CMP Camber Arms Review

[simplem3]

Looking for reviews from personal experiences with performance and durability. Are the rod end boot effective?

I have them sitting in a box, not yet installed, but have had a good look at them.
I think the boot would be effective yes, especially since the arms sit in a recessed area in the subframe which probably eliminates a lot of road dirt already.

If you are worried about the exposed bearing, perhaps look at the Bimmerworld ones, those are sealed. There probably are other brands too with a sealed OE like ball joint.

On the car for a couple of thousand miles. No problems or complaints. The inner boots seem to be holding up fine.

Ground Control control arms also have a sealed bearing. Adjuster is on the outside, too, which makes adjustment easier.

I have the GC's as well, they are legit. No issues.

I have the Turner arms which has the adjuster near the outer end which makes camber adjustments much easier. Unless the adjuster is towards the outer end then it partly defeats the purpose of a rear camber arm.

Unfortunately the rod end with the turner arms didn't last long so I switched to a bushing.

Running GC’s as well. Can’t go wrong with them imo

[simplem3]

Good input from all! Glad to see positive experiences with GC as I didn’t consider them.

Not having run adjustable arms on the e46, what is the main issue with having the adjuster in the center? Seems like the logical place to put it imo for a couple reasons, but I'd like to hear why before I install this set of ECS arms I've had laying around for a few years now...

You have to loosen jam nuts to make a camber adjustment. The further inboard the jam nuts are, the more difficult it is to get to the nut to loosen and tighten.

Ok, so just hardware accessibility and it looks to be ok.

Yup. My only other concern might be the inner jam nut on the left side. Heat from the exhaust could possible cause the hardware to seize if the arm is aluminum. The hardware will be steel, dissimiliar metals will cause corrosion.
