These guys are right. You're getting screwed.

$3000 =

$1,500 for a complete South Bend Stage 2 daily kit from Zspeed. Tack on labor around $6-700 you should be out just barely over $2K!

I'm also a victim of clutch failure. In my case it was the CMC that began to leak. Pedal is to the floor, and no hope of driving it to repair. I've decided to also go ahead and have the CSC replaced too. I'm awaiting a quote from AAM Competition, and if it doesn't hurt my wallet too much I may go ahead a upgrade to a new ACT Clutch kit as well.

I did the exact same thing as you - my CMC failed first and I went ahead and put in the Z1 kit at the same time. You are getting an aftermarket CSC solution, right? It's definitely a good idea to replace the CSC because the failed CMC can let dirt into the system and will eventually foul up the CSC (a failed CSC can foul up the CMC as well). But there's no way I bother dropping the transmission just to put another OEM CSC in there.

Yes I'm definitely going for a HD Aftermarket CSC too. I'm anxiously waiting to hear back from AAM Competition. I've always had great service from them & they are very helpful.
I'm not sure if CMC had failed before with previous owner. But I do have documentation that original owner replaced CSC when car had 52363 miles. Currently car has roughly 64,000 miles. It's going to be gut wrenching to see my Z get taken away for repairs by a Rollback Tow Truck!

How many miles do you have on the car?

Thinking back maybe it was either the hot Florida Temp. Or the dirty fluid getting flushed out did the trick in my case. There was never any fluid leak visible. The stock setup is close to all kind of hot stuff and the pumping action of the clutch makes all kind of internal crap that you can see in the fluid. I still periodically stick the tube of a windex sprayer down the clutch fluid fill and pump out the dirty fluid into a cup and put some new in. When it was acting up it acted the same as the clutch failure, dropped to the floorboard or went half way down. That's why I think some here might be helped with the service bulletin flush and refill cause they might be boiling over or have contaminated fluid vs an actual failure.

Just got my car back, a day earlier than expected. All seems well, and the out-the-door total didn't increase (*whew*).

I did, however, fail to anticipate that new clutch = new clutch point. I felt like a newbie stick driver all the way to the office just now.

MAN did I miss my Z!!

2009 Sport/Touring
VIN: #2001
Purchase Date: 02/24/15
Occurrence Date: 6/6/15
Occurrence Mileage: 31075
Clutch Type: OEM

Summary:
- Around 04/15, After work I stopped at red light that was at a decent incline that goes over the freeway, I got going and the clutch pedal didn't pop back up immediately. It just revved until it grabbed... I got to my destination which was about a mile away and left it for a few hours. Drove fine after...
-06/06/15 Drove 60 miles to go on a date... Picked up my date and got about 2 miles down and noticed the clutch pedal wasn't coming back up more than an inch... It was just enough to get it to go but it stalled several times before that. 1st and 2nd gear wasn't easy to get in to... Got it to a parking lot and called "AAA" waited 2.5 hours and the date was ruined. As we pushed it back to get it on the tow truck I noticed oil on the ground.

Conclusion:
6/14 Confirmed the clutch slave cylinder is the cause, Carmax's warranty approved of the repair to the tune of $760 using OEM parts.

6/17 Complaint filed on the NHTSA website where several other complaints from people explain the same issue along with the common steering lock failure.

Oh man that's terrible. I feel your pain. I recently had same problem. My Z is still out of service. After reading many others post on the forum I decided to go with HD CSC. I'm not going to keep spending money & drive in fear of being stranded with another OEM CSC. I took the advice of others and ordered a HD CSC from Z Speed Performance. I haven't read of anyone having problems with it. I'm also replacing the CMC & adding the Insulated Short Stainless Clutch Hose. You should check Z Speed and get your order in quick for HD CSC as they go fast. Contact Joe at Z Speed.

Updated... Confirmed it was the clutch slave cylinder.

Sorry it depresses you. "Tip For The Day"- check your clutch fluid level at least every other Fill-up. If it gets low it could be symptoms of CSC Failure. Don't get stranded like so many of us have & required to be towed!
