I dont wanna tell you what to do....but i heard that sometimes those brake rotors off ebay will rust and arnt very good quality... just my 2 cents

I think the rotor rust anyways if u dont drive the car for a while and leave in the rain or something then after u drive the car and hit the brake then the rust goes away. Thats how it is on my stock rotors.
what happens if the rotor is bad quality dose it mess up the pads faster or something like that?
These r good price do, becasue i bought my two front rotors from BigO tires and they were like $150 for two of them.

Rotors and pads are something I wouldn't go cheap on...ebay rotors are rumored to warp very quickly...meaning new rotors are needed. I suggest going to stealth316 and reading his article on brake upgrades. This might help you choose what is best for you.
