My car has done around 30k miles. I am looking to replace my rotors with after market brand, but not sure which would be the best brand and whether to buy slotted or premium rotors for everyday use?

Please guide. I can feel the shakes above 60 mph during braking. Break pads are fine, not sure whether replacing with better rotor would help.

 

If you live in the rust belt pull the breaks every 6 months or 6 K miles.
Make sure the pins are moving freely. Rear rotors just don't work out in the rust belt. Drums worked GREAT! PITA
