Default Whats the difference between these Megan Arms?

I have been reading and speaking to a few other CL members here. But after all the posts and messages back and forth. I am a bit confused still on what all these rear arms do. Seems like they all do the same thing. Correct camber. Please give your input on what these arms actually do and which one would be sufficient to correct the camber for the rear.

I had the first and third pic you posted. I assume you want to correct negative camber to positive? To simplify it I can speak on the ones I had. The top pic brings the lower portion of the wheel in towards the center of the car to make your wheel have full contact patch on the road surface. The last pic will push the top of the tire out toward the rear quarter panel to correct negative camber (which can get close to the body) depending on how much positive camber you want. Hope that provides some info which isn't written textbook but provides an idea.

Default Thank You Sffd103

Yes i do want to correct negative camber. Yes that explanation did clear up what the first and third arm do. Wish Megan would simply note that on their site. Thank you for always giving your input on mine and everyone elses posts.

Everyone feel free to give your 2 cents. Also, anyone know what the Megan Rear adjustable no.1 Upper arm does? (middle picture)

Pic #1 replaces the factory LCA; it will allow for camber adjustment.

Pic #3 replaces one of the factory multi-link arms; the Megan arm allows for camber adjustment.

On the rear tires, inner tread is being eaten out rapidly and there is still life in the middle/outter portion of tire. I am lowered on Tein S tech springs, didnt think it would be that bad. But apparently its a toe and camber issue. What do you think, can factory arms make the proper adjustment to align toe to 0 and camber to a minimal amount?

For the front i have inner tire wear as well. I will be getting the FIGS FRONT LOWER ARM REAR MOUNT #2 POLYURETHANE BUSHING 90 HIGH PERFORMANCE and when i get it aligned tell them adjust toe to 0

Before your tires get eaten through to the cords, have a tire place dismount the tires and flip them and re-install.

too late, one of the rear tires have a slow leak somewhere. I dont know where it is coming from but the inner portion of tire is done. No more tread. My Track wheels are on now. Going to get an alignment if shops are open this week or early next week
