If you are running street tyres then its probably the camber change thats more important than the camber initially...
The idea is to run 0 degrees on the straights, and set the tie rods so that as the car leans out in cornering the tyre keeps the maximum contact patch with the road...
This will give you the maximum grip on the straights and maximum in cornering....
The outside wheel is the most critical to get right as thats where all the grip is being found, if your camber change under cornering is off on the inside wheel then it isnt as critical as the outside wheel...
Running lots of neggy camber on the straights gives less contact, less drive, more tyre wear etc etc...
