My Z1 FUCA'S came unscrewed left me stranded. Was sent replacement parts and updated lock tight, less then one year later ball joint snapped, again leaving me stranded and damaged strut. Z1 REFUNDED my money, went with SPL. No issues since and no more squeeks and bumping noises either. Lesson learned, no more Z1 suspension parts. I do have their 34 row oil cooler, and rear diff cover very happy with both. Thinking of trying their rear bushing inserts next.

You realize that Z1 FUCAs are not caster adjustable, right? Like, at all.
They also break and become unlocked, as described above.

and again . . . Z1 stuff breaks. So there's that.

I'm saying your problem was half assing this to begin with, and continuing to half *** it is just gonna rack up more problems along the way

Throw on your stock **** and save up until you can do it right, or don't do it at all

or you can keep doing whatever you're doing and picking up new issues

its kinda sad you're automatically writing off "solid bushings"

Tires and coilovers have much bigger effect on ride quality then simply replacing a few arms with SPL stuff, its all in your head

Other than SPL, the only other caster adjustable FUCA is this SPC FUCA...

Ignore the MSRP.

I'm not trying to sound like a **** (but i will) . If you don't have the cash to spend on the right suspension parts, then you unquestionable bought the wrong car, or should leave it stock.

This chassis has by far the most complex suspension system out of any of the middle of the road sports cars. Not even top tier Porsche's have similarly difficult suspension system. Only reason why a Porsche setup would cost more is purely and only because of luxury taxes.

You are dealing with unequal length double A arm front pieces and 5 point multi-link in the rear (this being the bread and butter of tuning problems). Changing the static ride height at all would require significant changes on all points of contact.

You're welcome to drive around with crap alignment setup with no extra cost, but you'll have to pay to play somewhere down the line. Most likely because of premature tire wear or worn out bushings and subsequent schit handling.

Btw...you'll want to get adjustable swaybar endlinks as well. The torque values mean next to nothing if your length is not correctly set. Matter of fact, its best to have them slightly loose in comparison so that the wont snap off if you don't have the right length set for the weight balance and ride height.

Goodluck and don't kill yourself...

You have to realize that most of us here have seen aftermarket suspension parts break at one time or another. We know what works, and what don't. We are trying to steer you in the right direction. Sometimes it's a hard pill to swallow on the parts you bought are junk. I've been there myself. :shakes head: I fully understand your situation. My whole suspension is the SPL catalog. It wasn't cheap. But well worth it. The SPL upper control arms ARE adjustable for BOTH camber and caster. Install these and you and your wife will never notice any addition noise or vibrations. And the guy who is doing the alignment doesn't have to remove the tire or remove the arms to adjust them.

For your sway bar squeak. Where the rubber bushing is located on the bar. Remove the bushing, and wrap teflon pipe tape around that area. About 2 wraps. Then smear some grease over it. This will take care of your sway bar.

Can you post what your alignment specs are?

Here are threads that I put together on the SPL parts.

You are getting sound and proven advise here. I have the full SPL catalog setup myself, front and rear. You got to pay if you are play as stated above but if you do it right the car performs with the best of sports cars. As OptionZero said don't get it right and chit brakes. I had a coil over seal blow while tracking which result in additional pressure on the front end link and it snapped. Do yourself a favor...do it right and never look back.

These SPC ones, are they good?

I am soon on the verge of ordering the SPL ones from US. But SPC brand is available locally, and would probably save me over $1000. So before I go ahead with the SPL FUCA, has anyone used the newer SPC FUCA?

oh my ******* god

this is ******* ridiculous

are really asking this ****?

you have been TOLD THE ANSWER MANY, MANY TIMES BY MANY, MANY PEOPLE

sell your goddamn car man

just take uber

I told folks to stop giving this dude any new ideas

he can't ******* help himself

If they were any good at all, people would be shouting it from the mountain tops as an acceptable SPL alternative. They're not good.

But if you want to throw some more money down the drain, why don't you try them out? :ugh:

you dropped thousands of dollars into your turbo setup only to spin out the first time you mashed on the throttle and then you've been asking about wheel fitment, alignment, and stability for about two years

every goddamn time you've been told you need the SPL and a competent goddamn alignment shop, plus a dose of common sense

you wanna buy the SPC **** and report back to us how it went, go the **** ahead

pretty ******* hilarious you got no problem setting money on fire making power and slapping on wheels but when it comes down to actually improving handling and wheel fitment OH DAMN I NEED TO HOLD OUT FOR THE BEST DEAL

:wtf2:

Holy Moly dude, relax. I was only asking because I saw this thread asking similar question and never heard anything about the new SPC ones.

But really man, i think I am going to stop asking questions for your sake. Just chill bro! Lol

I have been doing thay for a while now down here in SA. So i may aswell continue, nah joking man Im gonna get the SPLs.

maybe you should stop posting anything until the SPL's arrive and you get to a good alignment shop to fix your ****

As a former DSM guy these types of threads are very familiar. Half of the posts on those boards are “why did this cheap part break” or “how can I save money on this essential component” Per the advice on this forum I just purchased and installed all SPL alignment parts and they are without a doubt very high quality items and worth the money. I feel I am doing it right and not afraid to drive the car low and have something break or bind or seize up.
