alignment specs for 88 carrera

Hey guys,
I'm looking for any of you who are experts in setting alignment for street use. I like to drive so I don't want 0 camber but I dont' want to replace tires every month and wander all over the road at high speeds either. I might do an occasional autoX but not enough to buy plates and wear out tires.
I had a Saleen Mustang (which naturally wears the outside) prior to this and I had a pretty good setup.
1/16" total toe out
1.5 degrees negative camber
3.5 degrees positive caster to restablize car at high speeds with toe out.
It was pretty solid but I'm sure the 911 is different. I had my front tires balanced yesterday and the inside is wearing excessively so I need to get the alignment done soon.
Thanks all
Kevin
