Roll Center Adjusters ? (Collar vs. Shank)

Noooo but it's Tein! They're billybttadassBALLER parts d00d!! That's gotta be the right way!

I like in the tein install they are pressing on the center instead of the outside ring during install, surefire way to kill new balljoints as that collapses and contacts ball inside saving grace here being that in theory the ball is now moved up significantly,

That whole design is short bus special

Thanks

I found it a bit difficult to visualize, but after plotting it out on some paper I see there will be zero (or virtually zero) camber gain under cornering.

[Matt93SE]

true. the differences will be so minor, they won't be too noticeable. you will have to realign the car though as it'll cause a small amount of toe out when you make the change.
all in all, it's a negligible difference tho that can be adjusted out with adjusting the tie rod ends.

[Def]

the only reason it changes the camber/toe curves is because you're lengthening the arm by a tiny fraction.
Assume the stock arm is 12" long and the spacer thingy is 2" long.
adding the spacer before the pivot just makes the arm 12.16" long now.

It gives more static camber if that's what you're after, but no change in camber gain (which is what my earlier post was talking about).

Just clearing things up for the guy. We're saying the same thing, just talking about different aspects.

[Def]

Moving the arm down without moving the pivot would still change the camber curve, won't it?

Or is the difference negligible/not worth the effort?

NO difference whatsoever. The physical arm appearance doesn't matter, it's only the imaginary line between the two pivots.

You want to move the PIVOT location down in relation to the ball joint mounting location. So you want a longer shank length. Just moving the whole housing up and down does absolutely NOTHING to suspension geometry.

Shut up and drive!

Very nice!

Maybe this will help:

What Josh said.. Just cause they don't do anything doesn't mean stupid people won't buy them.

Electric system "Power stabilizers" ??? Ever opened one? most of them are a chunk of battery cable wound a couple times into a coil and then potted into a urethane brick so you can't see it's just a freakin wire in a box. And people pay $300 for these things!

just because it doesnt work doesnt mean people wont buy it. im sure someone at tein knows better, but what do they care

Tein made this. Megan must have just simply copied them. I'm suprised Tein dosn't have any one that understands the kinematics of body rolling.

The point is they are makin lots of money selling overpriced crap that doesn't work. They probably don't even know why it would or wouldn't work.

Why else would a knock off company sell stuff?
