What is the "Clutch of the day"
So what is the "clutch of the day"
The Textralia was the the hip clutch that everyone was goin to last year or so... Then the C6 Z06 clutch was the bomb...now I was told the Spec 2+ is the bomb diggidy.
What is the latest and greatest?
I need one before the "FEST"
My Z is basically stock...I may throw a cam in too while I am at it.
What I need it to handle maybe is 450rwhp for now.
I do not baby my cars so I beat it like it owes me money!!!
It has to take abuse!
Actually the stock clutch has taken alot of abuse and I have not had any problems with it...till now grabbing high and sticking in hard shifts. It is time.

If I have to choose again, it would be a toss-up between the Tex 0Z700 I currently have or the Centerforce that Ed is running,,,,and considering that the Centerforce is half the price of the Tex, I think that would be my choice!

If i were you stay away from any of the Dual Disc Clutches.. Not much give and they are hard to slip..

That is completely untrue. I have a Mcleod dual disc in my car and after the correct break in it drives very stock like. The pedal is alot harder than stock but it doesn't chatter and will slip more than enough for easy street duty.

I have an RPS Stage 3 Dual Friction and it feels like I am pressing a old 2 and 1/2 Ton Military Truck clutch. Funny because Jason at Extreme in Phoenix stalled my car 6 times backing it up. Its hard to handle for those not used to it. But I am used to it, and I like its stubborness......It feels good to me, but very stiff.

I have 20K miles and prolly 50 or more 5000 RPM launches on my Tex Ozz700 clutch and it still feels just like it did the day it was installed. It takes a lot of abuse, trust me, I drive my Z. It's hard to push the pedal down. (didn't realize this until I bought a Camaro with a C5 Z06 Clutch and almost put my foot through the floor the first time I pushed the clutch in it was so easy) The Tex clutch chatters a little if I slip it too much, but this clutch clamps really well while still allowing a little slip, and I've never had the pedal go soft. I have a bleeder and bleed it regularly and install fresh fluid and I'm sure that helps a lot. I will buy another Tex when this one expires.

I have the Tex dual and it has been great. Keep in mind that what ever clutch you use make sure the stack up measurements are correct. You can have major clearance problems on aftermarket clutches that will make the slave/release bearing to push on the fingers and prematurely wear out the clutch plates. I have used alot of clutches and found out the hard way.
I'm still liking the Textralia 0Z 700 clutch on my ride...it's smooth (no chatter) and the pedal effort is very close to the stock feel. I've had no issues and no regrets with this clutch.

What exactly do you mean by "stack up measurements" ? I'm changing my PP flywheel and slave soon with an Exedy setup, and plan on adapting a C6ZO6 slave/master if possible.

From the beginning my centerforce clutch felt like the original clutch when it comes to effort. Since you have to take out 3/4 of the drive train to get to the clutch it is advisable to replace the flywheel while you are there. I put in a Fidanza aluminum flywheel. The engine revs quicker and more of the available horsepower goes to the wheels instead of it going to accelerating the driveline. You are litterally reducing the percentage of driveline loss between the crank and the rear wheels. Horsepower is expensive on our cars so don't overlook the utility of making this flywheel change also.
It has one feature unique to Centerforce and that is the sliding weights. They increase the plate pressure the faster you spin the clutch which is just what you want.

The Exedy Twin was the one that I found the issue on. I had a Exedy single that lasted 4k miles and then a Exedy Twin that lasted about 6k miles. They all failed the same way. The discs just wore out. Exedy told me that the Exedy Twin was NOT designed for normal driving (right after the single failed and they sold me the Dual AND said that is what I should have used) and told me that the dual is for strip use only and that is why it failed so they gave me a single for warranty, which I sold
I started to look at the Tex dual plate and with help from one of their head guys there, I started checking the "stack up measurements" WHICH MEANS
When you have a hydraulic release brg inside a bellhousing after you install all you internal parts of the clutch system there needs to be a .060 gap between the release bearing and the fingers of the pressure plate (with no fluid in system and pushing the release brg back) if not you will prematurely wear out the discs. All this can change when you install aftermarket flywheels, release brgs, pressure plates AND differant stroker cranks and versions of the LSX blocks. On the Exedy Dual with my LS2 stroker build up I ended up with the release bearing pushing IN on the fingers about .110.
That is why the first and second Exedy clutches wore out. They came with a flywheel, I don't know if that was the only problem because it had a aftermarket stroker crank and I used a LS2 block instead of a LS6 block in my 2002 ZO6. With the Tex Dual I ended up machining about .080 OFF the pressure posts which pulled the fingers in about .125 to give me the .060 gap I needed. This was all done with the help over the phone from the main brain at Tex clutches. On the triple plate clutches they machine the release brg housing so they get that clearance. Alot of people aren't even checking this measurement and after I learned about it, I have seen alot of issues.

Thanks for the explanation. I will be using the single disc setup Exedy, and a stock LS6 block. I was going to buy a Tex, and was ordering from LGM, and they talked me into getting the Ex. It cost alot more, but they insisted it was a better clutch for my application. Since then, the Centerforce has been used more, and is much cheaper than either Tex, or Ex, so I'd probably go with it now. I hope I don't have your premature wear problem with the Ex, since it cost so friggin' much.

I've heard good things about this clutch form a guy who has a supercharged Z putting around 600 RWHP down. I know he runs his car hard too...he's a local street racer and I talked with him about his clutch for a good 30 min at a local meet. He said he loves this clutch and wouldn't ever consider another. I only wish there was a way to test each clutch on your own before buying one....I'm in the same boat trying to decide what clutch I want...
