On the MR2, Toyota offers "crash bolts" to adjust the camber. They're basically strut->knuckle bolts with a smaller inner diameter to allow for more camber.
Standard diameter is 15mm, IIRC.
13.9mm, 13.3mm, and 12.4mm are available from here:

The Camry shares the same bolt/nut on the strut->knuckle housing at the
rear, so it should be possible to use them. I'm not sure if the fronts are the same. Toyota offers different diameters for the fronts on the Camrys anyway.
Otherwise, you'll need an expensive camber kit with fancy camber plates.
BTW, that's too much negative camber for straight line stability.

Just an FYI.
