With the OEM tires I don't think you'll have any rubbing issues. When you look in the inner wheel well do you have rubber marks? In terms of your settings that is 100% correct. You want to run it soft in the front and stiffer in the rear. The settings will be dependent on the surface as well as the course but that is the beauty of having a fully adjustable suspension. The picture below is my car loaded on the track and even with the OEM tires tucked I'm not rubbing. If the tire is rolling over it might appear like you have a rub.

Front
-1.0* camber (now -1.2*)
6.8* caster
.something toe(can't remember, but near stock)
Rear
0* camber
0* toe
No fender tire rub, but had to fill to 45 psi to address soft sidewalls. Car still understeers. Will be trying softer front and stiffer rear dampening to see if that helps understeer. Last solo course was slalom city.

I would suggest 8-12 front and 15-20 rear on the damping settings depending on the course and surface; tire compound also plays into these settings as well. I generally run 28-34 PSI depending on the surface with the OEM tires. It looks like you have aftermarket wheels and tires, what are you running?
I would also run the following alignment settings:
Front
-1.2* to -1.5* camber
-1/16" - 1/8" toe-in
7.5* to 8.5* caster
Rear
-.8* to -1.0* camber
0 to -1/16" toe-in
These setting will help your tire roll over issue and you'll have better overall corner grip. You have to be careful with rear camber as too much will affect the ability to put power down. Please feel free to call, email or PM me anytime with questions.
