No expert here but as I recall.....

If you what the roll center lower, wouldn't it be easier to move the inboard mounting points? Seems to me for performance use a roll center of an inch or so above ground or less is preferred (not to far below!) and that the rear roll center should be lower than the front. These are of course generalities.

Desired camber curves would depend a lot on the rubber you will be running etc (radials like more than bias plys).

You may want to buy some suspension software or try scale 'dolls' and play with the different combinations. If I was doing a chassis from scratch I would probably use an already available upright to control cost. A-arm, suspension pickup points etc are relatively cheap compaired to the cost of machining an upright! There are lots of after market uprights available. Just a thought!

So what is the project you are working on? Sounds interesting!
