Hit a bad pothole. Have alignment numbers. What's bent?
I hit a *very* bad pothole on the right side of the car which bent the front right and rear wheel. They are fixed and the car no longer shudders.
I took the car to an alignment shop and got an initial reading. The numbers aren't great. I think it's safe to say the struts are bent, causing the negative camber. The toe isn't so bad and there's most likely enough adjustment available to correct it. Do you think I can get away without replacing any of the suspension arms? If not, knowing the geometry of a Boxster suspension and robustness of the different arms, what would most likely be bent? I know I'm asking for speculation, but I don't have access to a lift and so it's hard to compare the damaged side with the undamaged side. Thanks for your thoughts, everyone.

Sorry to hear.
US roads and potholes...oh boy
I still would like to see mobile Lidar pothole detection/warning apps.
Maybe...someday...

I have 2 LCAs that I want to get rid of. $50 for the pair. I'll sell the trailing arm for $20 if you want it. Plus shipping.
LCAs, Trailing Arms, RCA

Nearly impossible to tell online. Lift it upz take off wheel and have a poke around...should be fairly obvious

Generally you can't tell by looking if the upright is bent. Control arms and strut tower should be obvious though.

The front right strut was damaged and so I have ordered a new one. I have taken the rear right corner apart and it's not clear what's wrong—as far as I can tell neither the strut or control arms are bent.
What else should I check?

I think you know that camber is adjustable and it may be just misaligned due to impact, instead of something is broken or bent, right? Did the shock get bottomed out when running over a pothole? Arms are aluminum so I’d think it will crack under stress.

I had a thought. Though the car went over the pothole on the right side, the left side numbers were thrown off too, which could suggest that the subframe shifted? (I suppose that's best case scenario—rather than subframe or frame bent).
From the damage, the left side alignment did the opposite of the right, basically—less camber camber and less toe on the left, more camber and more toe on the right.
I've looked at the parts diagrams and the service manual, but I can't tell what are the big bolts I should examine for shifting. Can someone point me in the right direction?
Thanks

The subframe could be bent or cracked. No disaster, used parts are available, not too hard to change.
