It also can depend on your ride height and driving habits. If you never trail brake or apply brakes very sparingly with the wheel turned or have close to stock ride height you can probably get away with more than -3* of front camber without ever having clearance issues with most of your camber from adjustable top plates.

If the opposite is true (lowered and aggressive trail braking into turns often) you'd probably be well served with most of your negative camber added at the knuckles without causing any tire to strut rubbing and the rest from the upper plates. If you're still making contact on the upper endlink you can try looking into some lower profile aftermarket end links and/or putting an indentation in the section of the frame making contact to avoid binding.
