What would be the best option right now? What is everyone's experiences with any of these?
Some advice on keeping whatever rotors you use from becoming "warped" themselves: don't keep the brake pedal depressed once you come to a complete stop after an extended application of the brakes.
Whether it's briefly letting up a couple of times or just shifting into park and releasing them altogether, the objective is to prevent the brake pads from baking onto the rotors when they're super-heated, as that can cause the rotors to become uneven in those exact spots.
So for example, you are traveling along at 55 mph and suddenly notice a yellow light at the upcoming traffic signal, causing you to quickly and forcefully apply the brakes to come to a stop. Once your vehicle has come to a stop, if you just leave your foot on the brake the whole time while waiting for the light to turn green, that could lead to the condition which is commonly (mis?)diagnosed as warped rotors. To avoid this, simply release the brakes a couple of times (or altogether after shifting to park) while sitting still.
This is certainly not a cure-all for warped rotors, but it will definitely go a long way to mitigating the circumstances which can lead to rotors needing to be replaced due to vibration during high speed braking, aka brake jutter.
