Max camber with Subaru/Toyota Crash/Camber bolts?
 

Double checking, these are the correct part numbers 901000394 or Toyota/Scion part # SU003-02818

Can you safely run two in each side, to achieve more camber?

With Camber bolts in the lower holes, the lower bolts now become crash bolts for the top holes. I got -1.9 deg camber both sides on the front with stock PP suspension.

Part numbers look correct. According to subaru, the bolts are reusable but the nuts are not. Nut #902380008. Stock subaru camber bolts (one per side) will give you -1 deg camber.

No, the second bolt is the exact same as the camber bolt, swapping it for the factory part does not net any additional camber.

-1.1 maybe a bit more if you're lucky with one set of camber bolts.

Attached are the details. As other mentioned , you'll get a maximum of -1 deg camber.

Mine is just 0.6 mm with Subaru Camber bolts...

mm? Isn't it toe that's measured in alternatively inches or mm aswell no just degrees/minutes, not camber?

Not sure why you measure camber in mm.

The manual says that these bolts can give a range of 0°± 45’ camber. If you had a stock camber of -15’, then you can get a max of -1°.

Sorry, I was in hurry, my camber went from stock 0 to around 0.5 degrees.

Double SPC camber bolt sizes;
Lower location is a 14mm bolt.
Upper location is a 16mm bolt.
I use both plus Peddars Offset Top Mounts (-.75).
All three combined achieve -2.75 front camber, without coil-overs. In my case Koni Yellows with TRD springs.
