Camber adjustable control arm bushes

[pothole]

I've just spoken to Powerflex and they checked the measurements for me and said they were pretty sure that it would fit a 986.

He said the bushes would provide minimum of an extra degree of camber adjustability. Wouldn't that allow at least -2 overall? You can get at least -1 with the standard suspension arms, no?

I agree -2.5 would be an ideal compromise. But if I could get it to -2 total with these bushes, I settle for that given the significant cost savings even compared with camber plates.

Why can you only achieve -1.75 to -2 with plates? My experience with plates on other cars is that they typically allow for pretty extreme levels of negative camber...
