Well I didn't really like the shutter on soft take offs... Seems like I never gave it enough gas... The ZR-1 is great in this category...

I really feel like I made a bad call on this clutch now... I do take mine to the track( Haven't yet since new clutch ) But the last time I was there there, I felt the clutch slipping to the 60' mark... I had a terriable run... I ran a 14.13

After that.. I called it a day and went home.. The next morning is when I noticed the oil leak.. So when I took it into the dealership to get it fixed... It wasnt to hard for the tech to talk me into getting a new clutch...

My suggestion would be stay away from the organic disks. With the right clutch assembly your peddle will never drop or stick to the floor. I too think the spring mod is a band aid.

In the last 10 years I've tested a ton of clutches for drivability and life.Have blown up 7 of them personally in my own vehicles. Right now my favorite are Monster and Mcleod RXT's.With both of those the peddle will never stick on the floor.

The ZR1 clutches? I'd say they work for alot of people. We haven't had luck with them at all but our cars are driven hard. My dyno also showed them slipping in the whole rpm area when cool then they started to grab better the hotter they got but the peddles would stick to the floor. Must be the load dyno bringing them out because when I take out the 4000lb car load and use a generic 2k lb load they show no sign of slipping.

Have you ever tested the SPEC (1500lbtq.) Twin or the RAM RTrack (1300lbtq.)?

Not sure whether it makes that much of a difference, but those who have added a separate clutch fluid reservoir find that it has solved the problem IDK. There are a number of theories on why this happens, some say it is fluid temperature, some blamed it on the stock pressure plate but I don't think anyone has actually found the real cause. If it is none of these, that only leaves the master clutch cylinder. The last I heard, there is no replacement or upgrade for the master cylinder.

This problem has been around for a while. I read an article of an improved master cylinder that reportedly helped the clutch sticking issue a few years back for the LS cars. I couldn't find the article, but here is another I found on GM HighTech Performance site:http://www.gmhightechperformance.com...ics/index.html

What amazes me is GM continues to pretend they don't know what's causing the issue. Amazing isn't it?

I've tested 2 of the Specs twins,PT series.They were both pre production as test unit's. They were both great clutches and abused to hell and back on 900rwhp cars.They both lasted over 50k miles. Very good clutches. Since the testers they changed the disk material alittle bit and made the newer clutches chatter a bit on take off. Mine had and still have no chatter.

I've seen enough older RAMs not last long to even give them a try.

The GTO's are very well known for the crap rubber line expanding while pushing the clutch peddle.

That article mentions hard to get into gears which leads me to believe they installed a LS7 clutch which is not designed for that hydrolic system.It will not disengage enough. So,they band aided it with a bigger master cylinder.

My 2001 TA was a M6 and made over 200 1/4 mile passes with it. The peddle stuck to the floor with the stock clutch.With the better non-organic clutches my peddle never stuck to the floor and had no problems shifting gears at 6900rpm. Made atleast 120 passes like that.Same clutch fluid was in there the whole time.

master clutch cylinder is the problem, along with the whole stock hydraulic system. contact member JUDE on here. he had a 1000rwhp clutch problem and Fastlane replaced it all but i dont remember what they used

OK, so I just called Lingenfelter today.... I wanted to see what they would say is the cause of the problem...and to see if they would help me with a fix.... Well all he said ( Tim ) was to bleed the clutch... ( told him that its been done twice ) and if that doesnt fix the problem.. That they sell a return spring kit for the pedal.. So once again.. No serious fix... Just a band-aid for the problem.. I asked if I could get a discount since I'VE NEVER HAD THIS PROBLEM BEFORE. Of course I was told no... Its 89.95....

I really think that's Fu**ed UP.. I spent 1873.00 on a clutch..... now I get this problem.. then they want to charge you more money for a band-aid cause their clutch isnt worth a Crap!!!

To anyone who is thinking of buying the ZR-1 clutch.. DON'T!!!!!!!!!!!! IT STICK TO THE FLOOR....With no help from LPE... except spend more money...For a sh*tty band-aid fix!!!

Im taking this clutch out of my car!! It's NO good to me!!!

WTF kind of crap is this!!! So mad I could spit bullets!!

[calbert1999]

Do like Ophrah (Wow, .... wow.....). I"m amazed this issue can continue for as long as it has without any resolution.
Sounds, like regardless of which clutch you purchase (1-2k out of pocket), this issue won't go away.
Hellooooo........ GM, Chevy, anyone that works at that company, anything to say??????

Bro' I'd be pissed too. But, I don't think the issue is the clutch, I believe "depending" on clutch materials (organic or steel) you may or may not have the issue(s), depending on how someone drives their vehicle.
In my opinion the real problem may have to do with the hydraulics of the entire system (master / slave cylinder), and / or combination of other things (the shifter mechanisms, syncronizers, single fluid system between brakes / clutch, small master cylinder, cheap rubber tubing instead of larger guage nylon or stainless tubes, etc...) that further complicate shifting (grinding gears, shifter get's stuck at higher RPM's, pedal stuck to floor, etc.....).
From what I read, I think most people change their clutch to resolve a number of issues, "and" the only workaround for now with the pedal is the dumb spring fix from LPE.
LPE is probably the only ones that come up with a quick fix for the problem.
Personally, I believe anyone with clutch issues need to complain to GM (head office not dealerships), perhaps if they get enough complaints they'll do something about it.
I would bet the clutch issues are very prevalent in 2010, 2011, and will be in the 2012 (all version including ZL1), and if not in future versions GM needs to pony up and tell consumers how to resolve the issue or make a recall to fix the issue.
It could be very "dangerous" driving on the freeway, and your clutch sticks to the ground and you're no longer able to shift.
This happened to me once already on the freeway, I was very concerned.
If the problem is someplace else in the system simply changing the clutch won't fix it, we either have to change the whole system or live with driving our "sport cars" like granny does.

I believe for most people this is only happening on the track, or during "spirited" street driving, not while shifting to 6th at 65 mph on the highway.

I understand the frustration, but if I was having the issue I would certainly try the $100 band-aid, versus ripping the whole thing out. I believe every brand of clutch has had the same problem.

The part I don't get is.... I never had a problem with my clutch sticking before.. It started this right after changing over to the zr-1.. which makes me want to blame my issues due to the zr-1 clutch..

and the fact that I paid 1873.00 to now have this problem.. thats what really pisses me of... and lingenfelter.... LMAO wants basically 100 more dollars...

There is no way I can live with this problem.... When all come down to it.. that... this is the way it is... sorry about your luck.... Im selling my car..
