badrich,
putting negative camber on is one way of helping a clearance problem. If your wishbones are designed, to already give 1 degree negative to 1" suspension travel, you might already have enought camber change built in. From my limited experience with suspension a bit more negative is better than positive camber - so its a fix.

Some Cobra manufacturers, builders like myself just dont put enough thought into design, or get wheels specially made for their cars, and when you want to fit original Trigo or other wheels, all sorts of problem arise.

The bottom line is start with a body/seat and four wheels, and then build the rest. Knowledgeable people write books on building race cars but people like myself (use to) pick out some excerpts and then make the usual balls ups!
