Too much camber?

[Toahk]

Have 89 s13, d2 coilovers with adjustable camber in front, getting some ruca's for the rear. Have some 15x6, 0 offset wheels. Here are some pic's, im assuming the tires will wear pretty quick at this camber, or is it acceptable for the street? how much should I adjust the camber in the rear to get acceptable tire wear? thanks.

Tire wear = - 0.5 or 0
