    Hey

    From your experience what is the strongest FUCA with proper mount clearance

    Z1/ Powertrix/ Stillen /SPL /Whiteline etc.

    I like the look of the Powertrix myself as they look reasonably strong

    Thoughts?

    He's right. Use OEM and space it out. Won't quite cut it if you are stupid low, but is the best way to go for most applications.

    Sorry to highjack, I am almost looking at removing a little bit of camber from my front wheels.



    Is there a method to spacing it?
    eg. 1mm = 1degree kinda thing?

    I've never seen anything like that. Coz was selling a kit for a while that was for 0.8" drop to correct back to stock camber. That's probably a good start.

    Trigonometry baby...

    Although I believe the 300 degrees kits available from conceptz are specced for x degrees of correction.

    You could work it out, but it would be a painful messy thing unless you model it in 3d.

    Of course he is right and I agree the spacers are the way to go, the problem is that the wear pattern on Z tyres is terrible on a good day and its harder to get a proper wheel alignment with spacer only adjustment.

    So my thoughts are to get a proper alignment (good wear on tyres) I will need adjustable FUCA's rather than spacers

    Your thoughts on this?

    Cheers

    There is stuff all adjustment in the front end as it is. Pretty much toe is all you can adjust from standard. Get camber to OEM levels and you'll do fine. Plenty of times by the time you go for your second alignment with aftermarket FUCA's they are seized in postion anyway...

    The adjustment is enough to dial in the alignment to O.E.M levels without any fuss

    Based on the above this leads me to ask:
    Are the aftermarket FUCA's that bad that shims are essential ?

    If some of these aftermarket FUCA's clear the mount points then surely some of them are strong enough to do the job? The SPL are all stainless, surely they would be strong enough?

    Stainless will gall up. No lube on the threads and they will lock.

    Strong enough, sure. But the constant twisting stuffs them. And they can be noisy.

    Powertrix

    I had Powertrix FUCA on my NA (4 years) and now have the same on my TT (installed earlier this year). Never had a problem with them. I also have Powertrix adjustable tension rods (which you need if using FUCA) and Powertrix rear camber arms.

    I agree, the stock setup is best. But if you do need to make adjustments to camber in the front, I have no complaints with the Powertrix units.

    There is nothing wrong with the wear pattern on a Z32 with a proper alignment.

    Your car isn't low enough to justify adjustable FUCA's Jamie. Just space the OEM mounting bracket out and you'll be fine.

    The two issues of FUCA mounting backet and requirement of the arm to twist through suspension travel make picking after market arms tricky (and expensive and time consuming) to do right. Don't worry about it.

    id love to know who the dickhead was that signed off on using the tin sheild bearings in most of the aftermarket FUCAs instead of the more appropriate rubber seal type.

    Most of the bearing failures i have seen on aftermarket arms is because the wrong bearings have been used

    I have not been able to find Z1's Fucas on their site for a while now. Have they ceased production for some reason ?

    Hey Anti

    I agree that I am not that low, but I cannot get a proper alignment with stock.
    I have had difficulty with tyre wear patterns in the past and know that many others have as well.

    My understanding is that shimming will require multiple adjustments to get it right with an alignment each time to confirm, hence its easier to use adjustables and just dial it in.

    I also agree that its tricky choosing the right type of aftermarket FUCA's hence the question.

    I personally cannot understand myself why screw design is used in the first place. You would think that engineering could come up with a better design than a f...... screw. Most failures of FUCA's seem to be either the screw is stripped or that bearings fail.
    Using an aluminium alloy in a FUCA is of concern to me, hence why I do look like the look of the SPL's being stainless.

    I am not really concerned with stainless steel binding but more so with the threads developing play in them over a long period hence keen to hear from others in experience.

    Hence the post and others thoughts on aftermarket FUCA's.

    Cheers
    Jamie

    If you must have adjustable the UAS version 2 is the only that addresses the need for the arm to pivot. Be prepared to spend big.

    If you're having trouble with your front tyre wear it's more likely you have play in your tie rod ball joints. What is your actual front camber reading now?
