Rust ring on front rotors/ intro!

EDIT: Yeah I have an appointment with Porsche dealer near my house on Saturday for balancing. So I'll check my rotors when I get home. I really think it's a balancing issue that picture makes my rotors look a lot worse than they do in person. But to be safe I'll try and inspect them as best I can.

If the steering wheel is steady going down the road & you brake causing the steering wheel to shimmy then you have a rotor problem. Look for new wheel weights on the inside of the wheels to see if the tires were balanced when installed.

Not necessarily, I have seen suspension issues (loose tie rod) cause a shimmy under braking. If you get no pulse in the pedal, but the steering shimmies, it could be suspension related.

The rust looks like a minor groove in the rotor. It should go away as the new pads seat themselves in, though it may take a few hundred miles.

That's certainly possible, I just suggested the next step she can do herself while attempting to bed her brake pads to the rotors & eliminate a possible contributer to ride vibrations & shimmys.

As far as I can tell I don't have any shimmy in the wheel while breaking on even road. Colorado has a ton of really crappy pavement, I try to do my observations on nice patches Getting balanced tomorrow so hopefully my wheel shake will go away although I think I might need alignment too.

I actually heard a *clunk* on the highway while driving yesterday and thought I kicked up a rock under my passenger tire, I think it might have been son existing weights on the tire because my steering shake is not nearly as bad as it was lol.

OK sounds like the brakes are OK. Alignment has nothing to do with steering wheel shimmy. I'm betting on a bent wheel, tell them to check for a bent wheel.
