Neg. camber machined rear spacers???

How much camber results from twisting? Can't be much. Although I suppose in theory the twist beam acts like a semi-trailing arm...

I think it's better to account for bumps/road surface anomalies than to not.
Also, when a radial tire gets cornered hard, it can roll underitself; negative camber can help prevent that.

Finally, I've personally witnessed not only my car's rear tires, but also another fellow echo owner's rear tires have more outside wear than inside.
Obviously some negative camber would help even that out.
