XTD Clutch scam!

[Supracentral]

I believe you...but that's unbelievable!

On the bright side...I guess slippage under acceleration wouldn't be a concern anymore.

Can't help but wonder if the major factor here is:

a. strong pressure plate

b. weak crank

c. all of the above

It's the #1 cause of failure of MKIV turbo motors with manual transmissions. Most of us have our clutch safety switch bypassed so we can start the car without pushing in the clutch. Really helps keep the wear off the cranks thrust washers.

From looking at the Sout Bend piece again, it appears exactly like the XTD unit on the first page, even has the green dot intact on the diaphragm (appears to be a faded dot and then a newly painted one.

The tabs on the side are still painted green like the stock unit and the rivets have been drilled on the back (balancing?) I'll compare to the stock piece once I remove it and post some pics.

How interesting....I bought one of these to put on my honda a few years back. Those damn bastards!! :madfawk:

The proper way to see if in fact they are misleading people is to test that pressure plate on a press and see what the clamp load is.

Big clutch manufactures like ACT use bone stock pressure plates and modify them by heat treating. This adds a higher clamp load which offers you a higher torque capacity. You can not go by looks alone.

But yes i will have to admit i have herd some bad things about XTD. Something along the lines of its a 2 man operation out of a home garage lol.

Well, I bought one of these scams. I figured that the PP would be stock, and hoped that the 6 puck sprung disc would work out for me.

I will probably still put it on the car, until such time as I can get the ACT clutch setup that I really wanted.

Edit:

Though this is the "F1" clutch that is supposedly a rebrand action clutch, from info that I've gathered in this thread...

1. There's no split or groove in the middle of the pucks.

2. The friction material is a darker colour.

3. The clutch PP was obviously not disassembled before painting. (You can even see blue overspray on the tines in the "TOYOTA" picture, not to mention the side spring pic.)

At least the pp, throwout and pilot bearings appear to be OEM Toyota/Aisin parts, and the pp doesn't look like just an old pp that's been machined, it at least looks like either new, or properly remanufactured.

I've had the XTD clutch in my car (87 n/a) for a little over 6 months now. No problems. Broke it in easy for the first 500 miles or so, then went back to my normal, "launch off every light" driving. Race quite often, dump the clutch at 2500 to 3000 rpms for the hole shot, and grabs good still.

Still noisy, though...

^^^Wait till you have more hp/tq. The tranny doesn't like the clutch at all.

I got a F1 Stage 3 for my SC300 5speed and my buddy has a 1jz with a r154 and he got their 1jz light weight chromoly flywheel and F1 Stage 3 clutch. Both clutches we inspected throughly.

- They definitely are NEW components nothing was "remanufactured". They use quality new components from companies like Exedy, Luk, Valeo, Asin, etc. Depending on the torque rating the pressure plates are modified stock pressure plates to allow higher clamp load. (ACT also does this.)

- As for the groove or split in the 6puc disc i wasn't so concerned about, it probably would add a minimal amount of cooling.

- I asked them about action clutch recently and they said they are not affiliated or buy from that company. He did say their parts are Chinese and not good quality.

- The friction material color doesn't really mean anything as far as i know. As for painting or powder coating. A lot of companies ie. Centerforce, ACT paint their pressure plates this is not really that important but it does prevent rust.

So over all I'm pleased with The F1 Racing products and would recommend them and purchase from gripforce.com in the future.

That the pressure plate is new, I don't dispute. That it's been upgraded, I guess there's no way to tell, but I strongly suspect that it has not been.

The disc doesn't look bad, I don't think that there will be a problem with the friction material coming off or anything. But I don't know that it'll be significantly better than any other, and as mentioned, a 6 puck disc on a stock pressure plate can cause other problems.

That being said, I'll give it a try.

I could probably get by on a stock clutch, and so it'll probably be fine. It all depends on what I do with my turbocharger.

As for painting or powder coating. A lot of companies ie. Centerforce, ACT paint their pressure plates this is not really that important but it does prevent rust.

The concern with the paint is the overspray which implies the PP was never disassembled, and never strengthened.

What I bolded is because they where CAUGHT in their scam. They are NOT modified!

Read the thread and purchase from trusted vendors, not scam artists (keep in mind you can buy the SAME pressure plate as them for very little, and then buy a good 6 puck clutch disk and still come out cheaper, you're being scammed!)

What you are saying doesn't make any sense. Who got caught? XTD got caught?

I trust Gripforce just look at their feedback on ebay gripforce-clutches( 31935 sells and 100% feedback). But I definitely don't trust XTD their id on ebay is aimcoclutch( 18152 sells and 99.9%).

Just took another look at a gripforce "f1" clutch for the Supra.

Sure looks like exactly what they sold me, but there are some differences in the ad, now.

I could swear that it boasted a 40% increase in clamping power before. It now says 20%.

There's also a lot of info there on how they harden the diaphram and replace the drive straps. It also talks about "CNC machined castings" -- which is true, but misleading. The castings are obviously stock, and Toyota/Aisin does use CNC machines on the castings.

Not that I object to a stock casting for the pressure plate, in fact I'm happy to see that, because it means that I know that it'll fit correctly.

However, their claim of stronger drive straps and rivets doesn't appear to hold a lot of water, considering that the ones on my unit appear to be exactly identical to the stock ones.

As for eBay feedback, I don't know that's all that reliable. I ordered a clutch, it arrived, and on initial inspection appears to be the correct one for my car. I left positive feedback. I haven't yet installed it in my car, I don't know what it's capabilities are, and I've already left my feedback, so... As such, what that feedback tells me is that they actually ship product that fits the car that they sell it for. Nothing more.

I'll trust them IF I get a reasonable service life out of my clutch after it's installed. Until then, I'm expecting that what I've got is a stock pressure plate, and a 6 puck clutch disc. (And maybe this is reasonable for what I need after all.)

I could swear that it boasted a 40% increase in clamping power before. It now says 20%.

If you add a four or six puck clutch to a stock pressure plate, the TQ holding capacity usually rise 20-25%, so I dont know they are implying that or the actual clamping force of the pressure plate.

 

[starscream5000]

I'd say it's the first .

Ebay feedback is very misleading. If only I could have changed some feedback on a few things I've bought on there before, people would get a better idea of the credibility of some sellers, not just their ability to ship an item out fast. :nono:

 

[Dan_Gyoba]

They are specifically claiming that the pressure plate has a (now) 20% increase in clamping force. Specifically clamping force. Torque capacity is something entirely different.

(I'm also sure that it used to say 40% increase.)

fucking bitches

SUE!!! lol

Don't seem to be that horrible that some of you writes, read in a swedish car magazine about an english Supra MkIII that has potential for 10s on the 1/4 and it uses a XTD clutch disc.

I used it also on my old 400rwhp Supra, was very happy with it.

the problem isnt the power handleing, its the fact that they lie about upgrading the pressure plate.

and Im still interested in specs rating.

aaron you have a spec pressure plate?

 

[ModularTurbo]

Hey what about the F1 or er FormulaONE clutches that are going around do you guys think its a scam too. I bought a stage 3 6 puck I hope it holds I haven't put it in yet.
