Rotor problems are solved!
A while back I had I decided to by new rotors off ebay. I had a damaged rear rotor and felt that I might as while buy slotted rotors instead of spending the money for an oem replacement.
I like the look... but they were terrible.
I have the J55 brakes so I ordered from gripforce and on ebay. I installed them and they felt warped and vibrated terribly. I called gripforce and they sent me a new set for the front. I took them to the machine shop before installing and found out the even though the rotors were brand new they would need to be machined due to inconsistencies in the slots. I was slightly pissed to say the least. So after two sets of bad front rotors that were brand new, I said forget it. I went to pep boys got the old fronts resurface, installed them, and the brakes have never preformed so well.
The slotted rotors for J55's from gripforce and terrible, I wouldn't suggest buying them. Hopefully I will get a full refund this week, but I still got stuck with the $60 shipping cost to send them back to CA.
Live and learn I guess...

I'm sorry to hear about your experience, but very glad you posted. Very sad.
I will say that about 6 years ago I was talking with a tire shop guy in San Diego. That's when I first learned that there are such things as $5-$10 rotors sold, obviously, for more. Not saying that's what happened. But I learned an earful from this shop owner.
Good luck and I hope you get your money back.

Whether new or used, I always check rotors with a micrometer for consistent thickness all around and check the runout, when installed on the hub, with a dial indicator. I won't use a rotor with runout of more than .004".
Sometimes, by re-indexing the rotor, you can decrease the runout to an acceptable amount.
