My rotors are all beyond the point where they should have been replaced. It's a struggle to remove calipers because of how ridged they are. I don't understand the differences between cheap and expensive rotors.
My question; What exactly is the science behind good and bad brake rotors?
I struggle to see what the difference is between a good and bad rotor. All the research I can find is about automotive brake rotors.
Essentially, drilled rotors really are more aesthetic than anything else, but do provide extra venting. Slotted helps expel brake dust and gas and possibly to bite into the pads.
For motorcycle rotors, I see that galfer's wave rotors "Keeps the brake system cooler by allowing air to pass over every point of a brake pad surface." Mr. galfer says they have better bite while keeping rotors cooler. Yet, you very rarely see them as stock on any performance oriented motorcycle, nor in any race setting. They do look really cool though.
Basically, I want some snazzy looking brakes, but I also don't wanna break the bank or lose any braking performance, and gaining performance would be nice. What blows me away is that even cheaper brake rotors are AT LEAST 200 bucks a POP, OEM is like 300 each from what I'm seeing.
Maybe LDH would know these answers as he actually probably sees what rotors work and what don't all the time, but I for sure have no clue what the difference would be between 200 dollar chinese ebay rotors, 400 dollar EBC replacement rotors, and 600 dollar galfer or OEM rotors.
