pwrslit/crossdrilled rotors, make noise?

[HiddenNshadows]

I just had some ebay(i know i know) rotors & brake pads put on. I would have done it myself but waiting on clear weather for 2 weeks just didnt cut it. So i had a local shop do it. Now when i brake I do stop alot! faster but i have this vibration sound when i slow down from 60-30 coupled with a slight high pitched sqeek. The sqeek is from not using the anti-sqeek stuff but the vibration, has left me & another mechanic stumpd. I thot it maybe in just due to the rotor. Has anyone had this problem or know what it maybe? I could rly use help. my car stops great but the noise & vibration is annoying. Any info would help!
Could this noise be my rotors? ^& normal or would ex brake pads on a dx cause this.

Just an fyi you stop better with stock rotors, slotted/drilled is only for cooling which you will never need. Anyways the cheap rotor is probably warped already or even came that way

^+1.

If you think your braking is better, it's all in your head. The brake pads are what really determine braking force. Slotted/drilled rotors are supposed to aid in cooling which reduces brake fade and warping. But you'll probably never experience fade driving normally on the street so there's no need. They also tend to wear your pads faster.

That said, being cheap no-name rotors, they probably came defective... Get what you pay for.. If I were you, I'd replace those thing ASAP. I wouldn't trust my life(literally) with those things.
