Rear Camber Adjustability Range Issue

[Subydude]

I recently had an issue with getting the rear camber on one side below -2.6 and wanted to ask the hive mind what it might be.

I've been using a local alignment shop and when we rolled the car on the rack the right rear camber was at -2.7. The left rear was -2ish. Prior to the event I had been running -2.5 with .2 degrees of toe in per side. This was after some track days so I assumed it had slipped (and it was pulling slightly to the right which tipped me off).

The left rear aligned fine after redoing the eccentric bolts, but the right rear wouldn't go below -2.6 camber. I normally sit in the car so the alignment is correct while I'm on track, but for this one I got out and tried tweaking it a bit on my own just to see if I could get some back. It still stayed at -2.6 with the eccentric all the way in the low camber setting while the other side was at -2.5 with the eccentric in the mid setting. Toe came out ok at least.

The car is lowered on H&R springs, but is stock otherwise for suspension.

I haven't had it checked on another rack to see if it's something wonky with that rack, but I did roll the car back and forth a few times on that specific one (and it was fine before) so I don't suspect the alignment machine itself. Eyeballing the wheels/tires also looks reasonable. I've gotten under it and looked at subframe bushings along with everything else and nothing appears bent or shifted.

So my question is, has anyone had an issue where rear camber won't go low enough? If so, was it a bent arm or something moved? I'm fine doing the next round of track days at -2.6 on one side and -2.5 on the other, but I'd like to get the range back so I can test lower camber settings if I want.

On H&R springs as well and have -2.2 both sides in the rear. Never tried to go higher (or is it lower )

If your car is wandering in the rear, chances are the alignment is off. Camber is the tilt of the wheel, like this . Generally a little tilt is good for cornering. Toe is the direction the tires are pointing. Generally I like my toe pointed inward like this, so it drives the power toward the middle of the car. Gives more stability under power and less surprises.

Do you have stock toe arms ? I ran into issue that my camber would go past 2.5 with .16 toe each side

I think you misread my post and I know how alignment settings work . The issue now was one side of the rear was out of adjustment to go lower, but still at -2.6 degrees of camber.

Stock everything minus drop springs, front camber plates, and a front sway bar. I run the car in Sport class with SCCA so those are the only allowed suspension modifications.

I ran out of time before an event in New England or I would have dug in more. As it is, I figured I'd ask if someone had this happen prior, and if so what it was.

The thing that bothers me is when I got the car it was able to hit lower -2.X numbers in the back on the lowering springs. I'm guessing it was either a rack issue, or something has shifted/bent a bit. I won't know for sure until I have time to dig in (or someone has an answer).

I'd guess something broke since it seems isolated to one side. I've had 18 tracks days with the springs and both have been around -2.2 the entire time.

Maybe, or at least bent. I compared sides yesterday when swapping wheels out and all the bolts were tight with no signs of bent or messed up arms. Who knows though. The car tracks straight, and drives like it normally does. As long as it continues doing that I won't worry much and will plan to dig in when I have some leeway between events.
