Got a brand new GT Avalanche Elite in the mail today and as I'm putting it together I test the front wheel only to find the rotor keeps making contact with the break pads.
This is my first bike with hydraulic breaks so this is all new gear to me. These rotors are supposed to be flat, right? This seems bent to me but maybe I'm wrong? Took it off the wheel to get a good picture on it resting on a flat surface.

Yep that’s bent
Don’t put your greasy fingers all over the rotor. The oils in your hands will contaminate the rotor and make them noisy and shitty.
A rotor should be straight. But you can bend them straight pretty easily.
Most brakes and rotors will rub the first time you set them up. It takes some finess to get them then perfect.
If you bought this from a bike shop, have them replace the rotor as it’s warped. If not, contact GT and see if they will warranty replace the rotor.
Otherwise install it. Use some clean pliers and a clean towel and bent it straight/true it while spinning it until it doesn’t rub.
Then spray it with rubbing alcohol and hopefully that will clean the contaminants off.
That one seems a bit more out of whack than normal. My experience with new rotors is they are rarely flat, that seems excessive
Bold to assume American walls are straight.
(No yeah your rotors bent lmao).
Try to avoid putting your fingers on the rotor surface. The oils can contaminated them
