hey all,

My adjustable control link is telling the story that I am getting flex in the attachment point. This means that the trailing arm is is able to flex and I have to compensate with more negative camber.

What is a suggestion in making the subframe stiffer at the control link location?

Thanks,
Ben

 

Do you have solid subframe bushings yet? By adjustable control link do you mean the individual camber adjuster?

 

AWR has the full shebang of all those adjustable pieces and with the solid bushings, the subframe should be planted

 

I have MMR's bushings.

Yes I mean individual camber adjusters.

To clarify, I am focused on the camber adjuster's attachment point to the subframe. This is the part that is flexing.

I agree with you on this and have all I can have here BUT the attachment point is still a potential flex issue, as seen by the wear of my camber adjusters.

 

do you have the main link in conjunction with the individual adjusters? I was told that that without each other both components will wear prematurely.

 

Do you mean an adjustable sub-link or as Mazdatrix calls it: "rear camber adjuster"?

Yes I have this also.

Are we talking about methods to reduce the connecting point flex yet?

 

flip the rear diff collars upside down = poor mans stiffer rear diff mounts.

 

Guy, although good thoughs being bantered, this is not the focus.

Subframe - to - trailing arm... This is the area being discussed and stiffening it up to reduce flex and reduce the inherent camber produced because of the flex.

 

Untill they collapse and let the diff move around again.

 

You got lied to. You do not need the sublink adjuster if you have the individual camber adjusters. Nothing will wear out prematurely.

 

What camber adjusters do you use? I'm assuming you use AWR/Mazdatrix adjusters since those are the ones that seem to wear out. Switch to the MMR adjusters that use a heim joint, and they won't wear out.

The camber link mount is not really an extremely high load area, and I doubt the mount on the subframe is actually flexing. Remember that the OE camber dogbones can pivot. The AWR/Mazdatrix units can't pivot. They can bind which causes them to wear out. Again, the MMR design seems to address this problem better.

Are you running some kind of spherical bearing (AWR or MMR) in the rear control arm or just the stock bushing?

I have coilovers, RB rear sway bar, solid diff bushings and subframe mounts, MMR individual camber adjusters and MMR spherical rear arm bearings and am not seeing any evidence of flex or camber change out back. I run -1.3 degrees of camber in the rear.

 

I've seen a few pics of the individual adjuster shearing due to not running the adjustable link. I think it puts a lot of stress on the individual ones.

But anyways what you're running sounds pretty solid. I'll let you handle the topic haha, my rear end is shot most definitely.

 

They shear if you hit stuff and/or dont keep them lubed. The AWR/Mazdatrix ones can bind, and wear out for the reasons I posted above... because they dont pivot. The MMR units pivot, and won't bind up.

You cant even use an adajustable sublink with solid subframe bushings anyway.
