheel in a modified n '83 SC street/track car, and it's no harder to move from a standing start than is my wife's Boxster. Maybe easier, in fact.

Is there a Porsche Part # for a spring centered clutch that would work in an early (1974) 915? Switching from a rubber center and I figured the stock part would be another rubber center.

Thanks,
