AMS Front Camber Adjustable Arms
 

What do you guys think? The pics are blank on my IPhone but if you click on them it shows the pic after.

Those look very similar to the Kinetix Front Camber arms that everyone dislikes.

AMS..I'm just going to keep my mouth shut. ;)

Not much negative camber there

those are rebranded kinetix arms... very poor design in my eyes.

Yeah I've got the Kinetix (hey, they were practically free) and I can attest to them being very low quality.

That said, they can't slip and lose your settings....

Does anyone not copy others?

True enough for the most part.

Still, you could get the Kinetix (same design) for a lot cheaper I think?

I guess I'm going to call SPL and harrass them some more.

So who has the best right now? I will need some in the near future so I can adjust to zero camber when daily driving and -5 when daily drifting. Looking for some that will allow me to do so which i can save the settings and switch back and forth.

If u dont need to adjust ur camber, why not just do 1 tac weld on the spc ... so then its not going anywhere...

Why do you find the Kinetix very low quality?

Both boots have torn off on mine, the hardware is as cheap as possible.

They're heavy, they're ugly (reaching?)

They're just cheap, functional parts.

If you can set it and forget it, and get them to be in the range you want (I'm at maximum negative with them and my swift springs, -2.6 deg) then they're fine. Otherwise, I'd look elsewhere.

Do you want more negative than -2.6? Are you going by tire wear or temps?
That isn't an extra -1.5 degree over stock is it?
I'm not going to adjust my camber once I feel it is good compromise between street and track. I have -1.6 with coilovers lowered about .75" or so and I am wearing the outside on the track. I have not taken temps yet though. One option I am considering is just getting offset bushings on the OEM upper control arms.

Wish I had my stock arms, I'd consider that as well.

I don't personally want or need more than -2.6, someone might tho?

And I based it originally off of just aggregating info on this site, but confirmed with temps. The front is pretty close to perfect, at least with the weight it was last time I put it on the track (lost a lot since then).

It'll all change when I buy coilovers in a couple of months, anyway.

Called SPL again. Same story. ''Give it a few months, very early next year''. He continued to say they had to do several revised sets to get them right for clearence issue for the retail market. He also claims there at the machine shop and it's hard to force them to do work. And that they had several out on some race cars even though not 100% perfect it was good enough for them.

I stated to him there's a big demand for them here and he was aware. They want them out. Sooooooo......... I have SPL everything else so I really want there front arms. My SPC are great though as long as the top nut is TQ to 150lbs. It has never slipped once but the top nut has started to strip.

The only ones that would be easy to switch back and forth IMO are the Doran arms which unfortunately aren't commercially available.

With all the copying going on out there, I'm really surprised someone hasn't reverse engineered the Doran arms from the pictures they have posted.

Cool thanks for the response!

I just realized SPL is right across from Uprev in Austin TX. When I was getting my tune I seen their building, but never even thought twice about it. I should pay them a visit and see if I could take a look at these arms they claim will be ready next year.

in the past, the spl's UCAs were known for that property/ability

"Edit"You post months ago that you like the look of their design,

Did you have version one or version two?

What are you talking about... I have been on SPC since the car came out... Kinetix is a brand I have not like for years... maybe your confusing me with someone else or my posts for spc brand and spl brand...

I am trying to post it you,said you don't like the way they look,
Everybody jumping on the bash Kinetix cambers arms do you guys know there was a version one and a version two which the two is out now so we will have to see if they are any better.

Here's a picture of the SPL front arms on the SFR Enterprises WC 370z. No shims in sight. Maybe they changed the design since then but I highly doubt it.

They make great stuff but the problem has always been cost
Doran arm? $1500
SPL arms? $800

I'm guessing on price but I'm probably not far off.

SPL will be good bit cheaper. $600 maybe.

Racing parts are expensive.. Don't want to race, get SPC or Kinetix, they're good enough.

$500-700 is where I'd expect the SPL arms to come in at. They look like cast aluminum versus machined billet like the Doran arms.

That looks like a lot of adjusting and with the possibility of on uneven lengths since you have to adjust both ends.

You could adjust caster that way I would think?

I was wondering the same.

I doubt you could adjust caster with those as they just slide in or out on the rod :)

If you slide the forward most rod outwards without moving the rearward one, you effectively move the top of the suspension rearwards, adding caster.

It would have its limits of course, but it could be used for fine tuning...

It doesn't look like you can move one without the other, that would bend the rods they are on.

The rods have to stay parallel and the bushings shouldn't allow for fore and aft movement.

With these. You can adjust both camber and caster.

how can you adjust caster??

Easy, all you have to do is to move one side of the arm. By the looks of that design. you should be able to move it about -or+ 2degs.

How can you move one side without moving the other if the rods are parallel?

The heim joints will allow for the difference.

If those are heim joints then
A. the whole control arm can move fore and aft
B. It still would not allow you to move one side without moving the other as the rods are still parallel and the assumtion is no bending.
