Adustable rear lower arms will they a require cert?

[~SlideWays~]

My JZX100 has too much camber at the back (its not too low at all) and is eating tyres. So I'd like to fit some adjustable lower arms to get it back to factory camber, or at least close.

Will something like the Hardrace items in the link below need to be certified?

They do note this:
Control Arm is made from High Density Steel
Pillowball Bearings are TEFLON COATED for Certification Purposes.

I assume that any adjustable parts need to be certified but I'm not after 'mad drift stylez' I just want to set it right. It does not have coilovers so I can't just raise the suspension.

Yeah unfortunately they have to be certed because they are adjustable.

Many factory rear lower arms are adjustable, just look under any `90 corolla.

So... I could paint them black or 'dirt colour' and they would appear factory. Really didn't plan to have to cert this one.

Hardrace items are blue so would stand out like dog's bollocks.

Yeah the JZXs do gain a lot of rear camber when lowered. What are the alignment specs? I've got a moderate drop and factory adjustment can only pull it back to -1.5 (jzx110), which combined with increased toe in seems to give me good wear based on my driving style.

You could always try a wedge shaped slip on wheel spacer?

A wedge shaped wheel spacer wouldn't work, what happens when you drive, when the wheels turns 180 degrees, it would be on a huge angle.

Not sure if serious....

Haven't had an alignment since I've owned it, need to do a couple of things before fitting new wheels/tyres and sorting camber. I had a look the other day and I only saw toe adjustment. Maybe the 110 is different/I'm blind.

The rear lower arm is adjustable on a cam bolt on jzx, it should have plenty of adjustment if you arent really low.

Yea thats a silly idea

according to LVV only load bearing arms need to be certified, however most certifiers want anything adjustable certed.

In your case you will have to

is there another lower arm from the toyota family that will fit ?? if it is an adjustable factory part, surely it won't need a cert ?

i know the rear arms on a V30 ? Camry are heavy is and adjustable, but are probably too long.

What do you class as non load bearing arms? I'm pretty sure if you removed any suspension arm the system would fail to work.

[Grrrrrrr!]

If its held on with a large high tensile bolt, then its load bearing.
Car companies dont use big expensive bolts for non load bearing parts.

Ever seen a production car suspension arm held on with anything smaller than an m10 high tensile bolt?

No? That'd be because every suspension arm is load bearing.

[92mr2paddy]

just get a wof then change the arms? if you get alignment with the new adjustable arms then keep the lenght exactly the same and if your wof guy fails it then swap arms back then back after wof, lol

then again your car should fly through a cert if you havent got any other mods that they will have a cry about. if you're planning on getting adjusties or other arms in future be good to get them all and only get one cert rather than re'certing again later.

[nz_climber]

Not sure about this type of vehicle, but if the wheel bearings are bolted to the upright then you can use tapered shims to adjust the alignment

Doesn't work where the bearing is pressed into the upright though.

Update:

The cam bolts on the lower arms have now been adjusted as much as possible and its better, but could do with 1deg less negative camber.

What did you end up with?

What did you end up with?

Adjusted via the standard cam bolts, but its not quite enough.
