Old Clutch Looks Great

Nice to see it is out of the car now.

aerosaaber Updating my thread, got the new clutch in about 900 miles ago.
First impression was how great the clutch pedal felt just sliding back and forth, I think the Tranquil sleeve really made a big difference. Initially I had a hard time driving the car because the pedal seemed to engage much sooner and quicker. When you see the pics of the old clutch you'll see why I was used to clutch engagement at the end of pedal travel.

I haven't thrashed on the clutch, and I'm at stock power levels so I doubt I'll have trouble with it slipping again.
It can be grabby at times, so it's not a clutch for your wife to daily driver (unless she doesn't mind). The engagement seems to occur over a smaller distance, the pedal effort may be slightly increased though I'm comparing it to the disaster you can see below.

On to the pics of the old clutch.

"That doesn't look all that bad, but what's with the edges being extra worn?"

I think this may have effected how the clutch engaged

The pressure plate showed a couple hot spots

Flywheel had hotspots and a weird "sorta crackled" look to it

Amazingly, this car was TOTALLY drivable, only WOT would really cause any slippage. I actually drove this car almost a month (probably almost 3000 miles) before getting the clutch put in. The only other clutch I've seen in this bad of shape was on our Rally car after it was slipping enough in deep sand to actually get the fibers hot enough to disintegrate and set the plastic clutch cover on fire.
In the end, that clutch had absolutely no friction material on either side.

aerosaaber Got some pics of my clutch and flywheel, still all wrapped up. Installation going on tomorrow.

aerosaaber the tranquil sleeve cost me something like $150 including shipping cost. I found it from iirc.

I chose the Spec clutch because I have friends who have had good experiences with their products. The exedy also didn't list any specs regarding how much torque it would hold, the spec is rated for 300 lb.ft.

humboldtsubby Hey,
Q1:How much did you pick up that tranquil sleeve for and how is the install?
Q2: What made you choose the SPEC clutch over the Exedy?

aerosaaber Ordered some parts:
Tranquil snout sleeve
ACT streetlite flywheel (like 12 pounds)
SPEC stage 1 organic (rated to hold 302lbft) - I wanted a full disc organic, I've had a 6 puck kevlar in another car and hated it.

I figure the hydraulic stuff can wait since it's outside the bellhousing. On my Saab the slave cylinder was inside which if you ask me is a dumbass way to do it.

Clutch Action

We moved him about a foot and decided not to smoke our new clutch! He was bottomed out on his center section! Now how would he have known ahead of time not to drive himself into the predicament.

aerosaaber I found "F1 racing" clutches online as well, the reviews I've read on some sites are favorable and the price is much better. Anyone have experience with these?

How light should a daily drivers flywheel be? I'm seen Fidanza's Al flywheel coming in at like 8-9 pounds which seems "too light" for a street car.

aerosaaber The clutch is only really slipping at WOT at those rpm's. At less than WOT is seems to hold just fine. I'm not really trying to "put it off" just get the parts I want beforehand. I've had trouble in the past when something broke and I didn't have the time to do the research or get the upgrades I really wanted. (When the stock turbo on my Saab blew and I had to have it running that weekend for a long trip comes to mind).
