Don't buy it. **** don't work. Caused a constant slipping clutch symptom. Not to mention it actually made it harder for the trans to go in with the spacer. This was done with a fully bled TOB. Would not allow the clutch to disengage.
I bought it to remedy the tob blowing up issues with aftermarket clutches. Sadly it was a no go.
Yes I blow them up. 32 psi WOT NLS on a non lsd 4.05 Lsj trans. Yes it is still holding. Yes over 500 ponies.

 

They are too thick!!!

CED makes one a fraction of the size of ZZPs. No issues with it. It's a fraction of the price too.

 

Hope i dont have issues with mine. A little over 500 miles so far (knock on wood).

 

If you have an adjustable clutch rod I believe you'll be fine, but what happens is the spacer pushes the TOB into the pressure plate and causes slight contact and the pressure plate side won't fully engage but flywheel side will engage. Had this same exact problem as OP.

 

Good thing they are out of stock

 

A properly designed clutch shouldn't need a 1/4" of spacer behind the throw out bearing. That seems crazy. May 2-3MM at max should be fine, we are only trying to move the clutch pressure plate a little bit.

I know in this market it's not practical, nobody spends. But the right way to figure out what you need is to mock everything up and press it down and see when it releases, and compare that to what the stock TOB can do. I had to go through that mission with my OS Giken twin disc in my 350Z but thankfully there was a vendor offering specific spacer and upgraded slave kits for those cars and different clutches. The upgraded slave looked exactly like an LSJ one too...

 

I'm assuming this may work for some clutches but not for for my setup. I tried to remedy a ghost issue with mines aswell. Sometimes on very high psi pulls I can't shift into the next gear. That's when I know the tob has blown apart. It's so bad my shifter cables broke 2 times.

 

What clutch did you run? I have the southbend 4+. Zzp installed it so hopefully they know what they were doing

 

South bend stage 4. Oem flywheel.

 

so I'm the email spiral with Steve H from zzp. explaining stuff. i don't know how far its gonna get or what good it will do but I'm being entertained on his diag steps.

 

Lol. Saying what, its your fault?

 

i am being thorough, because more people than you could imagine cant figure out how to unlock their doors without help. i have to make sure all bases are covered, hence the questions.

since you are simply "being entertained" by my replies, you can find our return policy on the bottom of the website under "returns and warranty"

note, that not every car requires this spacer. the pressure plates are built very inconsistently, and if i recall, you have an "old" south bend clutch, meaning you likely have one that is too tall to begin with.

 

figured i would copy and paste the "spiral" of emails below as well...as you can see, i was simply confirming the issue, to be 100% clear that we were on the same page.

So was the clutch slipping after you installed the TOB spacer? The engagement point was REALLY high on the pedal?

No.
Yes from you guys. Way back like in 2014 I believe I bought the s4 clutch from ya.
I removed it and had no issues shifting afterwards.

I have received your review on the spacer, and wanted to email you to see if I can help, as there is clearly something else going on with your setup that is being missed.


Do you have an adjustable clutch rod on the car?

Was the SB clutch new? Did you get it from ZZP? (ours is different than the SB you can buy direct, or elsewhere)

We install these on every car we put a clutch in now, and have had exactly ZERO that have caused an issue like you describe.

Not quite saying who's fault is it. Gathering info from it I'm guessing they would want an adjustable master cyl in order for them to cover their backs. No problem at all with that. A business is a business. I seen him copy and paste the emails. I can def copy and paste them all from first to last. The end story is the spacer did not work. Unless they edit their description and put in "adjustable master cyl highly recommended" I don't see a reason to go out and purchase this and hit a brick wall. You may get lucky and jump over it without an issue.

 

Mine doesnt have an adjustable master and they did the install. I think they need to put "only works with new style southbends bought directly from zzp"

 

Probably. I'm not going to try to make it work so it's w/e to me. My car is back on the road. I'm happy with my end result. It's w/e. I'm keeping my clutch the way it is. I only put about 10k miles on it.

 

i only asked about the adjustable master to be sure that you didnt have one from a previous install, and have it adjusted all the way out. again, just making sure 100% that we were on the same page. you might view my questions as "dumb" but you would REALLY be surprised how many times i ask a dumb question, and get "oh i didnt even think about that" from the customer. i MUST ask the obvious questions. i dont know you. what seems obvious to you and i may not seem obvious to a 16 year old kid thats never changed his own oil before.....this spacer is intended to correct a low pedal issue, not just blindly install in every clutch build. its obvious you had a 'tall clutch' so this was not necessary on your build. like i said, i can take it back for a full refund.

 

I understand. I already mentioned above it did not work on my setup.
I will possibly not return it. No point with the shipping ordeal of me paying out of pocket for it. I can send you a picture of the spacer destroyed if you'd like. The value of the item is to little to worry about it.

 

Well I can say for certain he's already answered the issue I had. I ordered my clutch through a local shop and I also didn't have adjustable clutch master cylinder, hence why my pressure plate side wouldn't engage. If the southbend clutch zzp sells is different along with an adjustable clutch master cylinder being needed as well I fully understand that. Maybe it can be included in the items description that an adjustable clutch master cylinder is highly recommended and the spacer works best with only ZZPs custom southbends they sell? Just an idea that would help with marketing an item that may truly actually be helpful.

 

I'm just saying I'll stand by the biggest dealer for aftermarket parts with a good rep. They're humans too and they make mistakes and marketing a new item can be hard. I don't think we should be bashing on ZZP at all and the fact that they put effort into answering problems here will help resolve things in the end.

 

I didn't say fk zzp at all lol. I do agree on a more info on their descriptions.

 

Ok.. this is a bit of an old thread, but the only thing I found even remotely close to answering my question since it's about the removal of the Oem seal on the Tob to install onto the Tob spacer by ZZP. How the Hell do I remove this seal? Tried a socket to push it out but I don't have one the "right" size... not fat enough to fit properly or too fat and can't get it inside... I thought about hammering the "fat" one in to push it out but that'd probably be a bad idea as it'd mess up that lip and I'm pretty sure that'd fuckup the seal. What else can I do or try or what tool do I need to buy?
Thanks

 

Sorry for the ignorant post and late response, but do you need to remove the seal for this? I thought it's just something you put in first, then the TOB on top, so the TOB sits closer to the pressure plate...

 

nope. Basically that. When I took it off. There were zero signs of a leak. There was fluid splash but I didn't see it deep. I guess the lips were sealing it rather tight to make it a good seal. Who knows. This was long ago. Lol.

 

Curious to know if I would have this problem anymore switching from a stage 3 clutch to a OEM clutch?
