Rear camber adjustment

[Ender]

My TII has terrible negative camber in the rear, and I believe it's uneven as well (one side has more negative camber than the other). I had this problem even before I lowered the car, so that ultimately isn't the cause. I see Racing Beat and RotorSports offer rear camber adjusters, but I'd like to know how they work and what their products can do to solve my problem. For now I'd like to just return the car's alignment to factory spec, that's what Intrax suggested for street/track use.

From what I can tell, Racing Beat's rear camber adjuster ($116) replaces one fixed length link near the middle of the rear subframe. It's item 14008. "The immediate range of adjustment is .60 degrees less negative camber to .77 degrees more negative camber. With careful inspection and possibly some minor dimpling of the floor pan, this range can be nearly doubled." First off, I don't know if I can reach factory spec using that, and I also don't know if it will even out the camber between both rear wheels. That's one reason RotorSport's solution sounds better at first glance.

RotorSport's camber adjusters, you need two: AWR E015R/L ($175/pair). "Locking adjuster to facilitate positive camber adjustments. Control camber individually for both rear wheels." What I don't get is where you install them...

I'm also curious about other options, I just haven't seen other adjusters yet.
