:iagree:
Same here, bolts and Loctite with instructions arived today.
Looks like they are doing the right thing.
New Product problem arises, they handle it professionally.
I will continue to do buisness with them.

That makes me feel comfortable with purchasing these FUCA's now. Keep us posted on any new developments with these arms.

The letter irritated me a bit as it pointed the blame to the owner and installer not to them insufficiently assembling the joint.

I agree that the wording made it appear that the customers and or the technicians that installed the arms were at fault.
I Emailed Spencer at Z1 with the same thoughts.
Here is his response to that statement.
with that said I feel they did the right thing.
As it is with new products sometimes there are unforeseen issues that can turn up.
It's how they deal with these problems that make them a good company or not.

I sent Spencer the invoice for updating the FUCA's...$40 @ Specialty Z

Spencer is crediting back the $40 top my credit card.

Glad to see they're working on getting these problems corrected. I was about to pull the trigger on these then all the problems popped up. Voodoo just released their from arms but at more than double the cost! I might still go with Z1 because I just need something to get me back to spec, I don't plan on tracking.

My drivers side is making clunking noise AGAIN.
Great!, I have to get in to the shop and have them look at it AGAIN!
This is getting old and inconvient as hell being my only means of transport.

Oh no, not again ?......:shakes head:

My arms started making the same noise again..... But not as bad so I just not going mess with it at this point...

Got to check it last evening and yes the bolt had backed out AGAIN.
I replaced the bolt and used copious amounts of the thread locker Z1 sent me.

Arrggh I will be contacting Z1 again to see what they say about this on going issue.

This is not something I want to have to worry about and redo over and over again.

I was so close to buying this. Glad I'm not one of the test subjects.

Hmmm, i see you guys reporting similar issues even w/ the new bolt & loctite.

To this point, mine seem to be ok still. No clunking, no squeaking, nada.

I even took her for a 'spirited' run in the twisties.

Man, this is not good.

:confused::mad:

Really anxious to hear what they had to say.

This sucks bro sorry to hear I don't daily my car, but I hit a pretty big bump the other night and the arms are still tight. I have an alignment on Wed so I'll have them double check to see if that bolt has loosened up, but right now it's still tight.

If you're married to the Z1 arms, drill a hole through the thread and use a castle nut with cotter key. You know, old school...

I had the shop use the loctite that Z1 suggested and they reused the bolt that came loose when they did the repair. I am thinking maybe the bolt was dirty from the previous thread locker. So when the bolt came loose this time I used the new bolt Z1 sent me and made sure the threads it screws into were super clean and used copious amount of the loctite. Fingers and toes crossed this fixes it for good.

Spencer has been very forthright and said if they come loose again he is more then willing to give me a full refund no problem.
Unhappy they seem to have problems, but I am satisfied on how Z1 is handling the situation.

I've got a track day this Sunday. That should be a good test:eekdance:

I'm not having a problem with my bolts coming lose... My issue is where the bushings meet the frame.. There's still that God awefull noise of them rubbing....:confused:

You could safety wire it too.

I almost bought this.

Thanks for the review

Same here! I have been following this for a while and just about ordered them and saw the issue that started happening. To bad I was hoping for a solid product..

I was thinking about them for a while as well, ended up going with SPL arms instead.

Did 4 sessions @ Streets of Willow Springs and no problems /w the Z1 fuca's

my best lap was 136.5...ok for my 1st time there.

Hey there rumblefish!! I'm the one that snagged the Blue group 1st place by 4/100's of a second haha

Good times man! You coming to autoclub next month?

I hate you:icon17:

Yeah man, that was a blast. Don't know if I'll make Fontana next month but, I'll be back out at Willow next opportunity.

Congrats on your lap time. I bet next time we'll both be down close to 130, 131:tup:

See you out there. Nice meeting you.

Any more information on the faulty Z1 FUCAs? I'm trying to decide between Z1's and SPL's. Half the price is keeping me interested but the rash of failures recently definitely and ease of adjustability on the SPL FUCA is pushing me that direction. As this would be for a DD I'm also wondering if NVH would be a negative on the SPL FUCA?

I did call Z1 and briefly talked to them but they dismissed it almost like it was a non-issue and said since then they corrected the issue or had a fix?

My first autocross session is this Sunday so I'll report back. I went and had the car aligned, no issues. I've hit pretty decent size rivets, and have not had any issues of the bolt loosening up.

I am not having any further issues with mine and have several hundred miles since replacing the bolts and using the thread locker Z1 sent me.
It seems like it was a new product learning issue.

Ran the dragon at Zdays, when I got home I checked and everything on Mine looked good!

Completed my autocross session. Everything is good and tight. No issues since install. Just FYI SPC redesigned their front control arms. They look promising.

https://www.z1motorsports.com/suspen...37-p-9584.html

They are forged steel too. Anyone running these yet?

Glad to hear the Z1's are holding up after the fix.

An updated.

I had all my issues solved through Z1. So far so good on my FUCA. Had a long road trip and everything went well. I would suggest to check the upper control arm bolt at oil changes.

Good luck everyone.

Installed these about a month ago and immediately noticed driver side creaking

http://www.the370z.com/brakes-suspen...ing-clunk.html

Z1 front adjustable camber arms
 

I don't have that noise/problem when turning the steering wheel like that, thats a popping sound consistent with a worn ball joint.

My issue is creaking noise only from driver side like others have stated. Has anyone come to a long term resolution?


UPDATE: I have come to a conclusion that after a long drive or where temperatures are high i have zero noise issues from the camber arms. This has led me to eliminate the outer ball joint being the culprit since it is all metal piece temperature wouldn't have any effect. So it is indeed the rubber bushings on the inner joints, since greasing it only fixed the issue for a few miles it couldnt be a lube issue. The rubber bushings either need to be really lubed and conditioned where they meet the metal on the body of the car, or replaced entirely.

I plan on replacing the bushings to see if this is a long term solution.

Drivers side came apart AGAIN
 

My drivers side came apart AGAIN , it happened before and they said they needed to use a stronger locktite. mine was revised with the locktite they suggested, and the bolt worked its way out again!

I called and talked to Spencer from Z1 nice enough of a guy seems to want to take care of me. I am done with these control arms not worth dying for.

I will be purchsing a different brand after the shop verifys that it is in deed the bolt that came out. All the same symptoms light clunk noise yesterday then it came apart today on the way to work, luckly as with the last time i was going rather slowly.

Update the bolt did not back out. Looks like their fix worked. It was the ball joint part that bolts to the arm? Sheared right off.
Spencer @ Z1 had been great though he is overnighting me new SPL control arms full refund for my defective Z1 arms and SPL at cost and covering all costs to have them switched out.
Disappointed about the Z1 part but they have been taking care of me 100%.

Just wanted the community to know.

That's the reason I paid a little extra for my SPL parts. People, it may seem expensive at first but worth the price and their resale value is high

Nice customer service there. Spencer has taken care of me in the past as well.

I've talked to Spencer at ZDayZ. He is a nice guy. :tup:
