Winter storage (rusty rotors)
I am storing my Z over the winter, but I see that after sitting for a few weeks the rotors start to get rusty. What should I do about the rust? Last year when ever the roads were clear of snow I would drive it around the block to take the rust off of the rotors but now I hear its not good to start your Z if your not going to be driving 20-30 min. (bad for the motor). Should I just leave the rust untill I unstore it or what?? Thanks.

Its just natural corrosion of the rotor. There is nothing wrong with them. Once you take her for a spin that will come right off. It just looks bad. Don't worry.
Step1
Take a closer look. Rust occurs when too much moisture has a chance to chemically react with the metal on your rotors, and generally it only occurs if the car has enough time to sit and rust.
Step2
Check out the brake pads. If your vehicle has been sitting for a while, take a look at the brake pads and the surface of the rotors. If the pads don't seem to have rust residue on them, chances are, the rust is mostly superficial. If the rotors only have rust on the surfaces exposed to the air, as opposed to large patches of rust, your rotors are merely responding to the elements.
Step3
Consult your calendar. Rusted brake rotors will cause a problem, but if the rust seems superficial, the reason for the rust might purely be a result of not properly drying your vehicle. Rain, snow, or driving in a flooded areas can also cause this.
