So I've always been a firm believer in using oem brake rotors as they're very high quality, last a long time, and when paired with the oem pads usually don't warp (at least not on my past BMW's).
My car has warped rotors and I'm not sure if they're oem or not, but the car has 22k so I assume they are.
I've found Zimmerman and R1Concepts drilled rotors:

The R1Concepts are especially cheap at less than $200 shipped!! I found one comment on the board about them (https://5series.net/forums/index.php...merman++rotors) - trinity autosport said "If I were you I would go with the R1Concept rotors. The rotors are by Stoptech and they drill it themselves."
Some other members liked them too.
Ultimately my question is, are either of these very likely to warp? Has anyone used them for a while? I'll be using oem pads. I just don't want to put a poor quality set on and warp them. I've done this in the past and learned my lesson, though it was a total no-name brand rotor on the E39.

For the R1 concepts you'll be better off asking Trinity for them.
I had R1 on my SRT8 Jeep (before Brembo came through with a sponsored kit) and they worked well and didn't warp. Can't tell you anything about the other brand though. If you go R1 go for the premium ones the E-line are ok, but I prefer better quality of the upgraded ones.

I currently have and sell the R1s as well. Overall they are a great rotor and I haven't had any warping issues. If you do a Google search for their rotors, you'll see every one who has them loves them.
Let me know.

Other than the rotors mentioned already, what other aftermarket rotors are available that are of high quality? I know there are a ton of different companies out there, but to save time which companies have had good reviews for quality and cost? I need new rotors and pads too so any help would be very appreciated. Thanks!
